  Clark University
  Clark University is a private research university and liberal arts college in Worcester, Massachusetts. Founded in 1887, it is the oldest educational institution founded as an all-graduate university. Clark now also educates undergraduates. It is one of only three New England universities, along with Harvard and Yale, to be a founding member of the Association of American Universities, an organization of universities with the most prestigious profiles in research and graduate education. Clark withdrew its membership in 1999, citing a conflict with its mission; it is one of only four schools to do so. Clark is one of 40 schools profiled in the book Colleges That Change Lives by Loren Pope.
  Clark University was founded by American businessman Jonas Gilman Clark in 1887. He started the university with a million dollars, and later added another million dollars to the university fund because he feared the university might someday face lack of funds. The university was opened on October 2, 1889 as the first all-graduate university in the United States.

• Alan Sokal
  Alan David Sokal (/ˈsoʊkəl/; born 1955) is a professor of mathematics at University College London and professor of physics at New York University. He works in statistical mechanics and combinatorics. To the general public he is best known for his criticism of postmodernism, resulting in the Sokal affair in 1996 when his deliberately nonsensical paper was published by Duke University's Social Text.
  Sokal received his B.A. from Harvard College in 1976 and his Ph.D. from Princeton University in 1981. He was advised by Arthur Wightman. In the summers of 1986-1988, Sokal taught mathematics at the National Autonomous University of Nicaragua, when the Sandinistas were heading the elected government.
  Sokal’s research lies in mathematical physics and combinatorics. In particular, he studies the interplay between these fields based on questions arising in statistical mechanics and quantum field theory. This includes work on the chromatic polynomial and the Tutte polynomial, which appear both in algebraic graph theory and in the study of phase transitions in statistical mechanics. His interests include computational physics and algorithms, such as Markov chain Monte Carlo algorithms for problems in statistical physics. He also co-authored a book on quantum triviality.

  Albert Edelfelt
  Albert Gustaf Aristides Edelfelt (21 July 1854 – 18 August 1905) was a Swedish-speaking Finnish painter.
  Albert Edelfelt was born in Porvoo, Finland. His father Carl Albert was an architect. Edelfelt admired the poet Johan Ludvig Runeberg, who was a friend of the family. The company of Runeberg had a lasting impact on Edelfelt, who from time to time turned to scenes from Finnish history in his paintings. Edelfelt went on to illustrate Runeberg's epic poem The Tales of Ensign Stål. He studied art in Antwerp (1873–1874), Paris (1874–1878) and Saint Petersburg (1881–1882).
  He married Baroness (friherinnan) Ellan de la Chapelle in 1888 and they had one child.
  Edelfelt was one of the first Finnish artists to achieve international fame. He enjoyed considerable success in Paris and was one of the founders of the Realist art movement in Finland. He influenced several younger Finnish painters and helped fellow Finnish artists such as Akseli Gallen-Kallela to make their breakthrough in Paris. Among his students was Leon Bakst.

  Albert Einstein
  Albert Einstein ( /ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics. While best known for his mass–energy equivalence formula E = mc² (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory within physics.
  Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.

  Aristotle
  Aristotle (Ancient Greek: Ἀριστοτέλης, Aristotélēs) (384 BC – 322 BC) was a Greek philosopher and polymath, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality, aesthetics, logic, science, politics, and metaphysics.
  Aristotle's views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the 19th century. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic. In metaphysics, Aristotelianism had a profound influence on philosophical and theological thinking in the Islamic and Jewish traditions in the Middle Ages, and it continues to influence Christian theology, especially the scholastic tradition of the Catholic Church. His ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotle's philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (Cicero described his literary style as "a river of gold"), it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.

  Arthur Koestler
  Arthur Koestler CBE (5 September 1905, Budapest – 1 March 1983, London) was a Hungarian-British author and journalist. Koestler was born in Budapest and, apart from his early school years, was educated in Austria. In 1931 Koestler joined the Communist Party of Germany but, disillusioned by Stalinist atrocities, he resigned in 1938. In 1940 he published his novel Darkness at Noon, an anti-totalitarian work, which gained him international fame.
  Over the next 43 years from his residence in Great Britain, Koestler espoused many political causes and wrote novels, memoirs, biographies, and numerous essays. In 1968, he was awarded the prestigious Sonning Prize "for outstanding contribution to European culture" and, in 1972, he was made a Commander of the Order of the British Empire (CBE). In 1976, Koestler was diagnosed with Parkinson's disease and, in 1979, with terminal leukaemia. In 1983 he and his wife committed suicide at home in London.

  Auguste Comte
  Isidore Auguste Marie François Xavier Comte (19 January 1798 – 5 September 1857), better known as Auguste Comte [oɡyst kɔ̃t], was a French philosopher. He was a founder of the discipline of sociology and of the doctrine of positivism. He may be regarded as the first philosopher of science in the modern sense of the term.
  Strongly influenced by the Utopian socialist Henri Saint-Simon, Comte developed the positive philosophy in an attempt to remedy the social malaise of the French revolution, calling for a new social doctrine based on the sciences. Comte was a major influence on 19th century thought, impacting the work of social thinkers such as Karl Marx, John Stuart Mill, and George Eliot. His concept of sociologie and social evolutionism, though now outdated, set the tone for early social theorists and anthropologists such as Harriet Martineau and Herbert Spencer, evolving into Modern academic sociology presented by Émile Durkheim as practical and objective social research.
  Comte's social theories culminated in the "religion of humanity", which was influential to the development of religious humanist and Secular Humanist organizations in the 19th century. Comte likewise coined the word "altruism".

  Averroes
  ʾAbū l-Walīd Muḥammad bin ʾAḥmad bin Rušd (Arabic: أبو الوليد محمد بن احمد بن رشد‎), better known just as Ibn Rushd (Arabic: ابن رشد‎), and in European literature as Averroes ( /əˈvɛroʊ.iːz/; April 14, 1126 – December 10, 1198), was an Andalusian Muslim polymath; a master of Aristotelian philosophy, Islamic philosophy, Islamic theology, Maliki law and jurisprudence, logic, psychology, politics, Arabic music theory, and the sciences of medicine, astronomy, geography, mathematics, physics and celestial mechanics. He was born in Córdoba, Al Andalus, modern-day Spain, and died in Marrakesh, Morocco. His school of philosophy is known as Averroism.
  Ibn Rushd was a defender of Aristotelian philosophy against claims from the influential Islamic theologian Ghazali who attacked philosophy so it would not become an affront to the teachings of Islam.
  Averroes' name is also seen as Averroës, Averroès or Averrhoës, indicating that the "o" and the "e" form separate syllables. Averroes is a Latinisation of a Hebrew transcription of the Arab name Ibn Rushd.

  Benjamin Franklin
  Benjamin Franklin (January 17, 1706 [O.S. January 6, 1705] – April 17, 1790) was one of the Founding Fathers of the United States. A noted polymath, Franklin was a leading author, printer, political theorist, politician, postmaster, scientist, musician, inventor, satirist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and the glass 'armonica'. He formed both the first public lending library in America and the first fire department in Pennsylvania.
  Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity; as an author and spokesman in London for several colonies, then as the first United States Ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical and democratic values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."

• Carl Gustav Hempel
  Carl Gustav "Peter" Hempel (January 8, 1905 in Oranienburg, Germany - November 9, 1997 in Princeton, New Jersey) was a philosopher of science and a major figure in 20th-century logical empiricism. He is especially well known for his articulation of the Deductive-nomological model of scientific explanation, which was considered the "standard model" of scientific explanation during the 1950s and 1960s. He is also known for the Raven paradox, which highlights the problem of induction.
  Hempel studied mathematics, physics, and philosophy at the University of Göttingen, Heidelberg and Berlin. In Göttingen he encountered David Hilbert and was impressed by his attempt to base all of mathematics on solid logical foundations derived from a limited number of axioms (Hilbert's Program). Having moved to Berlin he participated in a congress on scientific philosophy in 1929, where he met Rudolf Carnap and became involved in the Berlin Circle of philosophers that was associated with the Vienna Circle. In 1934 he received his doctoral degree from the University of Berlin with a dissertation on probability theory.

  Carl Jung
  Carl Gustav Jung (/ˈjʊŋ/ YUUNG; German: [ˈkarl ˈɡʊstaf ˈjʊŋ]; 26 July 1875 – 6 June 1961) was a Swiss psychiatrist, the founder of analytical psychology. Jung is considered the first modern psychiatrist to view the human psyche as "by nature religious" and make it the focus of exploration. Jung is one of the best known researchers in the field of dream analysis and symbolization. While he was a fully involved and practicing clinician, much of his life's work was spent exploring tangential areas, including Eastern and Western philosophy, alchemy, astrology, and sociology, as well as literature and the arts.
  Jung considered individuation, a psychological process of integrating the opposites including the conscious with the unconscious while still maintaining their relative autonomy, necessary for a person to become whole. Individuation is the central concept of analytical psychology.
  Many psychological concepts were first proposed by Jung, including the archetype, the collective unconscious, the complex, and synchronicity. Popular psychometric instruments like the Myers-Briggs Type Indicator (MBTI), have been principally developed from Jung's theories.

  Carl Reichenbach
  Baron Dr. Carl (Karl) Ludwig von Reichenbach (full name: Karl Ludwig Freiherr von Reichenbach) (February 12, 1788 – January 1869) was a notable chemist, geologist, metallurgist, naturalist, industrialist and philosopher, and a member of the prestigious Prussian Academy of Sciences. He is best known for his discoveries of several chemical products of economic importance, extracted from tar, such as eupione, waxy paraffin, pittacol (the first synthetic dye) and phenol (an antiseptic). He also dedicated himself in his last years to research an unproved field of energy combining electricity, magnetism and heat, emanating from all living things, which he called the Odic force.
  Reichenbach was educated at the University of Tübingen, where he obtained the degree of doctor of philosophy. At the age of 16 he conceived the idea of establishing a new German state in one of the South Sea Islands, and for five years he devoted himself to this project.
  Afterwards, directing his attention to the application of science to the industrial arts, he visited manufacturing and metallurgical works in France and Germany, and established the first modern metallurgical company, with forges of his own in Villingen and Hausach in the Black Forest region of Southern Germany and later in Baden.

  Erasistratus
  Erasistratus (Greek: Ἐρασίστρατος; 304 BC – 250 BC) was a Greek anatomist and royal physician under Seleucus I Nicator of Syria. Along with fellow physician Herophilus, he founded a school of anatomy in Alexandria, where they carried out anatomical research. He is credited for his description of the valves of the heart, and he also concluded that the heart was not the center of sensations, but instead it functioned as a pump. Erasistratus was among the first to distinguish between veins and arteries. He believed that the arteries were full of air and that they carried the "animal spirit" (pneuma). He considered atoms to be the essential body element, and he believed they were vitalized by the pneuma that circulated through the nerves. He also thought that the nerves moved a nervous spirit from the brain. He then differentiated between the function of the sensory and motor nerves, and linked them to the brain. He is credited with one of the first in-depth descriptions of the cerebrum and cerebellum.

  Ernest Jones
  Alfred Ernest Jones (1 January 1879 – 11 February 1958) was a British neurologist and psychoanalyst, and Sigmund Freud’s official biographer. Jones was the first English-speaking practitioner of psychoanalysis and became its leading exponent in the English-speaking world where, as President of both the British Psycho-Analytical Society and the International Psychoanalytic Association in the 1920s and 1930s, he exercised unmatched influence in the establishment of its organisations, institutions and publications.
  Jones was born in Gowerton (formerly Ffosfelin), an industrial village on the outskirts of Swansea, the son of a colliery engineer.
  He was educated at Swansea Grammar School, Llandovery College, Cardiff University and University College London (UCL), where in 1901 he obtained a first-class honours degree in medicine and obstetrics, followed by an MD and membership of the Royal College of Physicians in 1903. He was particularly pleased to receive the University’s gold medal in obstetrics from his distinguished fellow-Welshman, Sir John Williams.

  Ernst Mayr
  Ernst Walter Mayr (July 5, 1904 – February 3, 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned taxonomist, tropical explorer, ornithologist, historian of science, and naturalist. His work contributed to the conceptual revolution that led to the modern evolutionary synthesis of Mendelian genetics, systematics, and Darwinian evolution, and to the development of the biological species concept.
  Neither Charles Darwin nor anyone else in his time knew the answer to the species problem: how multiple species could evolve from a single common ancestor. Ernst Mayr approached the problem with a new definition for the concept of species. In his book Systematics and the Origin of Species (1942) he wrote that a species is not just a group of morphologically similar individuals, but a group that can breed only among themselves, excluding all others. When populations within a species become isolated by geography, feeding strategy, mate selection, or other means, they may start to differ from other populations through genetic drift and natural selection, and over time may evolve into new species. The most significant and rapid genetic reorganization occurs in extremely small populations that have been isolated (as on islands).

  Erwin Schrödinger
  Erwin Rudolf Josef Alexander Schrödinger ( /ˈʃroʊdɪŋər/; German: [ˈɛʁviːn ˈʃʁøːdɪŋɐ]; 12 August 1887 – 4 January 1961) was an Austrian born physicist and theoretical biologist who was one of the fathers of quantum mechanics, and is famed for a number of important contributions to physics, especially the Schrödinger equation, for which he received the Nobel Prize in Physics in 1933. In 1935 he proposed the Schrödinger's cat thought experiment.
  In 1887 Schrödinger was born in Vienna, Austria to Rudolf Schrödinger (cerecloth producer, botanist) and Georgine Emilia Brenda (daughter of Alexander Bauer, Professor of Chemistry, Technische Hochschule Vienna).
  His mother was half Austrian and half English; His father was Catholic and his mother was Lutheran. Despite having a religious background, he was later said to be an atheist.
  In 1898 he attended the Akademisches Gymnasium. Between 1906 and 1910 Schrödinger studied in Vienna under Franz Serafin Exner(1849–1926) and Friedrich Hasenöhrl (1874–1915). He also conducted experimental work with Karl Wilhelm Friedrich "Fritz" Kohlrausch 1884–1953.

  Eugene Wigner
  Eugene Paul "E. P." Wigner (Hungarian Wigner Jenő Pál; November 17, 1902 – January 1, 1995) FRS was a Hungarian American theoretical physicist and mathematician.
  He received a share of the Nobel Prize in Physics in 1963 "for his contributions to the theory of the atomic nucleus and the elementary particles, particularly through the discovery and application of fundamental symmetry principles"; the other half of the award was shared between Maria Goeppert-Mayer and J. Hans D. Jensen. Wigner is important for having laid the foundation for the theory of symmetries in quantum mechanics as well as for his research into the structure of the atomic nucleus. It was Eugene Wigner who first identified Xe-135 "poisoning" in nuclear reactors, and for this reason it is sometimes referred to as Wigner poisoning. Wigner is also important for his work in pure mathematics, having authored a number of theorems.
  Wigner was born in Budapest, Austria-Hungary, into a middle class Jewish family. He had two sisters, one of whom later married Paul Dirac. At the age of 11, Wigner contracted what his parents believed to be tuberculosis. They sent him to live for six weeks in a sanatorium in the Austrian mountains. During this period, Wigner developed an interest in mathematical problems. From 1915 through 1919, together with John von Neumann, Wigner studied at the Fasori Evangélikus Gimnázium, where they both benefited from the instruction of the noted mathematics teacher László Rátz. In 1919, to escape the Béla Kun communist regime, the Wigner family briefly moved to Austria, returning to Hungary after Kun's downfall. Partly as a reaction to the prominence of Jews in the Kun regime, the family converted to Lutheranism.

  Francis Bacon
  Francis Bacon, 1st Viscount St Alban(s),KC (22 January 1561 – 9 April 1626) was an English philosopher, statesman, scientist, jurist and author. He served both as Attorney General and Lord Chancellor of England. Although his political career ended in disgrace, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method during the scientific revolution.
  Bacon has been called the creator of empiricism. His works established and popularised inductive methodologies for scientific inquiry, often called the Baconian method, or simply the scientific method. His demand for a planned procedure of investigating all things natural marked a new turn in the rhetorical and theoretical framework for science, much of which still surrounds conceptions of proper methodology today.
  Bacon was knighted in 1603, and created both the Baron Verulam in 1618, and the Viscount St Alban in 1621; as he died without heirs both peerages became extinct upon his death. He famously died by contracting pneumonia while studying the effects of freezing on the preservation of meat.

  Francis Crick
  Francis Harry Compton Crick OM FRS (8 June 1916 – 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist, and most noted for being a co-discoverer of the structure of the DNA molecule in 1953 together with James D. Watson. He, Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
  Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the genetic code. He is widely known for use of the term “central dogma” to summarize an idea that genetic information flow in cells is essentially one-way, from DNA to RNA to protein.
  During the remainder of his career, he held the post of J.W. Kieckhefer Distinguished Research Professor at the Salk Institute for Biological Studies in La Jolla, California. His later research centered on theoretical neurobiology and attempts to advance the scientific study of human consciousness. He remained in this post until his death; "he was editing a manuscript on his death bed, a scientist until the bitter end" according to Christof Koch.

He did important work on the anatomy of the liver, and he wrote an early pediatric text on rickets. An experiment he performed helped debunk the balloonist theory of muscle contraction by showing that when a muscle contracted under water, the water level did not rise, and thus no air or fluid could be entering the muscle.
  Glisson was born in Bristol and was educated in Rampisham, Dorset, and at Caius College, Cambridge. Glisson is a well-known medical eponym; he was for forty years Regius Professor of Physic at Cambridge. He died in London. The Glisson family can be traced to present-day Somerset.

  Friedrich Wöhler
  Friedrich Wöhler (31 July 1800 – 23 September 1882) was a German chemist, best known for his synthesis of urea, but also the first to isolate several chemical elements.
  He was born in Eschersheim, which belonged to Hanau at the time but is nowadays a district of Frankfurt am Main. In 1823 Wöhler finished his study of medicine in Heidelberg at the laboratory of Leopold Gmelin, who arranged for him to work under Jöns Jakob Berzelius in Stockholm. He taught chemistry from 1826 to 1831 at the Polytechnic School in Berlin until 1839 when he was stationed at the Polytechnic School at Kassel. Afterwards, he became Ordinary Professor of Chemistry in the University of Göttingen, where he remained until his death in 1882. In 1834, he was elected a foreign member of the Royal Swedish Academy of Sciences.
  Wöhler is regarded as a pioneer in organic chemistry as a result of his (accidentally) synthesizing urea in the Wöhler synthesis in 1828. This discovery has become celebrated as a refutation of vitalism, the hypothesis that living things are alive because of some special "vital force". However, contemporary accounts do not support that notion. This Wöhler Myth, as historian of science Peter J. Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'". Nevertheless, it was the beginning of the end of one popular vitalist hypothesis, that of Jöns Jakob Berzelius that "organic" compounds could only be made by living things.

  Galen
  Aelius Galenus or Claudius Galenus (b. 129 AD, d. circa 200 AD), better known as Galen of Pergamon (modern-day Bergama, Turkey), was a prominent Roman (of Greek ethnicity) physician, surgeon and philosopher. Arguably the most accomplished of all medical researchers of antiquity, Galen contributed greatly to the understanding of numerous scientific disciplines, including anatomy,physiology, pathology,pharmacology, and neurology, as well as philosophy and logic.
  The son of Aelius Nicon, a wealthy architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. He traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors.

  Galileo Galilei
  Galileo Galilei (Italian pronunciation: [ɡaliˈlɛːo ɡaliˈlɛi]; 15 February 1564 – 8 January 1642), was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the Father of Modern Science".
  His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honour), and the observation and analysis of sunspots. Galileo also worked in applied science and technology, inventing an improved military compass and other instruments.
  Galileo's championing of heliocentrism was controversial within his lifetime, when most subscribed to either geocentrism or the Tychonic system. He met with opposition from astronomers, who doubted heliocentrism due to the absence of an observed stellar parallax. The matter was investigated by the Roman Inquisition in 1615, and they concluded that it could only be supported as a possibility, not as an established fact. Galileo later defended his views in Dialogue Concerning the Two Chief World Systems, which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo up until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", forced to recant, and spent the rest of his life under house arrest. It was while Galileo was under house arrest that he wrote one of his finest works, Two New Sciences. Here he summarized the work he had done some forty years earlier, on the two sciences now called kinematics and strength of materials.

• Henri Bergson
  Henri-Louis Bergson (French pronunciation: [bɛʁksɔn] 18 October 1859 – 4 January 1941) was a major French philosopher, influential especially in the first half of the 20th century. Bergson convinced many thinkers that immediate experience and intuition are more significant than rationalism and science for understanding reality.
  He was awarded the 1927 Nobel Prize in Literature "in recognition of his rich and vitalizing ideas and the brilliant skill with which they have been presented".
  Bergson was born in the Rue Lamartine in Paris, not far from the Palais Garnier (the old Paris opera house) in 1859 (the year in which France emerged as a victor in the Second Italian War of Independence, and in the month before the publication of Charles Darwin's On the Origin of Species). His father, the pianist Michał Bergson, was of a Polish Jewish family background (originally bearing the name Bereksohn). His mother, Katherine Levison, daughter of a Yorkshire doctor, was from an English and Irish Jewish background. The Bereksohns were a famous^{[citation needed]} Jewish entrepreneurial family of Polish descent. Henri Bergson's great-great-grandfather, Szmul Jakubowicz Sonnenberg, called Zbytkower, was a prominent banker and a protégé of Stanisław August Poniatowski, King of Poland from 1764 to 1795.

  Henri Poincaré
  Jules Henri Poincaré (29 April 1854 – 17 July 1912) (French pronunciation: [ˈʒyl ɑ̃ˈʁi pwɛ̃nkaˈʁe]) was a French mathematician, theoretical physicist, engineer, and a philosopher of science. He is often described as a polymath, and in mathematics as The Last Universalist, since he excelled in all fields of the discipline as it existed during his lifetime.
  As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. He was responsible for formulating the Poincaré conjecture, which was one of the most famous unsolved problems in mathematics until it was solved in 2002–2003. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory. He is also considered to be one of the founders of the field of topology.
  Poincaré made clear importance of paying attention to the invariance of laws of physics under different transformations, and was the first to present the Lorentz transformations in their modern symmetrical form. Poincaré discovered the remaining relativistic velocity transformations and recorded them in a letter to Dutch physicist Hendrik Lorentz (1853–1928) in 1905. Thus he obtained perfect invariance of all of Maxwell's equations, an important step in the formulation of the theory of special relativity.

  Herbert Spencer
  Herbert Spencer (27 April 1820 – 8 December 1903) was an English philosopher, biologist, sociologist, and prominent classical liberal political theorist of the Victorian era.
  Spencer developed an all-embracing conception of evolution as the progressive development of the physical world, biological organisms, the human mind, and human culture and societies. He was "an enthusiastic exponent of evolution" and even "wrote about evolution before Darwin did." As a polymath, he contributed to a wide range of subjects, including ethics, religion, anthropology, economics, political theory, philosophy, biology, sociology, and psychology. During his lifetime he achieved tremendous authority, mainly in English-speaking academia. "The only other English philosopher to have achieved anything like such widespread popularity was Bertrand Russell, and that was in the 20th century." Spencer was "the single most famous European intellectual in the closing decades of the nineteenth century" but his influence declined sharply after 1900; "Who now reads Spencer?" asked Talcott Parsons in 1937.

  Hippocrates
  Hippocrates of Cos or Hippokrates of Kos (Ancient Greek: Ἱπποκράτης; Hippokrátēs; c. 460 BC – c. 370 BC) was an ancient Greek physician of the Age of Pericles (Classical Athens), and is considered one of the most outstanding figures in the history of medicine. He is referred to as the father of Western medicine in recognition of his lasting contributions to the field as the founder of the Hippocratic School of Medicine. This intellectual school revolutionized medicine in ancient Greece, establishing it as a discipline distinct from other fields that it had traditionally been associated with (notably theurgy and philosophy), thus establishing medicine as a profession.
  However, the achievements of the writers of the Corpus, the practitioners of Hippocratic medicine, and the actions of Hippocrates himself are often commingled; thus very little is known about what Hippocrates actually thought, wrote, and did. Hippocrates is commonly portrayed as the paragon of the ancient physician, credited with coining the Hippocratic Oath, still relevant and in use today. He is also credited with greatly advancing the systematic study of clinical medicine, summing up the medical knowledge of previous schools, and prescribing practices for physicians through the Hippocratic Corpus and other works.

  Dr Homer William Smith (January 2, 1895 – March 25, 1962) was an American physiologist and an advocate for science, who spent most of his career at New York University School of Medicine.[1] His research work focused on the kidney and he discovered inulin at the same time as A.N. Richards. Dr. Smith authored several books including From Fish to Philosopher, Man and His Gods,[2] and The Kidney: Structure and function in health and disease.
  Homer Smith's elegant experiments on the kidney in the 1930s proved beyond any doubt that it operated according to physical principles, both as a filter and a secretory organ, eliminating the last vestige of Vitalism in physiology.
  He also served on the board of trustees of Science Service, now known as Society for Science & the Public, from 1952-1955.
  Dr. Smith is survived by his son, Homer Wilson Smith.

  Hugh of Saint Victor
  Hugh of Saint Victor (c. 1096 – 11 February 1141) was born perhaps in France, or more probably in Saxony. His origins and early life are rather obscure. He studied and taught at the Augustinian Abbey of Saint Victor in Paris after which he is named. His writings include works of theology, mysticism, philosophy and the arts. Appointed a canon of the Victorines around the turn of the twelfth century.
  The early Didascalion was an elementary, encyclopedic approach to God and Christ, in which Hugh avoided controversial subjects and focused on what he took to be commonplaces of Catholic Christianity. In it he outlined three types of philosophy or "science" [scientia] that can help mortals improve themselves and advance toward God: theoretical philosophy (theology, mathematics, physics) provides them with truth, practical philosophy (ethics, economics, politics) aids them in becoming virtuous and prudent, and "mechanical" or "illiberal" philosophy (e.g., carpentry, agriculture, medicine) yields physical benefits. A fourth philosophy, logic, is preparatory to the others and exists to ensure clear and proper conclusions in them. Hugh's deeply mystical bent did not prevent him from seeing philosophy as a useful tool for understanding the divine, or from using it to argue on behalf of faith.

  Immanuel Kant
  Immanuel Kant (German pronunciation: [ɪˈmaːnu̯eːl ˈkant]; 22 April 1724 – 12 February 1804) was a German philosopher from Königsberg (today Kaliningrad of Russia), who researched, lectured, and wrote on philosophy and anthropology during the Enlightenment at the end of the 18th century. At the time, there were major successes and advances in the sciences (for example, Isaac Newton, Carl Friedrich Gauss, and Robert Boyle) applying reason and logic.
  Kant’s major work, the Critique of Pure Reason (Kritik der reinen Vernunft, 1781), aimed to unite reason with experience to move beyond what he took to be failures of traditional philosophy and metaphysics. He hoped to end an age of speculation where objects outside experience were used to support what he saw as futile theories, while opposing the skepticism of thinkers such as Descartes, Berkeley and Hume.
  He stated:
  Kant proposed a ‘Copernican Revolution’ in reverse, saying that:
  Kant published other important works on ethics, religion, law, aesthetics, astronomy, and history. These included the Critique of Practical Reason (Kritik der praktischen Vernunft, 1788) and the Metaphysics of Morals (Die Metaphysik der Sitten, 1797), which dealt with ethics. And the Critique of Judgment (Kritik der Urteilskraft, 1790), which looks at aesthetics and teleology. He aimed to resolve disputes between empirical and rationalist approaches. The former asserted that all knowledge comes through experience; the latter maintained that reason and innate ideas were prior. Kant argued that experience is purely subjective without first being processed by pure reason. He also said that using reason without applying it to experience only leads to theoretical illusions. The free and proper exercise of reason by the individual was both a theme of the Enlightenment, and of Kant's approaches to the various problems of philosophy.

  Imre Lakatos
  Imre Lakatos (November 9, 1922 – February 2, 1974) was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its 'methodology of proofs and refutations' in its pre-axiomatic stages of development, and also for introducing the concept of the 'research programme' in his methodology of scientific research programmes.
  Lakatos was born Imre (Avrum) Lipschitz to a Jewish family in Debrecen, Hungary in 1922. He received a degree in mathematics, physics, and philosophy from the University of Debrecen in 1944. He avoided Nazi persecution of Jews by changing his name to Imre Molnár. His mother and grandmother died in Auschwitz. He became an active communist during the Second World War. He changed his last name once again to Lakatos (Locksmith) in honor of Géza Lakatos.
  After the war, from 1947 he worked as a senior official in the Hungarian ministry of education. He also continued his education with a PhD at Debrecen University awarded in 1948, and also attended György Lukács's weekly Wednesday afternoon private seminars. He also studied at the Moscow State University under the supervision of Sofya Yanovskaya in 1949. When he returned, however, he found himself on the losing side of internal arguments within the Hungarian communist party and was imprisoned on charges of revisionism from 1950 to 1953. More of Lakatos' activities in Hungary after World War II have recently become known.

His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.

  Loeb was educated at the universities of Berlin, Munich, and Strasburg (M.D. 1884). He took postgraduate courses at the universities of Strasburg and Berlin, and in 1886 became assistant at the physiological institute of the University of Würzburg, remaining there till 1888. In a similar capacity, he then went to Strasburg University. During his vacations he pursued biological researches, at Kiel in 1888, and at Naples in 1889 and 1890.
  In 1892 he was called to the University of Chicago as assistant professor of physiology and experimental biology, becoming associate professor in 1895, and professor of physiology in 1899. John B. Watson "father of Behaviorism" was a student of Loebs neurology classes at University of Chicago. In 1902 he was called to fill a similar chair at the University of California.
  In 1910 Loeb moved to the Rockefeller Institute for Medical Research in New York, where he headed a department created for him. He remained at Rockefeller (now Rockefeller University) until his death. Throughout most of these years Loeb spent his summers at the Marine Biological Laboratory in Woods Hole, Massachusetts, performing experiments on various marine invertebrates. It was there that Jacques Loeb performed his most famous experiment, on artificial parthenogenesis. Loeb was able to cause the eggs of sea urchins to begin embryonic development without sperm. This was achieved by slight chemical modifications of the water in which the eggs were kept, which served as the stimulus for the development to begin.

For the last 20 years, he has been a doctor in general practice. Le Fanu is also a medical journalist and has written articles and reviews both for medical journals such as the British Medical Journal and for magazines, and weekly columns in the Daily Telegraph and the Sunday Telegraph, for which he is best known.
  Le Fanu is also an author. His books include The Rise and Fall of Modern Medicine, which won the Los Angeles Prize Book Award in 2001, and Why Us?: How Science Rediscovered the Mystery of Ourselves (2009).
  In his book The Rise and Fall of Modern Medicine, Le Fanu claims that from the 1930s until the mid 1970s was the "Golden Age" for medicine, due to smaller groups of researchers working with rudimentary technology and without modern sophisticated biological knowledge and that since then "the fall of medicine" has occurred. He sees this due to the number of cures declining at the same time as new scientific knowledge of human biology was improving. He further claims that whilst industrialised medicine has improved because of technological advances, at the same time the costs have increased hugely. Other reasons he lists for the fall of medicine include his argument that medicine has become too centred on a movement he calls "The New Genetics"; he further links the fall of medicine to the "social theory" of public health, such as the work of Ancel Keys in the 1950s.

In addition to holding various cabinet posts, he served as Prime Minister of the Union of South Africa from 1919 until 1924 and from 1939 until 1948. He served in the First World War and as a British field marshal in the Second World War.
  He led commandos in the Second Boer War for the Transvaal. During the First World War, he led the armies of South Africa against Germany, capturing German South-West Africa and commanding the British Army in East Africa. From 1917 to 1919, he was also one of five members of the British War Cabinet, helping to create the Royal Air Force. He became a field marshal in the British Army in 1941, and served in the Imperial War Cabinet under Winston Churchill. He was the only person to sign the peace treaties ending both the First and Second World Wars.
  One of his greatest international accomplishments was the establishment of the League of Nations, the exact design and implementation of which relied upon Smuts. He later urged the formation of a new international organisation for peace: the UN. Smuts wrote the preamble to the United Nations Charter, and was the only person to sign the charters of both the League of Nations and the UN. He sought to redefine the relationship between the United Kingdom and her colonies, helping to establish the British Commonwealth, as it was known at the time. However, in 1946 the General Assembly requested the Smuts government to take measures to bring the treatment of Indians in South Africa into line with the provisions of the United Nations Charter.

Dewey was an important early developer of the philosophy of pragmatism and one of the founders of functional psychology. He was a major representative of progressive education and liberalism.
  Although Dewey is known best for his publications concerning education, he also wrote about many other topics, including experience, nature, art, logic, inquiry, democracy, and ethics.
  In his advocacy of democracy, Dewey considered two fundamental elements—schools and civil society—as being major topics needing attention and reconstruction to encourage experimental intelligence and plurality. Dewey asserted that complete democracy was to be obtained not just by extending voting rights but also by ensuring that there exists a fully formed public opinion, accomplished by effective communication among citizens, experts, and politicians, with the latter being accountable for the policies they adopt.^{[citation needed]}

  John Scott Haldane CH FRS (May 3, 1860 – March 14/March 15, 1936) was a Scottish physiologist famous for intrepid self-experimenting which led to many important discoveries about the human body and the nature of gases. He also used his son J. B. S. Haldane as a guinea pig, even when he was quite young. John Haldane locked himself in sealed chambers breathing lethal cocktails of gases while recording their effect on his mind and body. He visited the scenes of many mining disasters and investigated their causes. When the Germans used poison gas in World War I Haldane went to the front at the request of British secretary of state, Lord Kitchener and attempted to identify the gases being used. One outcome of this was his invention of the first gas mask [1]. His son, J.B.S. Haldane became equally famous, both by extending his father's interest in diving and as a key figure in the development of the modern evolutionary synthesis.
  Haldane was born in Edinburgh. He was the son of Robert Haldane and the grandson of the Scottish evangelist James Alexander Haldane. His mother was Mary Elizabeth Burdon-Sanderson, the daughter of Richard Burdon-Sanderson and the granddaughter of Sir Thomas Burdon. His maternal uncle was the physiologist John Scott Burdon-Sanderson. He was the brother of Elizabeth Haldane, William Stowell Haldane and Richard Burdon Haldane, 1st Viscount Haldane.

  John Stuart Mill, FRSE (20 May 1806 – 8 May 1873) was a British philosopher, political economist and civil servant. He was an influential contributor to social theory, political theory, and political economy. He has been called "the most influential English-speaking philosopher of the nineteenth century". Mill's conception of liberty justified the freedom of the individual in opposition to unlimited state control. He was a proponent of utilitarianism, an ethical theory developed by Jeremy Bentham. Hoping to remedy the problems found in an inductive approach to science, such as confirmation bias, he clearly set forth the premises of falsification as the key component in the scientific method. Mill was also a Member of Parliament and an important figure in liberal political philosophy.
  John Stuart Mill was born on Rodney Street in the Pentonville area of London, the eldest son of the Scottish philosopher, historian and economist James Mill, and Harriet Burrow. John Stuart was educated by his father, with the advice and assistance of Jeremy Bentham and Francis Place. He was given an extremely rigorous upbringing, and was deliberately shielded from association with children his own age other than his siblings. His father, a follower of Bentham and an adherent of associationism, had as his explicit aim to create a genius intellect that would carry on the cause of utilitarianism and its implementation after he and Bentham had died.

He is perhaps best known for his theory on the concepts of 'communicative rationality' and the 'public sphere'. His work focuses on the foundations of social theory and epistemology, the analysis of advanced capitalistic societies and democracy, the rule of law in a critical social-evolutionary context, and contemporary politics, particularly German politics. Habermas's theoretical system is devoted to revealing the possibility of reason, emancipation, and rational-critical communication latent in modern institutions and in the human capacity to deliberate and pursue rational interests. Habermas is known for his work on the concept of modernity, particularly with respect to the discussions of "rationalization" originally set forth by Max Weber. While influenced by American pragmatism, action theory, and even poststructuralism, many of the central tenets of Habermas' thought remain broadly Marxist in nature. Global polls identified him as one of the leading intellectuals of the present day.

  In 1911 he founded the world's first university statistics department at University College London. He was a proponent of eugenics, and a protégé and biographer of Sir Francis Galton.
  A sesquicentenary conference was held in London on 23 March 2007, to celebrate the 150th anniversary of his birth.
  Carl Pearson, later known as Karl Pearson (1857–1936), was born to William Pearson and Fanny Smith, who had three children, Aurthur, Carl (Karl) and Amy. William Pearson also sired an illegitimate son, Frederick Mockett.
  Pearson's mother, Fanny Pearson née Smith, came from a family of master mariners who sailed their own ships from Hull; his father read law at Edinburgh and was a successful barrister and Queen's Counsel (QC). William Pearson's father's family came from the North Riding of Yorkshire.
  "Carl Pearson" inadvertently became "Karl Pearson" when he enrolled at the University of Heidelberg in 1879, which changed the spelling. He used both variants of his name until 1884 when he finally adopted Karl — supposedly also after Karl Marx^{[citation needed]}, though some argue otherwise.

  Sir Karl Raimund Popper, CH FRSFBA (28 July 1902 – 17 September 1994) was an Austro-Britishphilosopher and professor at the London School of Economics. He is generally regarded as one of the greatest philosophers of science of the 20th century; he also wrote extensively on social and political philosophy.
  Popper is known for his attempt to repudiate the classical observationalist/inductivist form of scientific method in favour of empirical falsification. He is also known for his opposition to the classical justificationist account of knowledge which he replaced with critical rationalism, "the first non justificational philosophy of criticism in the history of philosophy". In political discourse, he is known for his vigorous defence of liberal democracy and the principles of social criticism that he came to believe made a flourishing "open society" possible.
  Karl Popper was born in Vienna (then in Austria-Hungary) in 1902, to upper middle-class parents. All of Karl Popper's grandparents were Jewish, but the Popper family converted to Lutheranism before Karl was born. Karl's father Simon Siegmund Carl Popper was a lawyer from Bohemia, and mother Jenny Schiff was of Silesian and Hungarian descent. After establishing themselves in Vienna, the Poppers made a rapid social climb in Viennese society: Simon Siegmund Carl became a legal partner^{[clarification needed]} of Vienna's liberal mayor Raimond Grübl and, after his death in 1898, took over the firm (Karl received his middle name from the mayor).

  Ken Wilber was born on January 31, 1949 in Oklahoma City, Oklahoma. In 1967, he enrolled as a pre-med student at Duke University,. He became inspired, like many of his generation, by Eastern literature, particularly the Tao Te Ching. He left Duke and enrolled in the University of Nebraska at Lincoln, completing a bachelor's degree in chemistry and biology and a Master's degree in biochemistry.
  In 1973, Wilber completed his first book, The Spectrum of Consciousness, in which he sought to integrate knowledge from disparate fields. After rejections by more than twenty publishers it was finally accepted in 1977 by Quest Books, and he spent a year giving lectures and workshops before going back to writing. He also helped to launch the journal ReVision in 1978.

• Larry Laudan
  Larry Laudan (b. Austin, Texas, 1941) is a contemporary philosopher of science and epistemologist. He has strongly criticized the traditions of positivism, realism, and relativism, and he has defended a view of science as a privileged and progressive institution against popular challenges. Laudan's philosophical view of "research traditions" is seen as an important alternative to Imre Lakatos's "research programs."
  His most important contributions to the philosophy of science can be found in his book Progress and its Problems (1977) while acting as chair of the history and philosophy of science department at the University of Pittsburgh. Laudan charges philosophers of science with paying lip service to the view that “science is fundamentally a problem-solving activity” without taking seriously the view's implications for the history of science and its philosophy, and without questioning certain issues in the historiography and methodology of science. Against empiricism, which is represented by Karl Popper, and "revolutionism," represented by Thomas Kuhn, Laudan maintained in Progress and its Problems that science is an evolving process that accumulates more empirically validated evidence while solving conceptual anomalies at the same time. Mere evidence collecting or empirical confirmation does not constitute the true mechanism of scientific advancement; conceptual resolution and comparison of the solutions of anomalies provided by various theories form an indispensable part of the evolution of science.

  Louis Pasteur
  Louis Pasteur ( /ˈluːi pæˈstɜr/, French: [lwi pastœʁ]; December 27, 1822 – September 28, 1895) was a French chemist and microbiologist born in Dole. He is remembered for his remarkable breakthroughs in the causes and preventions of diseases. His discoveries reduced mortality from puerperal fever, and he created the first vaccines for rabies and anthrax. His experiments supported the germ theory of disease. He was best known to the general public for inventing a method to stop milk and wine from causing sickness, a process that came to be called pasteurization. He is regarded as one of the three main founders of microbiology, together with Ferdinand Cohn and Robert Koch. Pasteur also made many discoveries in the field of chemistry, most notably the molecular basis for the asymmetry of certain crystals. His body lies beneath the Institute Pasteur in Paris in a spectacular vault covered in depictions of his accomplishments in Byzantine mosaics.
  Louis Pasteur was born on December 27, 1822, in Dole in the Jura region of France, into the family of a poor tanner. Louis grew up in the town of Arbois. He gained degrees in Letters and in Mathematical Sciences before entering the École Normale Supérieure, an elite college. After serving briefly as professor of physics at Dijon Lycée in 1848, he became professor of chemistry at the University of Strasbourg, where he met and courted Marie Laurent, daughter of the university's rector, in 1849. They were married on May 29, 1849, and together had five children, only two of whom survived to adulthood; the other three died of typhoid. These personal tragedies inspired Pasteur to try to find cures for diseases such as typhoid.

  Marcellin Berthelot
  Pierre Eugène Marcellin Berthelot (25 October 1827 – 18 March 1907) was a French chemist and politician noted for the Thomsen-Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances and disproved the theory of vitalism. He is considered as one of the greatest chemists of all time.
  He was born in Paris, the son of a doctor. After doing well at school in history and philosophy, he became a scientist.
  The fundamental conception that underlay all Berthelot's chemical work was that all chemical phenomena depend on the action of physical forces which can be determined and measured. When he began his active career it was generally believed that, although some instances of the synthetic production of organic substances had been observed, on the whole organic chemistry remained an analytical science and could not become a constructive one, because the formation of the substances with which it deals required the intervention of vital activity in some shape. To this attitude he offered uncompromising opposition, and by the synthetic production of numerous hydrocarbons, natural fats, sugars and other bodies he proved that organic compounds can be formed by ordinary methods of chemical manipulation and obey the same principles as inorganic substances, thus exhibiting the "creative character in virtue of which chemistry actually realizes the abstract conceptions of its theories and classifications—a prerogative so far possessed neither by the natural nor by the historical sciences."

  Marcello Malpighi
  Marcello Malpighi (10 March 1628 – 29 November 1694) was an Italian doctor, who gave his name to several physiological features, like the Malpighian tubule system.
  Malpighi was born on March 10, 1628 at Crevalcore near Bologna, Italy. The son of well-to-do parents, Malpighi was educated in his native city, entering the University of Bologna at the age of 17. In a posthumous work delivered and dedicated to the Royal Society in London in 1697, Malpighi says he completed his grammatical studies in 1645, at which point he began to apply himself to the study of Peripatetic Philosophy. He completed these studies about 1649, where at the persuasion of his mother Frances Natalis he began to study physics. When his parents and grandmother became ill, he returned to his family home near Bologna to care for them.
  In 1653, his father, mother, and grandmother being dead, Malpighi left his family villa and returned to the University of Bologna to study Anatomy. In 1656 he was made a reader at Bologna, and then a professor of physics at Pisa, where he began to abandon the disputative method of learning and apply himself to a more experimental method of research. Based on this research, he wrote some Dialogues against the Peripatetics and Galenists (those who followed the precepts of Galen), which were destroyed when his house burned down. Weary of philosophical disputation, in 1660, Malpighi returned to Bologna and dedicated himself to the study of anatomy. He subsequently discovered a new structure of the lungs which led him to several disputes with the learned medical men of the times. In 1662, he was made a professor of Physic at the Academy of Messina.

  Molière
  Jean-Baptiste Poquelin, known by his stage name Molière, (French pronunciation: [mo.ljɛːʁ]; baptised January 15, 1622 – February 17, 1673) was a French playwright and actor who is considered to be one of the greatest masters of comedy in Western literature. Among Molière's best-known works are Le Misanthrope (The Misanthrope), L'École des femmes (The School for Wives), Tartuffe ou L'Imposteur, (Tartuffe or the Hypocrite), L'Avare (The Miser), Le Malade imaginaire (The Imaginary Invalid), and Le Bourgeois Gentilhomme (The Bourgeois Gentleman).
  Born into a prosperous family and having studied at the Collège de Clermont (now Lycée Louis-le-Grand), Molière was well suited to begin a life in the theatre. Thirteen years as an itinerant actor helped him polish his comic abilities while he began writing, combining Commedia dell'arte elements with the more refined French comedy.
  Through the patronage of a few aristocrats, including Philippe I, Duke of Orléans – the brother of Louis XIV – Molière procured a command performance before the King at the Louvre. Performing a classic play by Pierre Corneille and a farce of his own, Le Docteur amoureux (The Doctor in Love), Molière was granted the use of salle du Petit-Bourbon near the Louvre, a spacious room appointed for theatrical performances. Later, Molière was granted the use of the Palais-Royal. In both locations he found success among the Parisians with plays such as Les Précieuses ridicules (The Affected Ladies), L'École des maris (The School for Husbands) and L'École des femmes (The School for Wives). This royal favor brought a royal pension to his troupe and the title "Troupe du Roi" (The King's Troupe). Molière continued as the official author of court entertainments.

  Niels Bohr
  Niels Henrik David Bohr (Danish pronunciation: [ˈniːls ˈboɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. Bohr mentored and collaborated with many of the top physicists of the century at his institute in Copenhagen. He was part of the British team of physicists working on the Manhattan Project. Bohr married Margrethe Nørlund in 1912, and one of their sons, Aage Bohr, grew up to be an important physicist who in 1975 also received the Nobel Prize. Bohr has been described as one of the most influential scientists of the 20th century.
  Bohr was born in Copenhagen, Denmark, in 1885. His father, Christian Bohr, was professor of physiology at the University of Copenhagen (it is his name which is given to the Bohr shift or Bohr effect), while his mother, Ellen Adler Bohr, came from a wealthy Jewish family prominent in Danish banking and parliamentary circles (in 1891, Bohr was baptized a Lutheran, his father's religion).Despite having a religious background, he later became an atheist.His brother was Harald Bohr, a mathematician and Olympic footballer who played on the Danish national team. Niels Bohr was a passionate footballer as well, and the two brothers played a number of matches for the Copenhagen-based Akademisk Boldklub, with Niels in goal.

  Oscar Hertwig
  Oscar Hertwig (21 April 1849, Friedberg – 25 October 1922, Berlin) was a German zoologist and professor, who also wrote about the theory of evolution circa 1916, over 55 years after Charles Darwin's book The Origin of Species. He was the elder brother of zoologist-professor Richard Hertwig (1850–1937).
  The Hertwig brothers were the most eminent scholars of Ernst Haeckel (and Carl Gegenbaur) from the University of Jena. They were independent of Haeckel's philosophical speculations but took his ideas in a positive way to widen their concepts in zoology. Initially, between 1879–1883, they performed embryological studies, especially on the theory of the coelom (1881), the fluid-filled body cavity. These problems were based on the phylogenetic theorems of Haeckel, i.e. the biogenic theory (German = biogenetisches Grundgesetz), and the "gastraea theory".
  Within 10 years, the two brothers moved apart to the north and south of Germany. Oscar Hertwig later became a professor of anatomy in 1888 in Berlin; however, Richard Hertwig had moved 3 years prior, becoming a professor of zoology in Munich from 1885–1925, at Ludwig Maximilians Universität, where he served the last 40 years of his 50-year career as a professor at 4 universities.

• Otto Neurath
  Otto Neurath (Vienna, December 10, 1882 - Oxford, December 22, 1945) was an Austrian philosopher of science, sociologist, and political economist. Before he was to flee his native country in 1934, Neurath was one of the leading figures of the Vienna Circle.
  Neurath was born in Vienna, the son of Wilhelm Neurath (1840–1901), a well-known political economist at the time. He studied mathematics in Vienna and gained his Ph.D. in the department of Political Science and Statistics at the University of Berlin.
  He married Anna Schapire in 1907. She died as a result of childbirth (Paul Neurath) in 1911, and he married a close friend, the mathematician and philosopher Olga Hahn. Perhaps because of Olga's blindness and then because of the outbreak of war, his son, Paul Neurath was sent to a children's home outside Vienna, where Neurath's mother lived, and returned to live with his father and Olga when he was nine years old.
  Neurath taught political economy at the Neue Wiener Handelsakademie (New College of Commerce, Vienna) until war broke out. Subsequently he became director of the Deutsches Kriegwirtschaftsmuseum (German Museum of War Economy, later the Deutsches Wirtschaftmuseum) at Leipzig. Wolfgang Schumann, known from the Dürerbund for which Neurath had written many articles, urged him to work out a plan for socialization. Neurath joined the German Social Democratic Party in 1918-19 and ran an office for central economic planning in Munich. When the Bavarian Soviet Republic was defeated, Neurath was imprisoned but returned to Austria after intervention from the Austrian government. While in prison he wrote "Anti-Spengler", a critical attack on Oswald Spengler's "Decline of the West".

He lived a peripatetic life, living at various times in England, the United States, New Zealand, Italy, Germany, and finally Switzerland. His major works include Against Method (published in 1975), Science in a Free Society (published in 1978) and Farewell to Reason (a collection of papers published in 1987). Feyerabend became famous for his purportedly anarchistic view of science and his rejection of the existence of universal methodological rules. He is an influential figure in the philosophy of science, and also in the sociology of scientific knowledge.

  Paul Haeberlin (February 17, 1878, Kesswil – September 29, 1960, Basel) was a Swiss philosopher who at different times in his career took the standpoint that either religion or theoretical knowledge was the answer to human problems. He always gave philosophy an important role, but religion was to him the only way man could understand his real position in existence. Haeberlin made contributions to characterology and psychotherapeutics, and was especially successful in treating psychopathic youth and teens. Made a full professor of philosophy, psychology and pedagogics at the University of Basel.

  Pierre Duhem
  Pierre Maurice Marie Duhem ([pjˈɛʁ moʁˈis maʁˈi dyˈɛm] ( listen); 9 June 1861 – 14 September 1916) was a French physicist, mathematician and philosopher of science, best known for his writings on the indeterminacy of experimental criteria and on scientific development in the Middle Ages. Duhem also made major contributions to the science of his day, particularly in the fields of hydrodynamics, elasticity, and thermodynamics.
  Duhem's views on the philosophy of science are explicated in The Aim and Structure of Physical Theory. In this work, he opposed Newton's statement that the Principia's law of universal mutual gravitation was deduced from 'phenomena', including Kepler's second and third laws. Newton's claims in this regard had already been attacked by critical proof-analyses of the German logician Leibniz and then most famously by Immanuel Kant, following Hume's logical critique of induction. But the novelty of Duhem's work was his proposal that Newton's theory of universal mutual gravity flatly contradicted Kepler's Laws of planetary motion because the interplanetary mutual gravitational perturbations caused deviations from Keplerian orbits. Since no proposition can be validly logically deduced from any it contradicts, according to Duhem, Newton must not have logically deduced his law of gravitation directly from Kepler's Laws.

  Pierre Gassendi
  Pierre Gassendi (January 22, 1592 – October 24, 1655) was a French philosopher, priest, scientist, astronomer, and mathematician. With a church position in south-east France, he also spent much time in Paris, where he was a leader of a group of free-thinking intellectuals. He was also an active observational scientist, publishing the first data on the transit of Mercury in 1631. The lunar crater Gassendi is named after him.
  He wrote numerous philosophical works, and some of the positions he worked out are considered significant, finding a way between scepticism and dogmatism. Richard Popkin indicates that Gassendi was one of the first thinkers to formulate the modern "scientific outlook", of moderated scepticism and empiricism. He clashed with his contemporary Descartes on the possibility of certain knowledge. His best known intellectual project attempted to reconcile Epicurean atomism with Christianity.
  Gassendi was born at Champtercier, near Digne, in France. A youthful prodigy, at a very early age he showed academic potential and attended the college at Digne, where he displayed a particular aptitude for languages and mathematics. Soon afterwards he entered the University of Aix-en-Provence, to study philosophy under Philibert Fesaye. In 1612 the college of Digne called him to lecture on theology. Four years later he received the degree of Doctor of Theology at Avignon, and in 1617 he took holy orders. In the same year he answered a call to the chair of philosophy at Aix-en-Provence University, and seems gradually to have withdrawn from theology.

  Plato
  Plato ( /ˈpleɪtoʊ/; Greek: Πλάτων, Plátōn, "broad"; 424/423 BC – 348/347 BC) was a Classical Greek philosopher, mathematician, student of Socrates, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of Western philosophy and science. In the words of A. N. Whitehead:
  The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. I do not mean the systematic scheme of thought which scholars have doubtfully extracted from his writings. I allude to the wealth of general ideas scattered through them.
  Plato's sophistication as a writer is evident in his Socratic dialogues; thirty-six dialogues and thirteen letters have been ascribed to him. Plato's writings have been published in several fashions; this has led to several conventions regarding the naming and referencing of Plato's texts. Plato's dialogues have been used to teach a range of subjects, including philosophy, logic, ethics, rhetoric, and mathematics.

  Raphael
  Raffaello Sanzio da Urbino (April 6 or March 28, 1483 – April 6, 1520), better known simply as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form and ease of composition and for its visual achievement of the Neoplatonic ideal of human grandeur. Together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period.
  Raphael was enormously productive, running an unusually large workshop, and despite his death at 37, a large body of his work remains. Many of his works are found in the Apostolic Palace of The Vatican, where the frescoed Raphael Rooms were the central, and the largest, work of his career. The best known work is The School of Athens in the Vatican Stanza della Segnatura. After his early years in Rome much of his work was self-designed, but for the most part executed by the workshop from his drawings, with considerable loss of quality. He was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking. After his death, the influence of his great rival Michelangelo was more widespread until the 18th and 19th centuries, when Raphael's more serene and harmonious qualities were again regarded as the highest models. His career falls naturally into three phases and three styles, first described by Giorgio Vasari: his early years in Umbria, then a period of about four years (from 1504–1508) absorbing the artistic traditions of Florence, followed by his last hectic and triumphant twelve years in Rome, working for two Popes and their close associates.

  René Descartes
  René Descartes (French pronunciation: [ʁəne dekaʁt]; Latinized form: Renatus Cartesius; adjectival form: "Cartesian"; 31 March 1596 – 11 February 1650) was a French philosopher, mathematician, and writer who spent most of his adult life in the Dutch Republic. He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his Meditations on First Philosophy continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system — allowing algebraic equations to be expressed as geometric shapes in a two-dimensional coordinate system — was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution and has been described as an example of genius.

  Robert Kilwardby
  Robert Kilwardby (c. 1215–11 September 1279) was an Archbishop of Canterbury in England and as well as a cardinal.
  Kilwardby studied at the University of Paris, then was a teacher of grammar and logic there. He then joined the Dominican Order and studied theology, and became regent at Oxford University before 1261, probably by 1245. He was named provincial prior of the Dominicans for England in 1261, and in October 1272 Pope Gregory X appointed him as Archbishop of Canterbury to end a disupte over the election. Kilwardby was provided to the archbishopric on 11 October 1272, given the temporalities on 12 December 1272, and consecrated on 26 February 1273.
  Kilwardby crowned Edward I and his wife Eleanor as king and queen of England in August 1274, but otherwise took little part in politics. He instead concentrated on his ecclesiastical duties, including charity to the poor and donating to the Dominicans.
  In 1278 Pope Nicholas III named Kilwardby Cardinal Bishop of Porto and Santa Rufina. He then resigned Canterbury and left England, taking with him papers, registers and documents belonging to the see. He also left the see deep in debt again, after his predecessor had cleared the debt. He died in Italy in 1279 and was buried in the Dominican convent in Viterbo, Italy. While in theory this was a promotion, probably it was not, as the pope was unhappy with Kilwardy's support of efforts to resist the payment of papal revenues and with the lack of effort towards the reforms demanded at the Second Council of Lyon in 1274.

  Roger Bacon
  Roger Bacon, O.F.M. (c. 1214–1294), (scholastic accolade Doctor Mirabilis, meaning "wonderful teacher"), was an English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empirical methods. He is sometimes credited, mainly starting in the 19th century, as one of the earliest European advocates of the modern scientific method inspired by the works of Aristotle and later pseudo-Aristotelian works, like the works of Muslim scientist Alhazen. However, more recent reevaluations emphasize that he was essentially a medieval thinker, with much of his "experimental" knowledge obtained from books, in the scholastic tradition. A survey of the reception of Bacon's work over centuries found that it often reflects the concerns and controversies central to the receivers.
  Roger Bacon was born in Ilchester in Somerset, England, possibly in 1213 or 1214 at the Ilchester Friary. The only source for his date of birth is his statement in the Opus Tertium, written in 1267, that "forty years have passed since I first learned the alphabet". The 1214 birth date assumes he was not being literal, and may have meant 40 years had passed since he matriculated at Oxford at the age of 13. If he had been literal, his birth date was more likely to have been around 1220/1222. In the same passage he reports that for all but two of those forty years he had always been engaged in study. His family appears to have been well-off, but, during the stormy reign of Henry III of England, their property was despoiled and several members of the family were driven into exile.

  Rudolf Carnap (May 18, 1891 – September 14, 1970) was an influential German-born philosopher who was active in Europe before 1935 and in the United States thereafter. He was a major member of the Vienna Circle and an advocate of logical positivism.
  Carnap was born to a west German family that had been humble until his parents' generation. He began his formal education at the Barmen Gymnasium. From 1910 to 1914, he attended the University of Jena, intending to write a thesis in physics. But he also studied carefully Kant's Critique of Pure Reason during a course taught by Bruno Bauch, and was one of very few students to attend Gottlob Frege's courses in mathematical logic. After serving in the German army during World War I for three years, he was given permission to study physics at the University of Berlin, 1917–18, where Albert Einstein was a newly appointed professor. Carnap then attended the University of Jena, where he wrote a thesis defining an axiomatic theory of space and time. The physics department said it was too philosophical, and Bruno Bauch of the philosophy department said it was pure physics. Carnap then wrote another thesis, with Bauch's supervision, on the theory of space in a more orthodox Kantian style, and published as Der Raum (Space) in a supplemental issue of Kant-Studien (1922). In it he makes the clear distinction between formal, physical and perceptual (e.g., visual) spaces.

  Rupert Sheldrake
  Alfred Rupert Sheldrake (born 28 June 1942) is an English scientist and author. He is known for having proposed a non-genetic account of morphogenesis and for his research into parapsychology. His books and papers stem from his theory of morphic resonance, and cover topics such as animal and plant development and behaviour, memory, telepathy, perception and cognition in general. His publications include A New Science of Life (1981), Seven Experiments That Could Change the World (1995), Dogs That Know When Their Owners Are Coming Home (1999), and The Sense of Being Stared At (2003), The Science Delusion: Freeing the spirit of enquiry (2012).
  Sheldrake was born in Newark-on-Trent, Nottinghamshire to Doris (née Tebbutt) and Reginald Alfred Sheldrake (b.1903), a family of Methodists. His father graduated from Nottingham University with a degree in pharmacy, was also an amateur naturalist and microscopist, and encouraged his son's interest in plants and animals.
  He attended Worksop College, an Anglican boarding-school, and specialized in science. Sheldrake obtained a scholarship to study Biology at Clare College, Cambridge. He specialized in biochemistry, graduated with double-first-class honours, and won the University Botany Prize. He won a Frank Knox fellowship to study philosophy and history at Harvard University at around the time Thomas Kuhn's The Structure of Scientific Revolutions (1962) was published, which he writes informed his view on the extent to which the mechanistic theory of life is just a paradigm. He returned to Cambridge, where he obtained his Ph.D. in biochemistry.

  Samuel Hahnemann
  Christian Friedrich Samuel Hahnemann (10 April 1755 – 2 July 1843) was a German physician, known for creating an alternative form of medicine called homeopathy.
  Christian Friedrich Samuel Hahnemann was born in Meissen, Saxony near Dresden. His father, along with many other family members, was a painter and designer of porcelain, for which the town of Meissen is famous.
  As a young man, Hahnemann became proficient in a number of languages, including English, French, Italian, Greek and Latin. He eventually made a living as a translator and teacher of languages, gaining further proficiency in "Arabic, Syriac, Chaldaic and Hebrew".
  Hahnemann studied medicine for two years at Leipzig. Citing Leipzig's lack of clinical facilities, he moved to Vienna, where he studied for ten months. After one term of further study, he graduated MD at the University of Erlangen on 10 August 1779, qualifying with honors. His poverty may have forced him to choose Erlangen, as the school's fees were lower. Hahnemann's thesis was titled Conspectus adfectuum spasmodicorum aetiologicus et therapeuticus.

• Sewall Wright
  Sewall Green Wright (December 21, 1889 – March 3, 1988) was an American geneticist known for his influential work on evolutionary theory and also for his work on path analysis. With R. A. Fisher and J.B.S. Haldane, he was a founder of theoretical population genetics. He is the discoverer of the inbreeding coefficient and of methods of computing it in pedigrees. He extended this work to populations, computing the amount of inbreeding of members of populations as a result of random genetic drift, and he and Fisher pioneered methods for computing the distribution of gene frequencies among populations as a result of the interaction of natural selection, mutation, migration and genetic drift. The work of Fisher, Wright, and Haldane on theoretical population genetics was a major step in the development of the modern evolutionary synthesis of genetics with evolution. Wright also made major contributions to mammalian genetics and biochemical genetics.
  Sewall Wright was born in Melrose, Massachusetts to Philip Green Wright and Elizabeth Quincy Sewall Wright. His parents were first cousins, an interesting fact in light of Wright's later research on inbreeding. The family moved three years later after Philip accepted a teaching job at Lombard College, a Universalist college in Galesburg, Illinois.

  Sigmund Freud
  Sigmund Freud (German pronunciation: [ˈziːkmʊnt ˈfʁɔʏt]), born Sigismund Schlomo Freud (6 May 1856 – 23 September 1939), was an Austrian neurologist who founded the discipline of psychoanalysis. Freud's family and ancestry were Jewish. Freud always considered himself a Jew even though he rejected Judaism and had a critical view of religion. Freud's parents were poor, but ensured his education. Freud was an outstanding pupil in high school, and graduated the Matura with honors in 1873. Interested in philosophy as a student, Freud later turned away from it and became a neurological researcher into cerebral palsy, Aphasia and microscopic neuroanatomy.
  Freud went on to develop theories about the unconscious mind and the mechanism of repression, and established the field of verbal psychotherapy by creating psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient (or "analysand") and a psychoanalyst. Though psychoanalysis has declined as a therapeutic practice, it has helped inspire the development of many other forms of psychotherapy, some diverging from Freud's original ideas and approach. Freud postulated the existence of libido (an energy with which mental process and structures are invested), developed therapeutic techniques such as the use of free association (in which patients report their thoughts without reservation and make no attempt to concentrate while doing so), discovered the transference (the process by which patients displace on to their analysts feelings based on their experience of earlier figures in their lives) and established its central role in the analytic process, and proposed that dreams help to preserve sleep by representing as fulfilled wishes that would otherwise awake the dreamer. He was also a prolific essayist, drawing on psychoanalysis to contribute to the interpretation and critique of culture.

• Stephen Toulmin
  Stephen Edelston Toulmin (25 March 1922 - 4 December 2009) was a British philosopher, author, and educator. Influenced by Ludwig Wittgenstein, Toulmin devoted his works to the analysis of moral reasoning. Throughout his writings, he sought to develop practical arguments which can be used effectively in evaluating the ethics behind moral issues. His works were later found useful in the field of rhetoric for analyzing rhetorical arguments. The Toulmin Model of Argumentation, a diagram containing six interrelated components used for analyzing arguments, was considered his most influential work, particularly in the field of rhetoric and communication, and in computer science.
  Stephen Toulmin was born in London, England, on 25 March 1922 to Geoffrey Edelson Toulmin and Doris Holman Toulmin. He earned his Bachelor of Arts degree from King's College, Cambridge in 1942. Soon after, Toulmin was hired by the Ministry of Aircraft Production as a junior scientific officer, first at the Malvern Radar Research and Development Station and later at the Supreme Headquarters of the Allied Expeditionary Force in Germany. At the end of World War II, he returned to England to earn a Master of Arts degree in 1947 and a PhD in philosophy from Cambridge University, subsequently publishing his dissertation as An Examination of the Place of Reason in Ethics (1950). While at Cambridge, Toulmin came into contact with the Austrian philosopher Ludwig Wittgenstein, whose examination on the relationship between the uses and the meanings of language shaped much of Toulmin’s own work.

  Sándor Ferenczi
  Sándor Ferenczi (7 July 1873, Miskolc, Austria-Hungary – 22 May 1933, Budapest, Hungary) was a Hungarian psychoanalyst, a key theorist of the psychoanalytic school and a close associate of Sigmund Freud.
  Born Sándor Fränkel to Baruch Fränkel and Rosa Eibenschütz, both Polish Jews, he later magyarized his surname to Ferenczi.
  As a result of his psychiatric work, he came to believe that his patients' accounts of sexual abuse as children were truthful, having verified those accounts through other patients in the same family. This was a major reason for his eventual disputes with Sigmund Freud.
  Prior to this conclusion he was notable as a psychoanalyst for working with the most difficult of patients and for developing a theory of more active intervention than is usual for psychoanalytic practice. During the early 1920s, criticizing Freud's "classical" method of neutral interpretation, Ferenczi collaborated with Otto Rank to create a "here-and-now" psychotherapy that, through Rank's personal influence, led the American Carl Rogers to conceptualize person-centered therapy (Kramer 1995).

  Thomas Henry Huxley
  Thomas Henry Huxley PC FRS (4 May 1825 – 29 June 1895) was an English biologist (anatomist), known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution.
  Huxley's famous 1860 debate with Samuel Wilberforce was a key moment in the wider acceptance of evolution, and in his own career. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of Vestiges, he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated whether humans were closely related to apes.
  Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of Darwin. He was instrumental in developing scientific education in Britain, and fought against the more extreme versions of religious tradition.
  In 1869 Huxley coined the term 'agnostic' to describe his own views on theology, a term whose use has continued to the present day (see Thomas Henry Huxley and agnosticism).

  Thomas Hobbes
  Thomas Hobbes of Malmesbury (5 April 1588 – 4 December 1679), in some older texts Thomas Hobbs of Malmsbury, was an English philosopher, best known today for his work on political philosophy. His 1651 book Leviathan established the foundation for most of Western political philosophy from the perspective of social contract theory.
  Hobbes was a champion of absolutism for the sovereign but he also developed some of the fundamentals of European liberal thought: the right of the individual; the natural equality of all men; the artificial character of the political order (which led to the later distinction between civil society and the state); the view that all legitimate political power must be "representative" and based on the consent of the people; and a liberal interpretation of law which leaves people free to do whatever the law does not explicitly forbid.
  He was one of the founders of modern political philosophy. His understanding of humans as being matter and motion, obeying the same physical laws as other matter and motion, remains influential; and his account of human nature as self-interested cooperation, and of political communities as being based upon a "social contract" remains one of the major topics of political philosophy.

  Wilhelm Windelband
  Wilhelm Windelband (May 11, 1848, Potsdam – October 22, 1915, Heidelberg) was a German philosopher of the Baden School.
  Windelband is now mainly remembered for the terms nomothetic and idiographic, which he introduced. These have currency in psychology and other areas, though not necessarily in line with his original meanings. Windelband was a neo-Kantian who protested other neo-Kantians of his time and maintained that "to understand Kant rightly means to go beyond him". Against his positivist contemporaries, Windelband argued that philosophy should engage in humanistic dialogue with the natural sciences rather than uncritically appropriating its methodologies. His interests in psychology and cultural sciences represented an opposition to psychologism and historicism schools by a critical philosophic system.
  Windelband relied in his effort to reach beyond Kant on such philosophers as Georg Wilhelm Friedrich Hegel, Johann Friedrich Herbart and Hermann Lotze. Closely associated with Windelband was Heinrich Rickert. Windelband's disciples were not only noted philosophers, but sociologists like Max Weber and theologians like Ernst Troeltsch and Albert Schweitzer.

  Wilhelm Wundt
  Wilhelm Maximilian Wundt (16 August 1832 - 31 August 1920 in Germany) was a German physician, psychologist, physiologist, philosopher, and professor, known today as one of the founding figures of modern psychology. He is widely regarded as the "father of experimental psychology". In 1879, Wundt founded the first formal laboratory for psychological research at the University of Leipzig.
  By creating this laboratory he was able to explore the nature of religious beliefs, identify mental disorders and abnormal behavior, and find damaged parts of the brain. In doing so, he was able to establish psychology as a separate science from other topics. He also formed the first journal for psychological research in 1881.
  Asteroids 635 Vundtia and 11040 Wundt are named in his honour.
  Wundt was born at Neckarau, Baden on August 16th, 1832 (now part of Mannheim), the fourth child to parents Maximilian Wundt (a Lutheran minister), and his wife Marie Frederike. When about four years of age, Wundt's family moved to Heidelsheim which was known to be a small town. He studied from 1851 to 1856 at the University of Tübingen, University of Heidelberg, and the University of Berlin. After graduating in medicine from Heidelberg (1856), Wundt studied briefly with Johannes Peter Müller, before joining the University's staff, becoming an assistant to the physicist and physiologist Hermann von Helmholtz in 1858. There he wrote Contributions to the Theory of Sense Perception (1858–62). In 1865, he wrote a textbook about human physiology. In 1867 he became a professor in acquainting medical students with the exact physical needs for medical investigation. In 1874, he became a professor of "Inductive Philosophy" in Zurich. In 1875, he moved back to Leipzig.

  William of Ockham
  William of Ockham ( /ˈɒkəm/; also Occam, Hockham, or several other spellings; c. 1288 – c. 1348) was an English Franciscan friar and scholastic philosopher, who is believed to have been born in Ockham, a small village in Surrey. He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the fourteenth century. Although he is commonly known for Ockham's razor, the methodological principle that bears his name, William of Ockham also produced significant works on logic, physics, and theology. In the Church of England, his day of commemoration is 10 April.
  William of Ockham joined the Franciscan order at an early age. It is believed that he studied theology at the University of Oxford from 1309 to 1321, but never completed his master's degree (the usual undergraduate degree in those times). Because of this, he acquired the byname Venerabilis Inceptor, or "Worthy Beginner" (an inceptor was a student formally admitted to the ranks of teachers by the university authorities). He was also known as the Doctor Invincibilis or "Unconquerable Teacher."

  William Whewell
  William Whewell ( /ˈhjuːəl/ HEW-əl; 24 May 1794 – 6 March 1866) was an English polymath, scientist, Anglican priest, philosopher, theologian, and historian of science. He was Master of Trinity College, Cambridge.
  Whewell was born in Lancaster. His father, a carpenter, wished him to follow his trade, but his success in mathematics at Lancaster and Heversham grammar schools won him an exhibition (a type of scholarship) at Trinity College, Cambridge (1812). In 1814 he was awarded the Chancellor's Gold Medal for poetry. He was Second Wrangler in 1816, President of the Cambridge Union Society in 1817, became fellow and tutor of his college, and, in 1841, succeeded Dr Christopher Wordsworth as master. He was professor of mineralogy from 1828 to 1832 and Knightbridge Professor of Philosophy (then called "moral theology and casuistical divinity") from 1838 to 1855.
  Whewell died in Cambridge 1866 as a result of a fall from his horse.
  Full bibliographical details are given by Isaac Todhunter, W. Whewell: an Account of his Writings (2 vols., 1876). See also Life of W. Whewell, by Mrs Stair Douglas (1881).
