Sir Peter Brian Medawar, OM CBE FRS (28 February 1915 – 2 October 1987) was a Brazilian/British biologist, whose work on graft rejection and the discovery of acquired immune tolerance was fundamental to the practice of tissue and organ transplants. He was awarded the 1960 Nobel Prize in Physiology or Medicine with Sir Frank Macfarlane Burnet.
Until he was partially disabled by a cerebral infarction, Medawar was Director of the National Institute for Medical Research at Mill Hill.
Medawar was born on 28 February 1915, in Petrópolis, Brazil (a town 40 miles north of Rio de Janeiro) of a Brazilian mother and a Lebanese father. Medawar left Brazil for England in 1928, and lived there for the rest of his life.
Medawar was educated at Marlborough College and Magdalen College, Oxford, where he eventually became a Fellow.
Medawar was professor of zoology at the University of Birmingham (1947–51) and University College London (1951–62). In 1962 he was appointed director of the National Institute for Medical Research, and became professor of experimental medicine at the Royal Institution (1977–83), and president of the Royal Postgraduate Medical School (1981–87). Medawar was a scientist of great inventiveness who was interested in many other subjects including opera, philosophy and cricket.
Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.
Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.
Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.
