Year 1848 (MDCCCXLVIII) was a leap year starting on Saturday (link will display the full calendar) of the Gregorian Calendar and a leap year starting on Thursday of the 12-day slower Julian calendar. It is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most fail in their immediate aims, they significantly alter the political and philosophical landscape and have major ramifications throughout the rest of the century.

Robert Blum (10 November 1807 – 9 November 1848) was a German democratic politician, publicist, poet, publisher, revolutionist and member of the National Assembly of 1848. In his fight for a strong, unified Germany he opposed ethnocentrism and it was his strong belief that no one people should rule over another. As such he was an opponent of the Prussian occupation of Poland and was in contact with the revolutionists there. Blum was likewise a critic of both antisemitism and catholicism, supported the German Catholics and agitated for the equality of the sexes. In spite of his diplomatic immunity as a member of parliament he was illegally arrested during a stay at the hotel "Stadt London" in Vienna and murdered in a summary execution, making him a martyr of the German revolution.

Blum grew up in poverty in Cologne, the son of a failed theologian who made a poor living as a cooper. He was ten years old before he could go to school. After his schooling, he worked as a craftsman in different trades. He failed as a goldsmith's apprentice, but completed an apprenticeship as a gardener. After his journeyman's time, he returned to Cologne to work in a lamp factory. His employer put him to work at the counter since he was good at calculations. In 1829, he followed his employer to Berlin where he also continued his education. His work was interrupted by obligatory military service, and on his release, his poor circumstances obliged him to return to Cologne. There, in 1830, he worked serving in a theater company and started writing politically motivated poetry and plays. When the theater closed in the summer, he worked for a sheriff as a scribe.

Kenneth Lauren "Ken" Burns (born July 29, 1953) is an American director and producer of documentary films, known for his style of using archival footage and photographs. Among his productions are The Civil War (1990), Baseball (1994), Jazz (2001), The War (2007), The National Parks: America's Best Idea (2009) and Prohibition (2011).

Burns' documentaries have been nominated for two Academy Awards, and have won Emmy Awards, among other honors.

Ken Burns was born in 1953 in Brooklyn, New York City, New York, according to his official website, though some sources give Ann Arbor, Michigan, and some, including The New York Times, give both Brooklyn and Ann Arbor. The son of Lyla Smith (née Tupper) Burns, a biotechnician, and Robert Kyle Burns, at the time a graduate student in cultural anthropology at Columbia University, in Manhattan. Ken Burns' brother is the documentary filmmaker Ric Burns.

Burns' academic family moved frequently, and lived in Saint-Véran, France; Newark, Delaware; and Ann Arbor, where his father taught at the University of Michigan. Burns' mother was diagnosed with breast cancer when Burns was 3, and died when he was 11, a circumstance that he said helped shape his career; he credited his father-in-law, a psychologist, with a signal insight: "He told me that my whole work was an attempt to make people long gone come back alive.". Well-read as a child, he absorbed the family encyclopedia, preferring history to fiction. Upon receiving an 8 mm film movie camera for his 17th birthday, he shot a documentary about an Ann Arbor factory. Turning down reduced tuition at the University of Michigan, he attended the new Hampshire College, an alternative school in Amherst, Massachusetts with narrative evaluations rather than letter grades and self-directed academic concentrations instead of traditional majors. He worked in a record store to pay his tuition.

Eugène Henri Paul Gauguin (French pronunciation: [øˈʒɛn ãˈʁi ˌpol ɡoˈɡɛ̃]; 7 June 1848 – 8 May 1903) was a leading French Post-Impressionist artist who was not well appreciated until after his death. Gauguin was later recognized for his experimental use of colors and synthetist style that was distinguishably different from Impressionism. His work was influential to the French avant-garde and many modern artists, such as Pablo Picasso, and Henri Matisse. Gauguin’s art became popular after his death and many of his paintings were in the possession of Russian collector, Sergei Shchukin. He was an important figure in the Symbolist movement as a painter, sculptor, print-maker, ceramist, and writer. His bold experimentation with coloring led directly to the Synthetist style of modern art while his expression of the inherent meaning of the subjects in his paintings, under the influence of the cloisonnist style, paved the way to Primitivism and the return to the pastoral. He was also an influential proponent of wood engraving and woodcuts as art forms.
