Jean-Paul Charles Aymard Sartre (/ˈsɑːrtrə/, US also /ˈsɑːrt/; French: [saʁtʁ]; 21 June 1905 – 15 April 1980) was one of the key figures in the philosophy of existentialism (and phenomenology), a French playwright, novelist, screenwriter, political activist, biographer, and literary critic, as well as a leading figure in 20th-century French philosophy and Marxism. His work has influenced sociology, critical theory, post-colonial theory, and literary studies, and continues to do so. He was awarded the 1964 Nobel Prize in Literature despite attempting to refuse it, saying that he always declined official honors and that "a writer should not allow himself to be turned into an institution."
