Jean-Paul Charles Aymard Sartre was a French philosopher, political activist, and writer, considered a leading figure in 20th-century French philosophy and Marxism. Sartre was one of the key figures in the philosophy of existentialism and was a proponent of Libertarian Marxism. His work has influenced sociology, critical theory, post-colonial theory, and literary studies. 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". June 21, 1905 – April 15, 1980; died at 74. Alive at the same time as Barack Obama, Albert Einstein, Pablo Picasso, Franz Kafka, and Pope Francis. Wiki link
