Jean Paul Sartre

The leading figure of 20th-century existentialism. His style is marked by a stark, "engaged" realism designed to provoke moral crisis, often placing characters in claustrophobic settings—most famously in the play No Exit—to illustrate the burdens of radical freedom and bad faith. While he was a global intellectual celebrity and was awarded the 1964 Nobel Prize in Literature (which he famously refused), he faced significant contemporary pushback from both the political right and traditionalists for his atheism and Marxist leanings. One half of one of the most iconic intellectual romantic partnerships in history with Simone de Beauvoir.
