Simone de Beauvoir was born in Paris in 1908. In 1929 she became the youngest person ever to obtain the agregation in philosophy at the Sorbonne, placing second to Jean-Paul Sartre. She taught at the lycees at Marseille and Rouen from 1931-1937, and in Paris from 1938-1943. After the war, she emerged as one of the leaders of the existentialist movement, working with Sartre on Les Temps Mordernes. The author of several books including The Mandarins (1957) which was awarded the Prix Goncourt, de Beauvoir was one of the most influential thinkers of her generation. She died in 1986.
