@ The elder and favored of two girls, de Beauvoir was born into a bourgeois family. She pursued a glittering and precocious career as a philosopher at the Sorbonne, where she met Jean-Paul Sartre and at 21, she became the youngest quali- fied philosopher in France # De Beauvoir was devoted to Sartre for over 50 years. They saw each other every day, but never shared a house and had various other relationships though never lasting ones. Together, they formulated the philosophy of existentialism, and were also involved in the Resistance during the second world war # Rebellious but happy as a child, de Beauvoir always denied that her partnership with Sartre had anything in common with a bourgeois marriage. In The Second Sex (1949), which paved the way for the women's rights movement of the Sixties she wrote that the principle of marriage was obscene # After the war, de Beauvoir pro- duced a number of books, plays and theoretical essays. She became one of France's best- selling authors. Among her works was The Mandarins (1954), about Jean-Paul Sartre, herself and the writer Albert Camus. They spent many hours discus- sing literature and philosophy in cafes on Paris' Left Bank # Feminists admire de Beauvoir for her achievement as a thinker. Two of the main trends in twentieth century thought, feminism and existentialism, meet in her work. She united theory and activism, for example she wrote and campaigned for the right to contraception, and to legal abortion. She was very much ahead of her time @
