Editor's Take:

Simone de Beauvoir changed how the world thinks about being a woman. Her famous line, 'One is not born, but rather becomes, a woman', argued that femininity is shaped by society rather than nature. The Second Sex, published in 1949, became a founding text of modern feminism, and it was so controversial that the Vatican placed it on its list of banned books. She was also a novelist, winning France's top literary award, the Prix Goncourt, for The Mandarins. Her honest memoirs about her own life and ageing were as groundbreaking as her philosophy.
