Philosopher, novelist, feminist, and existentialist Simone de Beauvoir dies in Paris, France. Simone de Beauvoir was an integral figure in the French existentialist movement and her 1947 book The Ethics of Ambiguity is generally considered to be one of the most accessible introductions to existentialism ever written.
Although deeply religious as a child, a crisis of faith at the age of 14 led her to becoming an atheist, which she remained for the rest of her life.
Simone de Beauvoir studied philosophy, mathematics, and literature, and it was during her studies that she met Jean-Paul Sartre, with whom she had a lifelong intimate relationship. She became much more widely known outside philosophy circles with the publication of The Second Sex, a book about both existentialism and feminism at the same time.
Beauvoir argues that "woman" is something socially constructed and thus an identity which is imposed and acquired rather than some sort of innate nature. Feminism thus requires a moral revolution so that women learn that being female isn't a deviation from some sort of "norm".
