January 9, 1908 – Birthdate of Simone de Beauvoir, French philosopher and author.
Simone Lucie Ernestine Marie Bertrand de Beauvoir was a French writer, intellectual, existential philosopher, political activist, feminist and social theorist. Though she did not consider herself a philosopher, she had a significant influence on both feminist existentialism and feminist theory.
De Beauvoir wrote novels, essays, biographies, autobiography and monograph on philosophy, politics and social issues. She was known for her 1949 treatise The Second Sex, a detailed analysis of women’s oppression and a foundational tract of contemporary feminism; and for her novels, including She Came to Stay and The Mandarins. She was also known for her lifelong open relationship with French philosopher Jean-Paul Sartre. (from Wikipedia)
