Simone-Lucie-Ernestine-Marie Bertrand de Beauvoir, commonly known as Simone de Beauvoir, was born in Paris, France on January 9, 1908 (d. April 14, 1986). She “was a French writer, intellectual, existentialist philosopher, political activist, feminist, and social theorist. While she did not consider herself a philosopher, Beauvoir had a significant influence on both feminist existentialism and feminist theory. Beauvoir wrote novels, essays, biographies, an autobiography, monographs on philosophy, politics, and social issues. She is best known for her novels, including She Came to Stay and The Mandarins, as well as her 1949 treatise The Second Sex, a detailed analysis of women’s oppression and a foundational tract of contemporary feminism.” (Source: Wikipedia)
Simone de Beauvoir adopted a woman named Sylvie Le Bon-de Beauvoir several years before her death in 1986. She did this to grant her the moral rights to her literary works. Sylvie had idolized de Beauvoir and met her when she was in her 60’s. They had formed a friendship over the years despite their age difference.
