Monique Wittig (; July 13, 1935 – January 3, 2003) was a French author, philosopher and feminist theorist who wrote about abolition of the sex-class system and coined the phrase "heterosexual contract". Her seminal work is titled The Straight Mind and Other Essays. She published her first novel, L'Opoponax, in 1964. Her second novel, Les Guérillères (1969), was a landmark in lesbian feminism. Biography Monique Wittig was born in 1935 in Dannemarie, Haut-Rhin, France. In 1950 she moved to Paris to study at the Sorbonne. In 1964 she published her first novel, L'Opoponax which won her immediate attention in France. After the novel was translated into English, Wittig achieved international recognition. She was one of the founders of the Mouvement de libération des femmes (MLF) (Women's Liberation Movement). In 1969 she published what is arguably her most influential work, Les Guérillères, which is today considered a revolutionary and controversial source for feminist and lesbian thinkers around the world. Its publication is also considered to be the founding event of French feminism. Wittig earned her PhD from the School for Advanced Studies in the Social Sciences, after completing a thesis titled "Le Chantier littéraire". Wittig was a central figure in lesbian and feminist movements in France. In 1971, she was a founding member of the Gouines rouges ("Red Dykes"), the first lesbian group in Paris. She was also involved in the Féministes Révolutionnaires ("Revolutionary feminists"), a radical feminist group. She published various other works, some of which include the 1973 Le Corps lesbien (or The Lesbian Body) and the 1976 Brouillon pour un dictionnaire des amantes (or Lesbian Peoples: Material for a Dictionary), which her partner, Sande Zeig, coauthored. In 1976 Wittig and Zeig moved to the United States where Wittig focused on producing work of gender theory.

With various editorial positions both in France and in the United States, Wittig's works became internationally recognized and were commonly published in both French and English. She continued to work as a visiting professor in various universities across the nation, including the University of California, Berkeley, Vassar College and the University of Arizona in Tucson.
