Monique Wittig (1935–2003) was a French-born feminist theorist and the author of L’Opoponax and Les Guérillères. Her writing focused on the performativity of gender, sexuality, and lesbian feminism. She studied at the Sorbonne and The School for Advanced Studies in the Social Sciences (L’École des Hautes Études en Sciences Sociales), and later taught at such institutions as Vassar College and University of California–Berkeley.
