Alain Badiou was born in Rabat, Morocco in 1937. He studied at the Ecole Normale Superieure in the 1950s and, from 1969 until 1999, taught at the University of Paris VIII (Vincennes-Saint Denis) before returning to ENS as the Chair of the philosophy department. Much of Badiou's life has been shaped by his dedication to the consequences of the May 1968 revolt in Paris. Long a leading member of Union des jeunesses communistes de France (marxistes-leninistes), he remains, with Sylvain Lazarus and Natacha Michel, at the centre of L'Organisation Politique, a post-party organization concerned with direct popular intervention in a wide range of issues, including immigration, labor, and housing. Alain Badiou is the author of several successful novels and plays, as well as more than a dozen philosophical works.Zachary Luke Fraser teaches in the Contemporary Studies and History of Science and Technology Programmes at the University of King's College in Halifax, Nova Scotia, where he lives with his wife, Shan Mackenzie-Fraser, and their four children, two dogs and two cats.
