León Rozitchner (1924-2011) was a major philosopher and militant intellectual in Argentina. After studying at the Sorbonne in Paris with Maurice Merleau-Ponty (PhD, 1960), he returned home only to confront the terror of military coups and dictatorships, which for several years forced him into exile in Venezuela. After the so-called transition to democracy, he taught for many years at the University of Buenos Aires.

Bruno Bosteels, PhD (1995), is Professor of Latin American Cultures and Comparative Literature at Columbia University and the author of several books on Latin American politics and culture as well as on European philosophy and political theory. He is one of the main translators of Alain Badiou's works in English.
