Later, Marxist political thinker Louis Althusser was a student at ENS and taught there for many years, and many of his disciples later became known for their own thought: among them were Étienne Balibar, philosopher Alain Badiou, who still teaches at the school as an emeritus professor, and Jacques Rancière. Still later, in the 1940s and 1950s, the world-renowned thinker Michel Foucault, founder of the history of systems of thought and future professor at the Collège de France was a student a few years ahead of the founder of deconstruction, Jacques Derrida and the thinker of individuation Gilbert Simondon. The tradition continues today through such philosophers as Jacques Bouveresse, Jean-Luc Marion, Claudine Tiercelin, Francis Wolff and Quentin Meillassoux, and the school has also produced prominent public intellectuals like Stéphane Hessel and such New Philosophers as Bernard-Henri Lévy and Benny Lévy.
