The Chevalley Prize was established in 2014 by George Lusztig to honor Claude Chevalley (1909-1984). Chevalley was a founding member of the Bourbaki group. He made fundamental contributions to class field theory, algebraic geometry, and group theory. His three-volume treatise on Lie groups served as standard reference for many decades. His classification of semisimple groups over an arbitrary algebraically closed field provides a link between Lie''s theory of continuous groups and the theory of finite groups, to the enormous enrichment of both subjects.
