Abstract
This is a memorial article for Yvonne Choquet-Bruhat, who was one of the great pioneers of mathematical general relativity and of partial differential equations. Starting with her 1952 result on local existence of solutions of the vacuum Einstein field equations, she obtained many results on the Einstein evolution equations, the Einstein constraint equations, and the equations of supergravity. Her methods have also been important for numerical relativity. She also wrote several textbooks and a memoir. An abridged version of this article has been submitted to AMS Notices.
