Yvonne Choquet-Bruhat (French: [ivɔn ʃɔkɛ bʁy.a] ⓘ; 29 December 1923 – 11 February 2025) was a French mathematical physicist now best remembered for her investigation of the mathematics of general relativity. Her proof that the Einstein field equations can be expressed as a well-posed initial-value problem was listed by the journal Classical and Quantum Gravity as one of thirteen "milestone" results in general relativity in an issue published in the centennial anniversary of its birth in 2015. She also studied non-Abelian gauge theory, relativistic hydrodynamics, and supergravity.
Choquet-Bruhat was the first woman to be elected to the French Academy of Sciences and was a Grand Officer of the Legion of Honour.
