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. == Early life and education == Yvonne Bruhat was born in Lille on 29 December 1923 in an intellectual family. Her mother was philosophy professor Berthe Hubert and her father was physicist Georges Bruhat, who died in 1945 in the Sachsenhausen concentration camp. He was sent there after refusing to divulge information on the French Resistance to Nazi occupation. Her brother François Bruhat also became a mathematician. Bruhat attended secondary school in Paris, earning her Baccalauréat in 1941, at the top of her class. She received the silver medal for physics in the prestigious Concours Général national competition.
