French mathematician, who worked on both partial differential equations and algebraic topology. Leray wrote an important paper that founded the study of weak solutions of the Navier–Stokes equations. Together with Juliusz Schauder, he discovered a topological invariant, now called the Leray–Schauder degree, which they applied to prove the existence of solutions for partial differential equations lacking uniqueness. His main work in topology was carried out while he was in a prisoner of war camp in Edelbach, Austria from 1940 to 1945. Lerays work of this period proved seminal to the development of spectral sequences and sheaves. These were subsequently developed by many others, each separately becoming an important tool in homological algebra. Jean Leray died on 10 November 1998, aged 92, in La Baule.

Jean Leray was a French mathematician who made significant contributions to the fields of partial differential equations, functional analysis, and topology. He is best known for his work on the Leray-Schauder theorem, which is a fundamental result in the theory of nonlinear partial differential equations.
Leray was born in Nantes, France, on November 7, 1906. He studied at the École Polytechnique and the École Normale Supérieure in Paris. After graduating, he taught at the universities of Strasbourg and Nancy. In 1945, he was appointed to the chair of mathematics at the Sorbonne, where he remained until his retirement in 1977.
Leray's research interests included partial differential equations, functional analysis, and topology. He made significant contributions to each of these fields. In partial differential equations, he developed the theory of weak solutions and the Leray-Schauder theorem. In functional analysis, he introduced the notion of a Banach space and studied the theory of operators on Banach spaces. In topology, he made important contributions to the theory of fibre bundles.
Leray was a member of the French Academy of Sciences and the American Academy of Arts and Sciences. He received the Grand Prix des Sciences Mathématiques from the French Academy of Sciences in 1954.
Leray died in Paris, France, on November 14, 1998.
