Jean-Louis Koszul (French: [kɔsyl]; January 3, 1921 – January 12, 2018) was a French mathematician, best known for studying geometry and discovering the Koszul complex. He was a second generation member of Bourbaki.
Koszul was educated at the Lycée Fustel-de-Coulanges in Strasbourg before studying at the Faculty of Science University of Strasbourg and the Faculty of Science of the University of Paris. His Ph.D. thesis, titled Homologie et cohomologie des algèbres de Lie, was written in 1950 under the direction of Henri Cartan.
Koszul married Denise Reyss-Brion on July 17, 1948. They had three children: Michel, Bertrand, and Anne.
He died on January 12, 2018 at the age of 97, nine days after his 97th birthday.
