Biography

Born in Riom-ès-Montagnes, Cantal, France. Brezis was the son of a Romanian immigrant father, who had come to France in the 1930s, and a Jewish mother who had fled from the Netherlands. His wife, Michal Govrin, a native Israeli, works as a novelist, poet, and theater director. Brezis received his Ph.D. from the University of Paris in 1972 under the supervision of Gustave Choquet. He was a professor at the Pierre and Marie Curie University and a visiting distinguished professor at Rutgers University. He was a member of the Academia Europaea (1988) and a foreign associate of the United States National Academy of Sciences (2003). In 2012 he became a fellow of the American Mathematical Society. He held honorary doctorates from several universities including National Technical University of Athens. Brezis is listed as an ISI highly cited researcher. He also served on the Mathematical Sciences jury for the Infosys Prize in 2013 and 2014. In 2024 he was awarded the Leroy P. Steele Prize for Lifetime Achievement of the AMS.

Brezis died in Jerusalem on 7 July 2024, at the age of 80.
