Jesse Douglas, Fields Medal, 1936

Jesse Douglas (3 July 1897 – 7 September 1965) was an American mathematician.

Life and career[edit] He was born in New York, the son of Sarah (née Kommel) and Louis Douglas. He attended City College of New York as an undergraduate, graduating with honors in Mathematics in 1916. He then moved to Columbia University as a graduate student, obtaining a PhD in mathematics in 1920.

Douglas was one of two winners of the first Fields Medals, awarded in 1936. He was honored for solving, in 1930, the problem of Plateau, which asks whether a minimal surface exists for a given boundary. The problem, open since 1760 when Lagrange raised it, is part of the calculus of variations and is also known as the soap bubble problem. Douglas also made significant contributions to the inverse problem of the calculus of variations. The American Mathematical Society awarded him the Bôcher Memorial Prize in 1943.

Douglas later became a full professor at the City College of New York (CCNY), where he taught until his death. At the time CCNY only offered undergraduate degrees and Professor Douglas taught the advanced calculus course. Sophomores (and freshmen with advanced placement) were privileged to get their introduction to real analysis from a Fields medalist.
