Paul Dubreil, 1954

Paul Dubreil (born March 1, 1904 in Le Mans , † March 9, 1994 in Soisy-sur-École near Paris ) was a French number theorist.

Dubreil was the son of a mathematics high school teacher in Le Mans and studied from 1923 at the École normal supérieure (ENS) and the Sorbonne . After he was first nationwide in the competition for aggregation in 1926, he became a lecturer at the ENS and received his doctorate in 1930, but before and after that he stayed with Emil Artin at the University of Hamburg, usually with a Rockefeller scholarship . Here he also met Emmy Noether , whom he followed to Göttingen (where he worked with Noether's student Bartel Leendert van der Waerden ) and Frankfurt. He also studied in Rome with the leading Italian algebraic geometers Guido Castelnuovo , Federigo Enriques and Francesco Severi . Back in France he went to Lille University in 1931 and Nancy University in 1933 . In 1946 he went to the Sorbonne, where he became professor of number theory in 1954.

Dubreil dealt with algebra ( semigroups ), algebraic geometry and number theory. He had a seminar on algebra and number theory in Paris with Charles Pisot from the 1950s (originally founded by Albert Chatelet ) and was also a member of Nicolas Bourbaki for a short time in the 1940s .

Since 1930 he was married to the mathematician Marie-Louise Jacotin (1905-1972), with whom he also worked mathematically (she published under Jacotin-Dubreil). In 1958 he was President of the Société Mathématique de France .
