Darboux, Jean Gaston
Born: August 14, 1842, Nimes
[Died] February 23, 1917. French mathematician in Paris. After graduating from the Ecole Normale Supérieure (Ecole Normale Supérieure), he was assistant in mathematical physics under J. Bertrand at the Collège de France (1866-67), teacher at the École Normale Supérieure (1867-72), lecturer at the École Normale Supérieure (1872-73), professor of mechanics at the University of Paris (1873-80), professor of geometry (1880-89), and dean of the Faculty of Science (1889-90). He was not only an excellent teacher and a famous mathematician, but also a talented organizer. Most of his mathematical achievements were related to geometry. Others included second-order partial differential equations, approximation of functions, and Darboux's theorem. Lectures on the general theory of surfaces and on geometric applications of infinitesimal analysis (4 volumes, 87-96) is one of Darboux's most important works, and for a long time it was read as a standard text on differential geometry.
