17917 Cartan           Discovered 1999 Apr. 15 by P. G. Comba at Prescott.
Élie Cartan (1869-1951), the son of a blacksmith, became a very influential French mathematician. His major contribution is the development of the theory of exterior differential forms, which he applied to the study of Lie groups, differential geometry and systems of differential equations.
