19349 Denjoy           Discovered 1997 Feb. 13 by P. G. Comba at Prescott.
Arnaud Denjoy (1884-1974) was one of a group of French mathematicians (including Baire, Borel and Lebesgue) who in the early twentieth century initiated a new approach to the theory of functions of real variables, measure theory and integration.
