17486 Hodler           Discovered 1991 Sept. 10 by F. Borngen at Tautenburg.
Ferdinand Hodler (1853-1918) founded modern Swiss painting with his use of allegorical themes, historical events, sights of the Alps, lakes and portraits. His monumental 1907-1908 mural Marching out of the Jenense students in the war of liberation in 1813 adorns the aula of Jena University.
