15282 Franzmarc           Discovered 1991 Sept. 13 by F. Borngen and L. D. Schmadel at Tautenburg.
Expressionist painter and graphic artist Franz Marc (1880-1916) created an individual style, especially with animal representations. He invented geometrized and rhythmically arranged image composition. He co-founded the group "Der blaue Reiter" in Munich in 1911. The name was suggested by the first discoverer.
