21110 Karlvalentin           Discovered 1992 Sept. 4 by F. Borngen and L. D. Schmadel at Tautenburg.
A Bavarian comedian, writer and film actor, Karl Valentin (Valentin Ludwig Fey, 1882-1948) had great success as a cabaret artist with his partner Liesl Karlstadt. He showed the universal powerlessness of the individual in comic sketches of abstract, absurd logic. The name was suggested by the first discoverer.
