(21110) Karlvalentin Main-belt Asteroid
Discovered on 4 September 1992 by Borngen, F., Schmadel, L. D. 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.Naming citation (20010705/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
