12612 Daumier           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Honoré Daumier (1808-1879) was a great French painter and lithographer. Among his many satirical and socially critical works is Parisians Waiting for the Famous Comet, 1857, a comet that had been predicted to strike the earth but that never materialized.
