6112 Ludolfschultz           Discovered 1981 Feb. 28 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
Ludolf Schultz (b. 1937), professor at the Johannes-Gutenberg-Universität in Mainz, has dedicated much of his career to the study of noble gases in meteorites. He also has passionately taught planetology and put considerable effort into introducing the enigmatic field of meteoritics to the public.
