112328 Klinkerfues           Discovered 2002 June 16 by M. Meyer at Palomar.
Ernst Friedrich Wilhelm Klinkerfues (1827-1884), an astronomer at the Göttingen Observatory, started as an assistant to Gauss. Between 1853 and 1863 he discovered six comets, and he wrote the treatise Theoretische Astronomie (1871). Klinkerfues also worked in meteorology and invented several instruments.
