142562 Graetz           Discovered 2002 Oct. 10 by M. Kretlow at Trebur.
The German Officer Paul Graetz (1875-1968) was the first person to cross southern Africa by automobile. He started at Dar es Salaam (Tanzania) on 1907 Aug. 10 and completed the challenging 5000-km journey at Swakopmund (Namibia) on 1909 May 1. During 1911-1912 he traveled across Africa by motor-boat.
