12145 Behaim           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Martin Behaim (1459-1507) was a German merchant, astronomer and cosmographer from Nürnberg. He traveled through Europe and became a Portuguese knight. He developed the earliest terrestrial globe, Erdapfel, or `Earth Apple', with a diameter of about 50 cm.
