15955 Johannesgmunden           Discovered 1998 Jan. 26 by E. Meyer at the Davidschlag Observartory, Linz.
Johannes von Gmunden (1380/1384-1442), a priest, humanist, mathematician and astronomer at the University of Vienna, brought the mathematical and astronomical knowledge of Arabia to Europe. Known for his precise ephemerides, he also published the first printed calendar in German.
