11001 Andrewulff           Discovered 1979 June 16 by H.-E. Schuster at the European Southern Observatory.
German amateur astronomer Andre Wulff (b. 1958) has been involved for many years with observing comets and minor planets. He also serves on the board of directors of the Gesellschaft für Volkstümliche Astronomie, being coeditor of its quarterly journal Der Sternkieker and responsible for running the society's observatory.
