1994 Shane           Discovered 1961 Oct. 4 at the Goethe Link Observatory, Indiana University.
Named in honor of C. D. Shane, the second president of AURA (1958-1962). He played a major role in the planning and construction of the first telescopes and buildings on Kitt Peak and also the Tucson headquarters building. Even more important was his initiative in arranging for AURA to take on the responsibility for the construction of a major observatory in the southern hemisphere; this led to the establishment of the Cerro Tololo Interamerican Observatory. His long and distinguished career at the University of California spanned a period of more than 50 years; he was director of the Lick Observatory during 1945-1958 and was responsible for modernizing and expanding its facilities. Name proposed by F. K. Edmondson.
