1975 LB. Discovered 1975 June 9 by E. Roemer at Kitt Peak.

Named for Bart J. {1906–1983} and Priscilla F. Bok {1896–1975}. This is the first minor planet discovered with the 229-cm telescope of the Steward Observatory to be numbered. It is named for the Boks in recognition of their role in bringing the large reflector of the Steward Observatory into operation and for their support of the astrometric work on comets, minor planets, and satellites. This minor planet was at far southern declination at discovery (and observations at Wellington were important in obtaining a reliable orbit). This is also in fitting association with the Boks, who have devoted much effort to study of the structure of the southern Milky Way and to encouragement of astronomy in the southern hemisphere.

Name proposed by E. Roemer and A. C. Gilmore.
