92892 Robertlawrence           Discovered 2000 Aug. 25 by M. W. Buie at Cerro Tololo.
Robert H. Lawrence Jr. (1935-1967) was selected for the Manned Orbiting Laboratory (MOL) program. He was the first African American to be selected as an astronaut and was the only MOL astronaut with a doctorate. He perished in a plane crash before he had the opportunity to go to space.
