52057 Clarkhowell           Discovered 2002 Aug. 15 by M. Schwartz and P. Holvorcem at the Tenagra Observatory, Cottage Grove.
Francis Clark Howell (1925-2007), generally known as "F. Clark Howell", was an American anthropologist. He altered his discipline by adding a broad spectrum of modern sciences to the traditional "stones and bones" approach of the past and is considered the father of modern paleo-anthropology.
