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.Naming citation (MPC batch dated 2013-04-25), IAU / Minor Planet Center, via NASA/JPL
