Scientist, Physician. He served as the University of Pennsylvania's Professor of Anatomy from 1839 to 1843. His works "Crania Americana" (1839) and "An Inquiry into the Distinctive Characteristics of the Aboriginal Race of America and Crania Aegyptiaca" (1844), espoused ideas of racial difference (since debunked) that suggested that intellectual capacity can be derived from the size of a brain, and that African-Americans, Asians, and Native Americans were a different (and inferior) "species" of Human Being than European Caucasians. Much of this research was used in the 19th century as "scientific justification" for slavery, although Dr. Morton himself did not originate his research for that purpose.
His sons was Civil War Union General James St. Clair Morton and Army surgeon Thomas George Morton.
