William Herbert Sheldon, Jr. (November 19, 1898 – September 17, 1977) was an American psychologist and numismatist. He created the field of somatotype and constitutional psychology that tried to correlate body types with behavior, intelligence and social hierarchy illustrated by his Ivy League nude posture photos. However, his work is generally dismissed by modern researchers.
