Body type, or somatotype, refers to the idea that there are three generalized body compositions that people are predetermined to have. The concept was theorized by Dr. W. H. Sheldon back in the early 1940s, naming the three somatotypes endomorph, mesomorph, and ectomorph. It was originally believed that a person's somatotype was unchangeable, and that certain physiological and psychological characteristics were even determined by whichever one a person aligns to. According to Sheldon, endomorphs have bodies that are always rounded and soft, mesomorphs are always square and muscular, and ectomorphs are always thin and fine-boned. He theorized that these body types directly influenced a person's personality, and the names were chosen because he believed the predominate traits of each somatotype were set in stone, derived from pre-birth preferential development of either the endodermal, mesodermal, or ectodermal embryonic layers.
