Henry C. ShermanDied 7 Oct 1955 at age 79 (born 16 Oct 1875).Henry Clapp Sherman was an American biochemist who did pioneer work in developing assay methods and determining functions of vitamins. He established the average human requirements for calcium (1931), phosphorus, and iron, and for many years his studies were considered the best guides to the health requirements for these minerals. He also determined the human daily requirement of calcium (1931) and B vitamins (1932), and his major study on vitamin A defined a suitable weekly dose (1934), and its storage in the body (1940). In other nutrition studies, he also identified iron-deficiency anaemia, began investigating cobalt in 1946, and debunked the value of spinach. |
