HERBERT McLEAN EVANS (1882 - 1971) became associate professor of anatomy at Johns Hopkins University, then moved to California in 1915 and was made professor of anatomy at the University of California, Berkeley, a position he held until his death. His medical research at Berkeley addressed problems relating to human nutrition, endocrinology, embryology, and histology. In 1922 along with Katharine Scott Bishop, during feeding experiments on rats, he co-discovered Vitamin E which is needed for human reproduction (papers offered here). Evans became director of the Institute of Experimental Biology at Berkeley in 1931. With Gladys Anderson Emerson, he reported the isolation of the pure Vitamin E from wheat germ in 1937.
