Born 5 Dec 1892; died 16 Oct 1955 at age 62.
American zoologist noted for his research on animal reproductive organs and internal secretions. Moore systematically studied the gonads and associated ducts and glands of vertebrates. Collaborating with T.F. Gallagher and F.C. Koch at the University of Chicago, he became the first to isolate testicular secretion containing the male sex hormones androsterone and testosterone; the former primarily influences the growth and development of the male reproductive system, whereas the latter is responsible for inducing and maintaining secondary male sex characteristics. This discovery (c. 1929) paved the way for research into the chemical makeup of such androgens and their production.
