The Third International Congress of Eugenics, held at New York's American Museum of Natural History in August 1932, was the single largest gathering of eugenicists-academics, researchers, medical specialists, and politicians-ever to have convened. A total of sixty-nine papers were presented at the two day conference, covering topics as widespread as birth selection versus birth control; immigration control; eugenics and education; heredity and environment; the dysgenic effects of war; heredity and disease; and, remarkable for the time, an advanced study of the science of genetics and inheritance.
