L. C. Dunn (1893-1974)
Faculty 1928-62

L. C. Dunn was one of the most significant figures in the emerging field of developmental genetics in the twentieth century. His T-locus work with the mouse established a number of important genetic principles, including ideas of gene interaction, the distribution of alleles in wild populations, and the factors that influence fertility. He wrote an important textbook of genetics, Principles of Genetics (1925), in collaboration with Sinnott (and later Dobzhansky); other significant books authored or coauthored by him include Heredity, Race and Society (1946), and A Short History of Genetics (1965). He worked in poultry genetics for eight years at the Agricultural Experiment Station in Storrs, Conn., from 1920–28. The remainder of his career was spent at Columbia University, where he worked with rats, mice, and fruit flies, and proved himself to be an inspiring teacher as well. His interest in international scientific collaboration led him to establish ties to Soviet scientists and to help relocate refugee scientists during World War II. He remained active in his profession to the end of his life. (Source:
