Emerson was born in
Ithaca, New York. His father, Alfred Emerson, Sr. was an
archaeologist and professor at Cornell University, and his mother Alice Edwards Emerson a concert pianist. His grandfather was a Presbyterian pastor. Of his three older siblings, his sister
Edith Emerson became an artist and museum curator, and another sister
Gertrude Emerson Sen became the editor of
Asia magazine in India. He took an interest in music in early life and while at the Interlaken School in
Rolling Prairie, Indiana from 1910 to 1914 he started the school poultry farm. He then went to
Cornell University to study poultry science but majored in entomology where he was taught by the
Comstocks. One of his classmates was
Karl P. Schmidt, the herpetologist. It was Cornell that Emerson met Winifred Jelliffe, daughter of a well-known psychiatrist. They got engaged in 1918, just before Emerson was drafted for nine months in the army. On a suggestion from
William Beebe, he visited the research station of the New York Zoological Society at
Kartabo in British Guiana and began examining termites, an area that he studied throughout his life. He married and made more trips to Kartabo. In 1921, he joined the
University of Pittsburgh as an instructor. He obtained a PhD from Cornell in 1925 with a Guggenheim Fellowship. From 1929 to 1962 he was Professor of Zoology at the University of Chicago. In 1935 he visited the
Barro Colorado Island. From 1940 to 1976 was Research Associate of the
American Museum of Natural History. In 1941 he served as president of the
Ecological Society of America, and in 1958 as president of the
Society of Systematic Zoology. Emerson and Winifred had a daughter, Helena, who became a professor of sociology, and a son William Jelliffe who worked on anatomy at the University of California. Winifred died in 1949 after which he married Eleanor Fish, with whom he had written a children's book
Termite City (1937). Emerson's collection of termites was donated to the
American Museum of Natural History and contained about a million specimens of about 1745 species of termites. == Honors ==
