A. S. Packard

Alpheus Spring Packard (1839–1905) was an American entomologist and zoologist. Born in Brunswick, Maine, he studied at Bowdoin College and under Louis Agassiz at Harvard, served as an army surgeon during the Civil War, and was one of the founders of the journal The American Naturalist. He worked on the United States Entomological Commission's study of the Rocky Mountain locust and from 1878 taught zoology and geology at Brown University. A leading neo-Lamarckian, he wrote a biography of Lamarck, as well as the Guide to the Study of Insects, A Text-book of Entomology and large monographs on moths.
