George Henry Horn

George Henry Horn (1840 to 1897) was an American entomologist who specialized in the study of beetles. Born in Philadelphia, he graduated in medicine from the University of Pennsylvania in 1861 and from 1862 to 1866 served as surgeon to the infantry of the California Volunteers, collecting insects extensively in California, Arizona and New Mexico. He then practised medicine in Philadelphia, specializing in obstetrics, and was president of the Entomological Society of Philadelphia, the predecessor of the American Entomological Society, until his death. Elected to the American Philosophical Society in 1869, he published more than 150 papers defining about 150 genera and more than 1550 species, worked closely with John Lawrence LeConte, and bequeathed his insect collections to the American Entomological Society, now held in the Museum of Comparative Zoology at Harvard University.
