Henry Clinton Fall (25 December 1862, Farmington, New Hampshire – 14 November 1939, Tyngsboro, Massachusetts) was an American entomologist.
He taught from 1884 to 1889 mathematics and physics in Chicago secondary schools,[1] and then in 1889 for health reasons moved to Southern California.
A visit from George Henry Horn inspired Fall to begin scientific study of insects and to write an 1893 article on beetles.
His insect collection and papers were left to the Museum of Comparative Zoology of Harvard University.
He inspired many coleopterists, including Edwin Van Dyke and Frank Ellsworth Blaisdell.
