Hoosier paleontologists

Jesse James Galloway

Galloway was a Hoosier paleontologist educated at Indiana University and is noted for having received the first PhD in Geology awarded there in 1913. Galloway studied with E.R. Cumings, first on the Indiana Ordovician sections of the Cincinnati Arch, notably the section exposed in the railway cutting at Tanners Creek, and later on atrata from the rest of the state. Galloway was a pioneer in stratigraphic and industrial applications of micropaleontology and taught the first courses in micropaleontology and petroleum geology at IU.
