Hoosier paleontologists

August Frederic Foerste

Foerste was born in Dayton, Ohio where he spent most of his life as a high school teacher. He was educated at Denison University (BA, 1887) and Harvard (MA, 1888; PhD, 1890). Before returning to Ohio in 1893 he worked for the USGS studying stratigraphy in New England and studied briefly at Heidelberg University in Germany. Foerste participated in early geological surveys of Ohio, Indiana, Kentucky and Canada. He is known for his work on Ordovician fossils from the Cincinnati Arch, as well as other North American Paleozoic faunas.
