Theodore Hildreth Eaton Jr. (1907–1981) was an American scientist whose work ranged across zoology and vertebrate paleontology. Archival records from the University of Kansas say he earned his bachelor’s degree from Cornell in 1930 and a Ph.D. from the University of California, Berkeley, in 1933.
His research and writing focused on modern and fossil vertebrates, especially reptiles, fishes, and amphibians. He taught at several institutions over the course of his career, including Union College, American University, Southwestern College, East Carolina College, and the University of Kansas, where he was active for many years.
Alongside technical scientific papers, he wrote books for broader audiences, including Evolution. That mix of specialist research and readable science writing helps explain why his work still turns up in library catalogs, archives, and reprints today.
