About the author
Oliver Perry Hay was an American herpetologist, ichthyologist, and paleontologist, born in Jefferson County, Indiana, on May 22, 1846, and died in Washington, D.C., on November 2, 1930. He studied at Eureka College in Illinois, graduating in 1870, and later taught science there before moving into museum and research work.
Over the course of his career, he worked at institutions including the Field Museum of Natural History and later the Carnegie Institution of Washington. He became especially known for compiling major catalogs of North American fossil vertebrates, work that helped organize scattered discoveries into standard references for other researchers.
Hay also wrote on living reptiles and fishes, so his scientific life was not limited to fossils alone. That mix of careful cataloging and broad natural-history interests makes him an appealing figure for readers interested in how American paleontology took shape in the late nineteenth and early twentieth centuries.
