E. D. (Edward Drinker) Cope

Born in Philadelphia in 1840, Edward Drinker Cope became a scientific prodigy early, publishing while still young and building a reputation as a zoologist, anatomist, and paleontologist. His work ranged far beyond dinosaurs: he studied reptiles, amphibians, and fishes in depth, and he described hundreds of species during a career marked by speed, confidence, and enormous ambition.

Cope spent much of his life exploring the American West and studying the flood of fossils coming from it. He became one of the best-known scientists of his era through his intense rivalry with Othniel Charles Marsh, a contest later known as the Bone Wars. That competition helped drive major fossil discoveries, even as it also brought personal conflict and professional controversy.

Despite financial troubles late in life, Cope remained active in research almost to the end of his life in 1897. Today he is remembered as a brilliant, restless naturalist whose work left a lasting mark on vertebrate paleontology and on the history of American science.
