A Yale graduate, he studied at Berlin, Heidelberg, and Breslau; and was professor of palaeontology at Yale from 1866 to his death. He was authority on the extinct vertebrates of the Rocky Mountains, having conducted many scientific expeditions thither, and discovered more than 1,000 new specimens, many of which he described in the American Journal of Science, and which he presented to Yale University. For twenty years he labored upon a series of government reports containing an illustrated account of his discoveries. Three of these-on the "Odontornithes", the "Dinocerata", and "Lauropoda"-have appeared. He was president of the American Association for the Advancement of Science, vertebrate palaeontologist of the U. S. Geological Survey, president of the National Academy of Sciences, and fellow of the Geological Society of London. His work has been recognized by honorary degrees from great universities, and in many other ways, bringing him international reputation.
