Peabody Museum of Natural History is established by the philanthropist George Peabody, uncle of Othniel C. Marsh (B.A. 1860), the nation’s first professor of paleontology. Yale’s earliest museum collection was begun in the eighteenth century and consisted of “natural and artificial curiosities” from around the world. The collection now includes more than eleven million specimens and is one of the largest natural history museums in the United States. The Great Hall features dinosaur skeletons, including the massive Apatosaurus, as well as Rudolph Zallinger’s (B.F.A. 1942, m.F.A. 1971) Pulitzer award-winning mural, The Age of Reptiles.
