Andrews, Roy Chapman (1884–1960), a United States naturalist, explorer, and author. He was a leading authority on whales and proved that Central Asia was one of the chief centers of early mammal and reptile life. Andrews was born in Beloit, Wisconsin, and graduated from Beloit College in 1906. He went to New York City to work for the American Museum of Natural History, becoming assistant curator of the department of mammals in 1911. On his early expeditions for the museum, 1908–14, Andrews studied whales and other water mammals along the coasts of Alaska and Asia. He received his M.A. degree from Columbia University in 1913.

As leader of the museum's Asiatic expeditions, 1916–32, Andrews explored Central Asia and worked extensively in Mongolia. He discovered one of the world's richest fossil fields in the Gobi desert, containing the first known dinosaur eggs and the remains of the long-extinct Baluchitherium, the largest known land mammal. His expeditions also discovered previously unknown geological strata and mapped new areas of the Gobi. Andrews became director of the museum in 1935 and retired as an honorary director in 1942.

Among his numerous books are Whale Hunting with Gun and Camera (1916); On the Trail of Ancient Man (1926); The New Conquest of Central Asia (1932); This Amazing Planet (1940); Under a Lucky Star (autobiography, 1943); Meet Your Ancestors (1945); Heart of Asia (1951); Nature's Ways (1951); and Beyond Adventure (1954).
