Charles R. Knight’s murals and other paintings are displayed extensively in museums and private collections, and his works have set a standard throughout the world in the painting of both modern and prehistoric animals.Early in life he attended the art school at the Metropolitan Museum, and later pursued his studies at the Art Students League. He has studied the anatomy and movements of living animals both in the zoos of this country and those of Europe. His versatility and unique genius are evident in the uniform excellence of his animal pictures, landscapes and portraits. Mr. Knight is the author of Before the Dawn of History, which is widely read by the public and used in educational institutions. Another book on prehistory for younger readers and also one on Comparative Psychology and Anatomy of Animals will shortly appear in print. —The Editor [1938]. Charles R. Knight (1874–1953) is famous for his ground-breaking depictions of dinosaurs and other prehistoric animals, and of wildlife in general. As this article shows, his patient observation of captive animals—even those confined to the primitive cages commonly found in zoos of the time—enabled him to learn a great deal about animal behavior in the wild. Millions of people are exposed annually to Knight’s works in major institutions around the world, including the American Museum of Natural History in New York City, the Field Museum in Chicago, and the Natural History Museum of Los Angeles County.
