George Bird Grinnell (1849-1938) was a historian, naturalist, explorer, sportsman, and conservationist. He helped to establish Yellowstone Park and Glacier National Park, co-founded the first Audubon Society, and along with Teddy Roosevelt, co-founded the Boone and Crockett Club. Grinnell was a long-time editor of Forest and Stream magazine and wrote several landmark books on the Pawnee, Blackfoot and Cheyenne peoples, having lived with and befriended the last generation of people from the Buffalo Days. Grinnell’s career as a writer and recorder of Indian way of life would later be characterized by Stephen Ambrose (author of Band of Brothers) as “of incalculable benefit to every student of Western or Indian history.”

Grinnell’s work is the focus of the fully illustrated title The Cheyenne Indians, which features over 100 photos and illustrations.
