Grinnell was born in Brooklyn in 1849 and grew up on the estate of ornithologist John James Audubon. Upon graduation from Yale, he dug for dinosaurs on the Great Plains with eminent paleontologist Othniel C. Marsh--an expedition that fanned his romantic notion of wilderness and taught him a graphic lesson in evolution and extinction. Soon he joined George A. Custer in the Black Hills, helped to map Yellowstone, and scaled the peaks and glaciers that, through his labors, would become Glacier National Park. Along the way, he became one of America's most respected ethnologists; seasons spent among the Plains Indians produced numerous articles and books, including his tour de force, The Cheyenne Indians: Their History and Ways of Life.
More than a chronicler of natural history and indigenous culture, Grinnell became their tenacious advocate. He turned the sportsmen's journal Forest and Stream into a bully pulpit for wildlife protection, forest reserves, and national parks. In 1886, his distress over the loss of bird species prompted him to found the first Audubon Society. Next, he and Theodore Roosevelt founded the Boone and Crockett Club to promote "fair chase" of big game. His influence among the rich and the patrician provided leverage for the first federal legislation to protect migratory birds--a precedent that ultimately paved the way for the Endangered Species Act. And in an era when too many white Americans regarded Native Americans as backwards, Grinnell's cries for reform carried from the reservation, through the halls of Congress, all the way to the White House.
Drawing on forty thousand pages of Grinnell's correspondence and dozens of his diaries, Taliaferro reveals a man whose deeds and high-mindedness earned him a lustrous peerage, from presidents to chiefs, Audubon to Aldo Leopold, John Muir to Gifford Pinchot, Edward S. Curtis to Edward H. Harriman. Throughout his long life, Grinnell was bound by family and sustained by intimate friendships, toggling between the East and the West. As Taliaferro's enthralling portrait demonstrates, it was this tension that wound Grinnell's nearly inexhaustible spring and honed his vision--a vision that still guides the imperiled future of our national treasures.
