By setting aside more than 230 million acres of wild America for posterity between 1901 and 1909, Theodore Roosevelt made conservation a universal endeavor.

Tracing the role that nature played in Roosevelt's storied career, Brinkley brilliantly analyzes the influence that the works of John James Audubon and Charles Darwin had on the young man who would become our 26th president. With descriptive flair, the author illuminates Roosevelt's bird watching in the Adirondacks, wildlife obsession in Yellowstone, hikes in the Blue Ridge Mountains, ranching in the Dakota Territory, hunting in the Big Horn Mountains, and outdoor romps through Idaho and Wyoming. He also profiles Roosevelt's incredible circle of naturalist friends, including the Catskills poet John Burroughs, Boone and Crockett Club cofounder George Bird Grinnell, forestry zealot Gifford Pinchot, buffalo breeder William Hornaday, Sierra Club founder John Muir, U.S. Biological Survey wizard C.
