"The best of the new generation of American historians" is how Stephen Ambrose described Douglas Brinkley, the author of this breakthrough biography of Theodore Roosevelt. TR's love of the outdoors is, of course, well known, but Brinkley proposes a thesis far more grand and significant. He argues that it was Roosevelt's ambitious Wild America program that turned conservationism into a universal endeavor. By tracing lines of influence on the future president's thought, he explains how the insights of people like Audubon, Darwin, John Burroughs, and John Muir shaped Roosevelt's Gospel of Preservation environmental actions. A superb choice for anyone who loves history and/or the environment.
