This new biography, the first in more than three decades, offers a fresh interpretation of the life and work of the famed conservationist and Progressive politician. In addition to considering Gifford Pinchot's role in the environmental movement, historian Char Miller sets forth an engaging description and analysis of the man-his character, passions, and personality-and the larger world through which he moved. The author brings together insights from cultural and social history and recently discovered primary sources to support a new interpretation of Gifford Pinchot, whose activism not only helped define environmental politics in early twentieth century America but remains strikingly relevant today.
