Bibi Gaston will speak at the Camden Public Library on Friday, February 15, at 3 p.m. about her latest book, “Gifford Pinchot and the First Foresters: The Untold Story of the Brave Men and Women Who Launched the American Conservation Movement.” Pinchot, Gaston’s great-granduncle, served as Chief Forester of the U.S. Forest Service from 1905 to 1909. In 2005, Gaston unearthed six old boxes in the Library of Congress’s Pinchot Collection in Washington, D.C. Inside were 5,000 pages of letters, labeled simply “The Old Timers,” written by the first class of American Forest Rangers to serve under President Theodore Roosevelt and the first chief of the U.S. Forest Service, Gifford Pinchot. The letters tell of extreme hardship, fearless struggle, confrontations with cattlemen, miners and loggers, and the challenges of turning confrontations into cooperation and gratitude.
