This is the only biography of Bernhard Eduard Fernow, one of the most prominent foresters in the United States from his arrival in 1876 until his death in 1923. The first professional forester in North America, Fernow, while serving as chief of the U.S. Division of Forestry from 1886 to 1898, laid the foundation for what would become the U.S. Forest Service. He was the founding dean of Cornell’s first forestry school and the University of Toronto’s forestry school. Fernow also established Forestry Quarterly, predecessor of the Journal of Forestry, and also served as president of the Society of American Foresters. Helping establish forest management and forestry education in the United States and Canada, Fernow stands as a pivotal figure in North America’s forest and conservation history.
