Originally established as the Division of Forestry in 1898, with Gifford Pinchot as its first lead forester. Although a division of the United States Department of Agriculture, the Division of Forestry did not have control over the national forest reserves.
Under Pinchot's leadership, he was able to promote scientific forestry and emphasize the controlled, profitable use of forests and other natural resources so they would be of maximum benefit to mankind. It was he who coined the term "conservation ethics."
After Theodore Roosevelt was elected president, Pinchot and Roosevelt persuaded the U. S. Congress to establish the United States Forest Service and charged it with overseeing the forest reserves of the U. S.
