Gifford Pinchot (August 11, 1865 - October 4, 1946) was an American forester and politician. Pinchot served as the first Chief of the United States Forest Service from 1905 until his firing in 1910, and was the 28th Governor of Pennsylvania, serving from 1923 to 1927, and again from 1931 to 1935. He was a member of the Republican Party for most of his life, though he also joined the Progressive Party for a brief period. Pinchot is known for reforming the management and development of forests in the United States and for advocating the conservation of the nation's reserves by planned use and renewal.

Pinchot hand-picked William Greeley, the son of a Congregational minister, who finished at the top of that first Yale forestry graduating class of 1904, to be the Forest Service's Region 1 forester, with responsibility over 41 million acres (170,000 km2) in 22 National Forests in four western states (all of Montana, much of Idaho, Washington, and a corner of South Dakota).  One year after the 1910 forest fire inferno, Great Fire of 1910, the religious Greeley succeeded in receiving a promotion to a high administration job in Washington. In 1920, he became Chief of the Forest Service. The fire of 1910 convinced him that Satan was at work, the fire converted him into a fire extinguishing partisan who elevated firefighting to the raison d'etre -- the overriding mission -- of the Forest Service. Under Greeley, the Service became the fire engine company, protecting trees so the timber industry could cut them down later at government expense. Pinchot was appalled. The timber industry successfully oriented the Forestry Service toward policies favorable to large-scale harvesting via regulatory capture, and metaphorically, the timber industry was now the fox in the chicken coop. Pinchot and Roosevelt had envisioned, at the least, that public timber should be sold only to small, family-run logging outfits, not to big syndicates. Pinchot had always preached of a "working forest" for working people and small-scale logging at the edge, preservation at the core. In 1928 Bill Greeley left the Forest Service for a position in the timber industry, becoming an executive with the West Coast Lumberman's Association.  When Pinchot traveled west in 1937, to view those forests with Henry S. Graves, what they saw "tore his heart out." Greeley's legacy, combining modern chain saws and government-built forest roads, had allowed industrial-scale clear-cuts to become the norm in the western national forests of Montana and Oregon. Entire mountainsides, mountain after mountain, were treeless. "So this is what saving the trees was all about." "Absolute devastation", Pinchot wrote in his diary. "The Forest Service should absolutely declare against clear- cutting in Washington and Oregon as a defensive measure", Pinchot wrote.
