Bernhard Eduard Fernow was the third chief of the USDA's Division of Forestry of the United States from 1886 to 1898, preceding Gifford Pinchot in that position, and laying much of the groundwork for the establishment of the United States Forest Service in 1905. Fernow's philosophy toward forest management may be traced to Heinrich Cotta's preface to Anweisung zum Waldbau or Linnaeus' ideas on the "economy of nature." Fernow has been called the "father of professional forestry in the United States."

Gifford Pinchot was an American forester and politician. He served as the fourth chief of the U.S. Division of Forestry, as the first head of the United States Forest Service, and as the 28th governor of Pennsylvania. He was a member of the Republican Party for most of his life, though he joined the Progressive Party for a brief period.
