In what year was the United States Forest Service founded as noted in the nonfiction book, Young Men & Fire?

The United States Forest Service was founded in 1905 by President Theodore Roosevelt and Pennsylvania Governor Gifford Pinchot. Pinchot was a diehard outdoor enthusiast. Both men felt that there was a need for a government entity that would protect the forests of America and hopefully, prevent the forest fires that devastated much of the land, particularly in the West.
