Bob Marshall
Bob Marshall was born in New York, N.Y. on January 2, 1901 and died of heart failure on a train in November, 1939.
He was an early forester with a PhD in Forestry from The Johns Hopkins University and co-founder of The Wilderness Society. He was known as a tireless conservationist and visionary for wilderness preservation. His explorations and early field work in the Brooks Range of northern Alaska in the 1930's resulted in the posthumous publication of Alaska Wilderness, Exploring the Central Brooks Range in 1956 which served as a seminal work inspiring the establishment of the largest national park in the United States in the late 1970's - the Gates of the Arctic National Park.
The Bob Marshall Wilderness, in both Flathead and Lewis and Clark National Forests in Montana is named after him.
