About Emile Grandjean

Lived 1861 – 1942 (aged 80–81). Emile Grandjean was a forester.

Emile A. Grandjean (October 31, 1861 – August 8, 1942) was an American forester who was the first supervisor of Boise National Forest, serving from 1908 to 1922.

Early life Grandjean was born on October 31, 1861, in Copenhagen, Denmark. He was born into a family of relative influence, with his father being named a King's Counsellor. Both his father and grandfather worked in the Danish royal forests and Grandjean received training as a forester. In 1883 Grandjean immigrated to the United States and moved to Idaho to become a trapper.

Career Grandjean joined the United States Forest Service in 1905 and after two years serving in various forests around Idaho, he was appointed as supervisor of Sawtooth National Forest West. In 1912 Grandjean was given a sequoia seedling by John Muir which was planted in Boise and grew into the state's largest sequoia tree. In 1922 Grandjean was injured on the job. He was offered a position as supervisor of the Nevada National Forest but instead chose to retire, moving to Caldwell, Idaho. He was related to Harlan J. Bushfield, the 16th Governor of South Dakota. Grandjean died on August 8, 1942. A crag in the Sawtooth National Forest is named Grandjean Peak in his honor, as is an unincorporated community close by.
