Aldo Leopold was the originator of the concept of wilderness. He is
almost solely responsible for the creation of the Gila Wilderness
Area, fighting in Washington for its creation, and succeeding in
1924. It was the first such area in the world. At the time he was an
assistant district forester in the Albuquerque office. He has since
become better known for his book Sand Country Almanac,
condensing his lifetime of accumulated experience into an ecological
philosophy.
