Muir, c.1902 John Muir (1838-1914) led the nation toward an understanding and appreciation of the natural environment and its value as both a material and spiritual resource. His most important national contribution grew out of his political activism. Recognized as one of the driving forces behind the National Park system, Muir was instrumental in the establishment of Yosemite, Sequoia, Grand Canyon, Mt. Rainier, and other parks. As founder and first president of the Sierra Club in 1892, he established the most influential organization in the conservation field.
Since 1970, Holt-Atherton Special Collections has been the repository for the John Muir Papers. Today, approximately 75% of the extant papers of Muir are housed at the Holt-Atherton Special Collections.
