John Muir
His letters, essays, and books describing his adventures in nature, especially in the Sierra Nevada, have been read by millions. His activism has helped to preserve the Yosemite Valley, Sequoia National Park and many other wilderness areas. The Sierra Club, which he co-founded, is a prominent American conservation organization. In his later life, Muir devoted most of his time to the preservation of the Western forests. As part of the campaign to make Yosemite a national park, Muir published two landmark articles on wilderness preservation in The Century Magazine, "The Treasures of the Yosemite" and "Features of the Proposed Yosemite National Park"; this helped support the push for U.S. Congress to pass a bill in 1890 establishing Yosemite National Park. The spiritual quality and enthusiasm toward nature expressed in his writings has inspired readers, including presidents and congressmen, to take action to help preserve large nature areas.
