John Muir (1838-1914) was America's most famous and influential naturalist and conservationist. He is one of California's most important historical personalities. He has been called "The Father of our National Parks," "Wilderness Prophet," and "Citizen of the Universe." He once described himself more humorously, and perhaps most accurately, as, a "poetico-trampo-geologist-botanist and ornithologist-naturalist etc. etc. !!!!" Legendary librarian and author Lawrence Clark Powell (1906-2001), (anticipating an event that was not to occur until 2006), said of him: "If I were to choose a single Californian to occupy the Hall of Fame, it would be this tenacious Scot who became a Californian during the final forty-six years of his life."
