Muir, John, 1838–1914, American naturalist, b. Dunbar, Scotland, studied at the Univ. of Wisconsin. He came to the United States in 1849 and settled in California in 1868. In recognition of his efforts as a conservationist and crusader for national parks and reservations, Muir Woods National Monument was named for him. He made extended trips throughout the country, often on foot; he also traveled in Alaska (discovering Muir glacier) and in Russia, India, and Australia. His books include The Mountains of California (1894), The Story of My Boyhood and Youth (1913), Steep Trails (1918). John of the Mountains (1938; ed. by L. M. Wolfe) contains his journals.
