On this date John Muir was born in Dunbar, Scotland. He immigrated with his family to Wisconsin in 1849 and spent his youth working on his father's farms in Marquette County, experiences that are recounted in The Story of My Boyhood and Youth (1913). In 1868 he moved to Yosemite Valley, California, where he became a conservationist and leader in the forest preserve movement. His work led to the creation of the first national parks, the saving of California's redwoods, and the founding of the Sierra Club.
