1869: Naturalist John Muir set pen to paper to capture his experience of awakening in the Sierra Nevada Mountains of California. Published in 1911, My First Summer in the Sierra is based on Muir's original journals and sketches of his 1869 stay in the vicinity of the Yosemite Valley. His journal tracks his three-and-a-half-month visit to the Yosemite region and his ascent of Mt. Hoffman and other Sierra peaks. Along the way, he describes the flora and fauna as well as the geography and geology of the area. Muir immigrated from Scotland to Wisconsin as a child. He attended the University of Wisconsin and began working as a mechanical inventor. After an 1867 industrial accident nearly blinded him, he abandoned his career as an inventor to work as a naturalist. (Source: Library of Congress)
