Eadweard Muybridge is best known for his photographic studies of motion of humans and animals, although he was also a pioneer in landscape photography. Muybridge worked for the landscape photographer Carleton E. Watkins in 1867 before setting out on his own in the Yosemite Valley and at other locations on the West Coast, producing approximately two thousand photographs between 1868 and 1873. After 1873, Muybridge turned his attention to other subjects, particularly his study of motion.
