Eadweard James Muybridge, born Edward James Muggeridge in Kingston-on-Thames, England, April 9, 1830, emigrated to the United States about 1852. By 1855 he owned a bookstore in San Francisco specializing in illustrated books. He spent his early years photographing life in California and eventually became a skilled photographer with the United States Coast and Geodetic Survey, engaged in photographic survey work on the Pacific Coast and Southeast Alaska. His photographs of Southeast communities and the Tlingit Indians are believed to be the first photographs made in Alaska. Muybridge was a pioneer of motion photography, receiving international recognition for his photographs of animal locomotion. The results of his experiments were published in book form in 1878, titled, "The Horse in Motion," and in 1887, an eleven volume work containing 100,000 photographs titled "Animal Locomotion." Muybridge married Flora Stone in 1872, in San Francisco and had one son, Florido H. Muybridge. He died in England, May 8, 1904, and was cremated.
