Eadweard Muybridge was an English photographer important for his pioneering work in photographic studies of motion, and early work in motion-picture projection. He adopted the first name Eadweard as the original Anglo-Saxon form of Edward, and the surname Muybridge believing it to be similarly archaic.
At age 20, he emigrated to America as a bookseller, first to New York, and then to San Francisco. Planning a return trip to Europe in 1860, he suffered serious head injuries in a stagecoach crash in Texas. He spent the next few years recuperating in England, where he took up professional photography, learning the wet-plate collodion process, and secured at least two British patents for his inventions. He went back to San Francisco in 1867, and in 1868 his large photographs of Yosemite Valley made him world-famous.
In 1874 Muybridge shot and killed Major Harry Larkyns, his wife's lover, but was acquitted in a jury trial on the grounds of justifiable homicide. He travelled for more than a year in Central America on a photographic expedition in 1875.
