In 1872 an Englishman photographed a running horse in California and succeeded for the first time in capturing an image of high-speed motion - the crucial breakthrough that eventually made movies possible. From Muybridge’s invention came Hollywood and from his patron’s sponsorship of technological research came Silicon Valley - two industries that have most powerfully shaped the modern world. The story of Muybridge’s own life while he was making his motion studies is equally riveting. He became an internationally renowned inventor and photographer whose pictures have now become classics - and in a blaze of publicity, stood trial for the murder of his wife’s lover. Gripping and erudite, this is a fascinating biography of a true pioneer and the larger story of how time and space were revolutionized in the 19th century.
