The oldest known motion sequence photographed in real-time, was created in the US in 1878 by British photographer Eadweard Muybridge. Muybridge was hired by Leland Stanford to photograph Stanford's horses at full speed. Muybridge shot a very fuzzy unpublished picture in 1873 and a better one in 1877, but eventually made several sequential series in 1878 with a line of cameras along the race track. A press demonstration on June 15, 1878 at Stanford's stock farm in Palo Alto, California convinced everyone attending (especially when an accident caused by a broken strap was documented in the negatives). Several sequential series of running horses captured in June 1878 were soon published as "The Horse in Motion" and the achievement received worldwide praise (as well as astonishment about the actual positions of the legs of running horses that were much less graceful than imagined).
