Eadweard J Muybridge celebrated in a Google doodle | Technology | guardian.co.uk: " Muybridge's "The Horse in Motion", a film strip-style collection of shots created using 24 cameras which capture the running habits of racehorses owned by Leland Stanford, a Californian businessman and animal breeder.
Stanford had wanted to know if galloping horses had all four legs off the ground, as previously portrayed by painters, and engaged Muybridge in an attempt to find out.
The photographs, taken in 1872 and regarded as one of the earliest forms of videography, demonstrated that all four legs often did leave the ground. However, they were not as artists had depicted them, with the legs stretched out fore and aft, but with the four legs tucked up under the horse."
