Galloping Horse by Eadweard Muybridge, 1878

Was this Stanford University's first research project? Was there a moment midstride when horses had all hooves off the ground? Leland Stanford, the railroad baron and future university founder, bet there was—or at least that’s the story. It was 1872 when Stanford hired noted landscape photographer Eadweard Muybridge to figure it out. It took years, but Muybridge delivered. He rigged a racetrack with a dozen strings that triggered 12 cameras. Muybridge not only proved Leland Stanford right but also set off the revolution in motion photography that would ultimately become today's movies. Biographer Rebecca Solnit summed up Muybridge's life: “He is the man who split the second, as dramatic and far-reaching an action as the splitting of the atom.”
