Muybridge’s stop-action experiments at Stanford’s Palo Alto Stock Farm earned him the title “father of cinema.” Yet he was also an extraordinary photographer. He arrived in San Francisco as Eadweard Muybridge, spelling his first name the way the Saxon kings had. When that didn’t get him enough attention, he dumped his name altogether and began signing his work as Helios, after the Greek god who drove a chariot across the sky. Another fun fact: Helios liked to put himself in his photos, sometimes without his clothes: like the ones of him swinging a pick… naked.
