Muybridge was quite the character to say the least. Inventive, at times driven, ambitious, taking a knock on the head that probably drove him a little bit crazy - and he got away with murder - literally - after killing his wife's lover. And I think he's the only photographer to have an opera written about him? As well as being the influence for Duchamp's Nude Descending a Staircase No.2.
Starting off in England as the rather more mundane Edward James Muggeridge; Muybridge pretty much re-invented himself after making his way west. And while he is probably best known for his stop motion pictures of, first, horses and then people, he did much else besides. He set up shop with a studio in San Francisco selling his Mammoth plate photographs of Yosemite. Took some intriguing panoramic photographs of the growth of San Francisico, taken one plate at a time (in a way foreshadowing his motion studies) - of which Mark Klett has produced one of his re-photographic topographics thingy's. Muybridge also documented the little remembered but grinding and bloody Madoc Indian Wars in Orgeon and photographed in Central America after his acquittal for murder.
