Ron Galella, King of the Paparazzi

Iconic Image
But Galella's obsession paid off, at least photographically, with his most famous shot, Windblown Jackie. "I call it my Mona Lisa," he's said. This arresting photo was taken on Madison Avenue in New York City in 1971: Galella jumped into a taxi to follow Onassis, taking the shot when she looked around as the driver honked his horn. It's now an acknowledged masterpiece, proof positive that the line between art and obsessive stalking is as thin as the photographic paper it's printed on. "I don't think she knew it was me," ventured Galella. "That's why she smiled a little."
