"I was always interested in celebrity," says Ron Galella, the paparazzo who was responsible for some of the most memorable photographs in the 1960s, '70s, and '80s. "I think we all are. We admire them. We want to be rich or famous like them, in a way. And most of all, we're curious to see how are they in real life." More than anyone else, he managed to document the breadth of the glamorous, banal, and sometimes just plain weird world that reigned in New York at that time.

There he is wearing a football helmet behind Marlon Brando, who had broken Galella's jaw with a vicious punch. Jackie Kennedy, his favorite target, took out a restraining order against him. But Andy Warhol, another artist fascinated by fame, loved him, calling Galella his favorite photographer. "I like to capture famous people as they are—not what we see, the superstars on the screen in makeup and lighting. They're really not playing themselves. I want to capture the real themselves."

In anticipation of the release of his latest book, Ron Galella New York, we asked him to tell us the stories behind some of his most famous New York City moments.
