60's trivia question?

Does anybody remember a guy in NYC called "Weird Harold"? He used to take photos of people. He would just approach people and take a photo shhot of them. Kind of a creepy guy but the amazing thing was, he would gain an incredible degree of trust from people that had just met him on the street. If you remember him you'll know who I'm talking about. I'm always trying to recollect 60's stuff and this just entered my head.
