Update to the Update: I've got to agree with the anonymous commentator below, the more I research it the more circumstantial evidence I find that it was Ray Middleton in the Superman suit. I'm leaving the updates though, controversy is fun.
UPDATE: Fellow Superman fan Nostalgia King has let me know that despite being credited to Ray Middleton, the actual guy in the Superman suit's name is unknown. Middleton was actually one of the judges of the Superboy and Supergirl contest.
Thanks for the info Nostalgia King.
I ran into some great photo's of actor Ray Middleton the first man to ever play the role of Superman in public, during "Superman Day" at the New York World's Fair on Independence day 1940.

I don't have much information on Superman Day, other then the photo's but they are cool, and I bet a bunch of young fans went nuts when they saw Superman himself in person.
