Legendary fight, this would start Joe’s record reign as heavyweight champion.
Joe Louis vs James J Braddock 22/06/1937 United States Comiskey Park, Chicago, Illinois, United States

This moderator had grandparents who remembered this match, and while neither had anything against Braddock (they loved underdog stories), the thought of a ‘Negro’ winning the heavyweight championship of the world in the 1930′s thrilled them to death. When you spoke of Joe Louis in our household, you said it almost in a whisper because that’s the type of reverence he had at the time.
