This is Rudolph Wonderone, and...wait, Rudolph Wonderone, I hear you ask?? Who in the world is Rudolph Wonderone? Well, you'd likely know him -- not only far better, but period -- by his nickname: Minnesota Fats. If you ever saw the movie The Hustler (or even just know about it...), he's the real-life pool player whose character Jackie Gleason plays is based on.
Oddly enough, Wonderone wasn't known as "Minnesota Fats" at the time of the movie. He was known either as "Chicago Fats" or "Illinois Fats" or even "New York Fats" (why New York hogged its way in there, I have no idea. I'd guess he moved there at some point and set it up as his base, but still...). But after the movie, he became so synonymous with the character that he just started being referred to as Minnesota Fats.
