Event: Everything (no, seriously)
Hails From: Prague, Oklahoma
Medal Count: Two gold medals at the 1912 Olympic Games
Most Memorable Moment: Though his name may not be as familiar, he's considered by many to be one of the most versatile athletes of all time. On top of snagging Olympic gold for the pentathlon and decathalon, he also played professional baseball, basketball and football.
Betchya Didn't Know That: Rumor has it that at the closing ceremonies, Sweden's King Gustav told him, "You, sir, are the greatest athlete in the world." To which he responded, "Thanks, King."
