Bobby Jones was ridiculously amazing. Obviously, he was a phenomenal golfer, in 1930 winning the original Grand Slam of championships (US Open, British Open, US Amateur, and British Amateur) at the age of 28. After retiring, he co-founded Augusta National, The Masters, and earned degrees from Georgia Tech (Mechanical Engineering) and Harvard (English).
Did I mention he was also an infantry captain on the shores of Normandy in WWII?
