John O. Barnum (October 6 1911 – October 30 1996) was an American professional golfer who played on the PGA Tour in the 1950s and 1960s.Barnum is notable for two significant milestones in golf. He was the second golfer (and one of only six) ever to win a PGA Tour event after turning 50 and the only player to win his first PGA Tour event past the age of 50. The other significant milestone is that Barnum was the first player to win a PGA Tour event using a Ping putter.
