Barnum is notable for two significant milestones in golf. He was the second golfer (after Jim Barnes), and one of only seven, 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.[1] His best finish in a major was T-16 at the 1958 PGA Championship.[2]
Barnum won five Michigan PGA Senior titles, and was runner-up three times in the PGA Seniors' Championship (1963, 1964, 1966).[3] He was inducted into the Grand Rapids Sports Hall of Fame in 1972,[4] and elected to the Michigan Golf Hall of Fame in 1984.[3]
