Which golfer won the US Open twice between the 1940s and 50s?

Question

He also earned a living a dentist before giving up to concentrate on the golf?

Answer 1

The man in question is Cary Middlecoff, who won the Open in 1949 and 1956 - he also won the Masters in 1955. At the time, his career as a dentist may well have proved more lucrative than a full time golfing career.
