Herman Keiser, 1946
A year after being discharged from the Navy, Keiser, 31, was nearly broke when he arrived at Augusta. He took the lead on the 3rd hole of the first round and came to the 72nd hole leading Ben Hogan by a shot. Keiser three-putted for bogey, but Hogan missed a two-footer for par, and Keiser won for the first time on the PGA Tour.
Keiser won twice more in '46. The next year he played in the Ryder Cup and had another victory—the last of his career. Within a few years he was off the Tour.
Claude Harmon, 1948
The 31-year-old Harmon tied the tournament record with a nine-under 279 and set a Masters record with a five-shot margin over Cary Middlecoff.
The head pro at Winged Foot in suburban New York City, Harmon is the last club professional to win a major. He tied for third at the 1959 U.S. Open at Winged Foot and three times made the semifinals of the PGA Championship, which was then a match-play event.
