Herman W. Keiser (October 7, 1914 – December 24, 2003) was an American professional golfer on the PGA Tour, best known for winning the Masters Tournament in 1946, his only major title.

[2] In 1942, Keiser interrupted his career to join the U.S. Navy for three years during World War II.

Despite the long layoff, he earned second-place finishes to Sam Snead at the Greater Greensboro Open, to Buck White at the Memphis Invitational, and twice to leading money winner Ben Hogan, at the Dallas Invitational and the Phoenix Open.

However, he achieved golfing immortality at the 1946 Masters Tournament when he took the lead on the third hole and never looked back, defeating Hogan by one stroke to earn $2,500 in first prize money.

[1] While the United States defeated Britain 11-1, Keiser's loss to Sam King (4 and 3) prevented the Americans from a clean sweep.
