As a longtime golf fan, I would say that the PGA Championship is the least prestigious of the four majors played annually in golf. But the tournament is still a major and every golfer would love to win the PGA Championship as many times as possible.
The PGA Championship is played annually in August, and is the last of the four majors to be played each year. I've listed all the golfers who have won the PGA Championship at least two times.
Of note, the PGA Championship was played as a match play event from its inception in 1916 until 1957. From 1958 on, the PGA Championship has been a played as a stroke play tournament. All players are from the United States unless otherwise noted.
Golfers who have won the PGA Championship the most times

T-1. Walter Hagen - 5
Walter Hagen is tied with Jack Nicklaus with five PGA Championships. All five of Walter Hagen's wins (1921, 1924-1927) came when the PGA Championship was a match play event. Walter Hagen won 11 majors in his career, and would have won more but he well over 40 years old when The Masters was first played in 1934.
