The Milwaukee Open Invitational was a professional golf tournament in Wisconsin on the PGA Tour. It was played seven times from 1955 through 1961 at different courses in the Milwaukee area. During its final year, Arnold Palmer skipped the tournament to prepare for the British Open, which he won. The field at North Hills Country Club in Menomonee Falls did include 21-year-old Jack Nicklaus of Ohio State, already a veteran of eight majors and the reigning NCAA champion, he won his second U.S. Amateur a month later. The purse was $30,000 and Bruce Crampton won by a stroke; his winner's share was $4,300. Nicklaus was three strokes back at 275 (−5), tied for sixth. Two won the event twice, both at different courses: Cary Middlecoff (1955, 1958) and Ken Venturi (1957, 1960). Miller Brewing Company was the title sponsor for the first five editions; the tournament was initiated in 1955 with a five-year agreement, part of the company's centennial celebration.
