William Earl Mehlhorn (December 2, 1898 – April 5, 1989) was an American professional golfer who played on the PGA Tour in its early days, and was at his best in the 1920s.
Mehlhorn was born in Elgin, Illinois and lived a majority of his life in Seaford, New York when not traveling. He often wore cowboy hats on the course and was nicknamed "Wild Bill." He won 20 times on the PGA Tour, but did not win a major championship. Only a handful of golfers have won more often on the PGA Tour without claiming a major. He finished 14 times in the top-10 at majors. His best finish was runner-up to Walter Hagen at the PGA Championship in 1925. Mehlhorn competed on the first Ryder Cup team in 1927 as well as the inaugural Masters Tournament in 1934. He was a gallery favorite because of his uncanny accuracy from tee to green, but his game was undermined by problems with putting: the yips.
Mehlhorn also designed and plotted several golf courses across the country, including Pensacola, Florida's Osceola Golf Course.
Mehlhorn retired and moved to Miami, Florida with his family, where he coached golf at Florida International University with Bobby Shave during his later years. Mehlhorn and Shave wrote the book, Golf Secrets Exposed, in the early 1980s to summarize Mehlhorn's golf secrets and insight. Two versions of the book have been published since Mehlhorn's death.
