At the peak of the 1920s "land boom," Dunedin Isles Golf Club was built to attract new residents to the City of Dunedin. Scotsman Donald Ross, one of the world's foremost golf course architects, visited the site and designed the golf course which opened on January 1, 1927. During the Great Depression, the Club fell on hard times and in 1938, the course was deeded to the City with the stipulation that it be used for "recreational purposes." The City was able to renovate the course with proceeds from the sale of Dunedin Isles residential lots. On July 1, 1945, the Club officially became the PGA (Professional Golf Association) National Golf Club, first home course of PGA of America. The PGA held its Senior Tour Championship here from 1945-1962 during which time golfers competed for the historic Teacher's Trophy and the inaugural PGA Merchandise Show was held here in 1954. Many legendary PGA and LPGA professionals played here, including Tommy Armour, Patty Berg, Bobby Cruickshank, Jimmy Demaret, Walter Hagen, Ben Hogan, Byron Nelson, Gene Sarazen, Horton Smith, Sam Snead, Louise Suggs, Cyril Walker, Al Watrous and Babe Zaharias. Other players include golfing great Bobby Jones and baseball legend Babe Ruth.
