This ""official"" (definitive) history of the Professional Golfers' Association follows the organization's phenomenal growth since its formation in 1916. As might be expected, the main functions of the PGA involve arranging and operating pro tournaments and Ryder Cup Matches. Graffis' meticulously detailed tome treats everything from caddie programs to equipment (the first golf bags appeared c. 1880, and tees after WW I). . . modern club design and ball development to the curriculum at the PGA Business School. Historians of the game will be interested to know that ""golf remained very much a status symbol of the quality folk during the Roaring Twenties."" Or that it was Bing Crosby who ""really established tournament golf"" with his celebrity pro-ams in the mid-thirties, long before Arnie Palmer and TV coverage. Occasional profiles of golfing greats Walter Hagen and Gene Sarazen don't alter the fact that this is anything but light reading. An exhaustively well-researched reference--it helps if you can place Willie Dunn.
