Jack Kramer

John Albert Kramer (August 1, 1921 - September 12, 2009) was an American tennis player of the 1940s and 1950s. A World No. 1 player for a number of years, and one of the greatest tennis player of all time. He was considered the father and the leading promoter of the professional tennis tours. He was a relentless advocate for the establishment of Open Tennis between amateur and professional players. Open Tennis lost by five votes in 1960, but became a reality in 1968. In 1970, he created the Mens Grand Prix points system. In 1972, he helped found the Association of Tennis Professionals (ATP) with Donald Dell and Cliff Drysdale, and was the first Executive Director. He was unpaid at his request. In that role, he was the leader of an ATP boycott of Wimbledon in 1973, for the banning of Nikola Pilić from the tournament. Tall and slim, he was the first world-class player to play "the Big Game", a consistent serve-and-volley game, in which he came to the net behind all of his serves, including the second serve.
