William Tatem Tilden II (February 10, 1893 June 5, 1953), often called "Big Bill", was an American tennis player who was the World No. 1 player for 7 years, the last time when he was 38 years old.Unique among tennis players, Tilden became a great player only at the relatively advanced age of 27. Tall, lean, and gangly, with long arms, enormous hands, and exceptionally broad shoulders, Tilden possessed what was called at the time a "cannonball" service.Tilden may have spent more time analyzing the game of tennis than anyone before or perhaps since.In his 1979 autobiography, Jack Kramer, the long-time tennis promoter and great player himself, included Tilden in his list of the 6 greatest players of all time.
