<human>: William Tatem Tilden II (February 10, 1893 - June 5, 1953), nicknamed "Big Bill," was an American male tennis player. He is often considered one of the greatest tennis players of all time. Tilden was the World No. 1 player for six years from 1920 through 1925. He won 15 Major singles titles including ten Grand Slam events, one World Hard Court Championships and four Pro Slam tournaments.

On 31 December 1930, in need of money, he turned professional and joined the fledgling pro tour, which had begun only in 1927. For the next 15 years, he and a handful of other professionals such as Hans Nusslein and Karel Kozeluh barnstormed across the United States and Europe in a series of one-night stands, with Tilden still the player that people primarily paid to see. Even with greats such as Ellsworth Vines, Fred Perry, and Don Budge as his opponents, all of them current or recent world no. 1 players, it was often Tilden who ensured the box-office receipts--and who could still hold his own against the much younger players for a first set or even an occasional match.  Tilden thought he reached the apogee of his whole career in 1934 at 41 years old; nevertheless, that year he was dominated in the pro ranks by Ellsworth Vines. American Lawn Tennis reported that Vines had an edge of 11-9 in the first phase of their tour from January 10 through February 16 and that Vines led Tilden by 19 matches after the second phase of their tour, played from March 21 through May 17. Tilden had won 17 times for the entire year, per an Associated Press report, so a probable win-loss record at tour's end was 36-17 in Vines' favor. Both players then met at least 6 times during the rest of the year (Ray Bowers has listed 5 tournament matches and 1 one-night program), all lost by Tilden.  In 1945, the 52-year-old Tilden and his long-time doubles partner Vinnie Richards won the professional doubles championship--they had won the United States amateur title 27 years earlier in 1918.
