Martina Navratilova

Navratilova won a record six consecutive singles majors across 1983 and 1984 while simultaneously winning the Grand Slam in doubles. Navratilova claims the best professional season winning percentage, 98.9% in 1983 (going 86–1 for the season), and the longest all-surface winning streak of 74 straight match wins. She reached the Wimbledon singles final 12 times, including for nine consecutive years from 1982 through 1990. Navratilova is one of the three tennis players, along with Margaret Court and Doris Hart, to have accomplished a career Grand Slam in singles, doubles, and mixed doubles, called the career "Boxed Set". She won her last major title, the mixed doubles crown at the 2006 US Open, shortly before her 50th birthday, and 32 years after her first major title in 1974.
Originally from Czechoslovakia, Navratilova was stripped of her citizenship when, in 1975 at age 18, she asked the United States for political asylum and was granted temporary residence. She became a US citizen in 1981. On January 9, 2008, Navratilova reacquired Czech citizenship, thus becoming a dual citizen. She stated she has not renounced her U.S. citizenship nor does she plan to do so, and that reclaiming Czech nationality was not politically motivated. Navratilova has been openly gay since 1981, and has been an activist on gay rights. Provided by Wikipedia
