The Bryan brothers are identical twin brothers Robert Charles "Bob" Bryan and Michael Carl "Mike" Bryan, American professional doubles tennis players, and are the most successful duo of all time. They were born on April 29, 1978, with Mike being the elder by two minutes. The Bryans have won multiple Olympic medals, including the gold in 2012 and have won more professional games, matches, tournaments and Grand Slams than any other men's pairing. They have held the World No. 1 doubles ranking jointly for 430 weeks (as of August 24, 2015), which is longer than anyone else in doubles history. They have also finished the ATP year-end number 1 doubles team a record 10 times. Between 2005 and 2006, they set an Open Era record by competing in seven consecutive men's doubles Grand Slam finals.
