Federer was born on 8 August 1981 in Binningen, near Basel and he grew up in Munchenstein, a suburb near Basel. He can speak Swiss German, German, French and English fluently.
The 2003 season was undoubtedly Federer's breakthrough year when he won his first Wimbledon title against Mark Philippoussis. Federer went on to reach nine ATP Tour finals, winning seven of them, and he completed the season with victory over Andre Agassi in the ATP Tour World finals.
In 2004, Federer won three of four Grand Slams for the first time in his career beginning with the Australian Open after defeating Marat Safin in the final. He then won his second successive Wimbledon crown when he beat Andy Roddick, before claiming the US Open with victory over Lleyton Hewitt.
Despite failing to win the first two slams of 2005, Federer's dominance on the grass continued with his third Wimbledon title in a row with another win over Roddick, while he continued his success at the US Open with victory over Agassi.
Federer won three Grand Slams in a season for the second time in his career in 2006, failing only in the French Open final to Rafael Nadal. Federer then reached all four Grand Slam finals once again in 2007, winning the Australian Open, Wimbledon, and the US Open, but again coming up short against Nadal in the French Open final.
In 2008, Federer won one Grand Slam title; the US Open after beating Andy Murray, but he was defeated by Nadal at the French Open and Wimbledon. He also won Olympic gold with doubles partner Stanislas Warwrinka in Beijing.
Federer completed his career Grand Slam in 2009 after finally landing the French Open title with victory over Robin Soderling. He also won Wimbledon, but was defeated by Nadal at the Australian Open and by Juan Martin del Potro at the US Open.
The 2010 season started well for Federer, who began the year by winning the Australian Open for a fourth time, however that success in Melbourne is the last Grand Slam trophy Federer has won, although he has won the ATP Tour World finals in 2010 and 2011.
Federer is one of the highest-earning athletes in the world and has accumulated in excess of $70 million in career prize money. He also has a lucrative contract with Nike footwear and apparel as well as other endorsements including Gillette, Mercedes-Benz, Rolex, and Swiss chocolate makers Lindt.
