### Instruction: Tell me about Roger Federer
### Input: Roger Federer (German: [ˈrɔdʒər ˈfeːdərər]; born 8 August 1981) is a Swiss former professional tennis player. He was ranked world No. 1 by the Association of Tennis Professionals (ATP) for 310 weeks, including a record 237 consecutive weeks, and finished as the year-end No. 1 five times. He won 103 singles titles on the ATP Tour, the second most of all time, including 20 major men's singles titles, a record eight men's singles Wimbledon titles, an Open Era joint-record five men's singles US Open titles, and a joint-record six year-end championships. In his home country, he is regarded as "the greatest and most successful" Swiss sportsperson in history.

A Wimbledon junior champion in 1998 and former ball boy, Federer won his first major singles title at Wimbledon in 2003 at age 21. Between 2003 and 2009, Federer played in 21 out of 28 major singles finals. He won three of the four majors and the ATP Finals in 2004, 2006, and 2007 as well as five consecutive titles at both Wimbledon and the US Open. He completed the career Grand Slam at the 2009 French Open after three consecutive runner-up finishes to Nadal, his main rival until 2010. At age 27, he surpassed Pete Sampras' record of 14 major men's singles titles at Wimbledon in 2009.

Federer and Stan Wawrinka led the Switzerland Davis Cup team to their first title in 2014, following their Olympic doubles gold victory at the 2008 Beijing Olympics. Federer also won a silver medal in singles at the 2012 London Olympics, finishing runner-up to Andy Murray. After a half-year hiatus in late 2016 to recover from knee surgery, Federer returned to tennis, winning three more majors over the next two years, including the 2017 Australian Open over Rafael Nadal and an eighth singles title at the 2017 Wimbledon Championships. At the 2018 Australian Open, Federer became the first man to win 20 major singles titles and shortly the oldest ATP world No. 1 at age 36. In September 2022, he retired from professional tennis following the Laver Cup.

A versatile all-court player, Federer's perceived effortlessness has made him highly popular among tennis fans. Originally lacking self-control as a junior, he transformed his on-court demeanor to become well-liked for his graciousness, winning the Stefan Edberg Sportsmanship Award 13 times. He has won the Laureus World Sportsman of the Year award a record five times. Outside of competing, he played an instrumental role in the creation of the Laver Cup team competition. He is also an active philanthropist. He established the Roger Federer Foundation, which targets impoverished children in southern Africa, and has raised funds in part through the Match for Africa exhibition series. He is routinely one of the top ten highest-paid athletes in any sport and ranked first among all athletes with $100 million in endorsement income in 2020.
