Roger Federer is a Swiss professional tennis player born on August 8, 1981, in Basel. Widely considered one of the greatest tennis players in history, he holds the record for the most Grand Slam singles titles won by a male player, with 20 victories. Federer is known for his versatile and elegant playing style, achieving success on all surfaces. He has won Wimbledon a record eight times and completed the Career Grand Slam by winning the French Open in 2009. Federer has demonstrated remarkable longevity in the sport, remaining competitive well into his 30s. Beyond tennis, he is recognized for his sportsmanship and philanthropic efforts, including the establishment of the Roger Federer Foundation, which supports education and children’s welfare projects in Africa.
