Boris Franz Becker, born on 22 November 1967 in Leimen, West Germany, is a former world No. 1 tennis player whose explosive power and youthful audacity transformed the sport in the 1980s. Widely regarded as one of the greatest players in tennis history, Becker captured the imagination of the global sporting public at just 17 years old when he became the youngest-ever winner of the men's singles title at Wimbledon in 1985, a record he achieved at 17 years, 7 months and 15 days. That breakthrough, delivered with a thunderous serve and a fearless all-court game, earned him the nickname "Boom Boom" and established him as the pioneer of power tennis, a style that would come to define the modern era.

Over the course of his professional career, Becker amassed 49 career singles titles and 15 doubles titles, including six Grand Slam singles crowns: three Wimbledon Championships, two Australian Opens, and one US Open. His rivalry with fellow German Steffi Graf's compatriot Michael Stich and his epic battles with Ivan Lendl, John McEnroe, and Andre Agassi became the stuff of legend. In addition to his Grand Slam success, Becker won 13 Masters titles and four year-end championships, and he claimed an Olympic gold medal in men's doubles at the 1992 Barcelona Games alongside Michael Stich. He also led Germany to two Davis Cup titles in 1988 and 1989, finishing his Davis Cup career with a remarkable 38–3 record in singles and a win percentage of 92.70%. In 1989, he was voted Player of the Year by both the ATP and the ITF, and in his autobiography, Andre Agassi described Becker as the world's most popular tennis star of the late 1980s. In 2006, Tennis magazine ranked him No. 18 on its list of the 40 greatest players of all time.

After retiring from professional tennis in 1999, Becker transitioned into a multifaceted career as a commentator, coach, and media personality. He notably served as head coach to Novak Djokovic for three years, a collaboration widely credited with helping the Serbian star reclaim the world No. 1 ranking and add multiple Grand Slam titles to his collection. Becker also pursued ventures beyond tennis, including playing poker professionally and working for an online poker company, while his personal life frequently made headlines in tabloid media. His post-playing years, however, were marked by significant legal troubles. In October 2002, the Munich District Court sentenced him to a suspended two-year prison term for tax evasion. He declared bankruptcy in the UK in 2017, and in April 2022, a UK court sentenced him to two and a half years in prison for hiding assets and loans from creditors and the bankruptcy trustee. He was released early on 15 December 2022 after serving eight months and was subsequently deported to Germany by UK authorities. Despite these controversies, Becker's legacy as a transformative athlete and one of the most charismatic and influential figures in tennis history remains firmly intact.
