Lennox Lewis is a former three-time heavyweight champion of the world and boxing's last undisputed champion.
Lewis, who was a two-time lineal titlist as well, defeated everyone he faced in boxing, including three fights where he avenged his draw and two losses.
Born in London to Jamaican parents, Lennox Lewis spent his early part of life in England before immigrating to Canada to join his mother.
Talented in physical education at school, Lewis decided to take up his favourite sport - boxing - and was soon dominating the amateur ranks, beginning with a gold medal in the 1983 Junior World Championships.
Lewis reached the pinnacle at the 1988 Games, where he defeated Riddick Bowe in the final to win gold at super heavyweight.
Following his Olympic triumph, Lewis rejected an offer from Top Rank's Bob Arum to begin his professional career in England under promoter Kelly Maloney.
After the first phase of his career with Maloney, Lewis joined Main Events and won the British, Commonwealth and European titles with relative ease.
He then defeated Donovan 'Razor' Ruddock to become mandatory challenger for Bowe's WBC heavyweight title.
In a bizarre turn of events, Bowe threw his belt in the bin at a press conference and rejected a rematch from the 1988 Olympics in order to fight lesser opposition for more money.
The American was subsequently stripped of his status with the WBC awarding Lewis the title. Wins over Tony Tucker, Frank Bruno and Phil Jackson soon followed as champion.
Lewis would taste the first defeat of his career next, with Oliver McCall delivering a stunning upset in round two to dethrone the "Pugilistic Specialist" at Wembley.
Needing a change of direction, Lewis fired trainer Pepe Correa and hired Emanuel Steward - who had been in McCall's corner against Lewis.
It would become a hugely successful partnership which saw Lewis avenge his defeat three years later and become a two-time world champion.
After defeating Shannon 'Cannon' Briggs to add the lineal title to his WBC green-and-gold strap, Lewis had two fights with Evander Holyfield in 1999.
The first bout ended in a controversial draw while the rematch saw Lewis win via unanimous decision to add the WBA and IBF world titles to become Britain's first undisputed champion since Bob Fitzsimmons in 1899.
In doing so, Lewis was voted by the public as BBC Sports Personality of the Year in 1999.
A fighter with a point to prove, Lewis avenged another defeat in 2001 - this time to Hasim Rahman, who had delivered one of the biggest heavyweight upsets in history seven months earlier in South Africa.
Lewis then defeated Mike Tyson in a lucrative Las Vegas clash before calling it a day after overcoming Vitali Klitschko in an exhausting fight in 2003.
The greatest hits: Tyson, Klitschko and Rahman
Lewis had an incredible career and fought every name you can imagine, except for Bowe who declined the chance to fight him on the pro scene.
In 1999, Lewis - the WBC and lineal champion - collided with WBA and IBF titlist Holyfield in a unification clash to determine heavyweight's first undisputed champion since Bowe in 1992.
Despite many expecting Lewis to get his hand raised, it ended a split-draw. In the aftermath of the result, the sanctioning bodies ordered a rematch between the pair.
This time around, the bout was far more enthralling with both men going toe-to-toe and exchanging heavy shots.
It went the full distance at the Thomas and Mack Center with the scorecards 115-113, 116-112 and 117-111 in favour of Lewis.
What was to happen next will go down as one of the biggest upsets in history. After a closely fought four rounds, Lewis got stopped by 20-1 underdog Rahman in South Africa.
The American became an overnight sensation and soon signed for Don King. Every American network was desperate for his signature ahead of a first defence with the titles.
Showtime wanted him to take on Tyson, but Rahman rejected the offer and instead decided to fight Brian Nielson.
The proposed fight would collapse as Lewis had triggered his rematch clause from the original contract and took Rahman to court with the judge siding with Lewis.
Redemption followed as Lewis regained his heavyweight titles from Rahman to become a three-time champion.
Tyson was the next man to await Lewis. A press conference brawl between the fighters and their respective entourages helped promote the fight.
Lewis knocked Tyson down multiple times and eventually stopped Tyson inside eight rounds to retain his WBC, IBF, IBO, Ring and lineal titles.
The showdown generated 1.95 million buys on Showtime and HBO, which has not been bettered in a heavyweight fight since. Lewis was then stripped of his IBF title for refusing to fight his mandatory challenger, opting to face Kirk Johnson instead.
However, Johnson pulled out due to injury so up stepped Klitschko - his WBC mandatory. The fight itself was chaotic from the opening bell to the end of the sixth, with both men going toe-to-toe.
Despite a blistering start from Klitschko, the Ukrainian suffered a terrible cut above the left eye and at the end of the sixth, the referee halted proceedings. Due to Lewis' punches landing rather than a clash of heads causing the cut he was deemed the winner via TKO.
Lennox Lewis' net worth
Lewis made millions in a boxing career which lasted 14 years. His biggest purse came against Tyson with the fight generating an estimated $112million with nearly two million buys. Lewis and 'Iron' Mike received a guarantee of $17.5million each.
"The Lion" has pulled in close to six million PPV buys on Showtime and HBO which has contributed to his reported net worth of $140million. Not only was he one of the most lucrative prize fighters in heavyweight history, he also made shrewd investments outside of the ring.
In recent years, he has worked with Mimi's Rock to help develop nutritional supplements for athletes and is a chairman at Sun Seven Stars and Fight Blockchain Group.
On the TV front, Lewis made his acting debut on the third instalment of the Oceans franchise, Oceans 11, and was seen boxing with Wladimir Klitschko. Lewis also competed on NBC's Celebrity Apprentice and got fired in week 12 by President Donald Trump in 2008.
Lewis currently works as an analyst for FOX alongside Kate Abdo for boxing's biggest Premier Boxing Championship events.
Lewis holds dual British and Canadian citizenship after immigrating to Kitchener, Ontario, with his mother, Violet Blake. Lewis joined his mother in Canada after failing to behave himself in her absence at school in London.
His spouse is Violet Chan, a runner-up of Miss Jamaica in 2002, and they live together in Miami whilst also spending time at their apartment in Montego Bay.
The pair dated for five years before tying the knot in 2005 and have four children together; Leviah, Leya, Ling and Landon.
Lennox and his spouse founded non-profit organisation League of Champions Foundation to help inspire and create opportunities for underprivileged communities in Jamaica, Canada, UK and USA.
Their initiative includes physical health programmes and helps people develop educational requirements.
Amateur career: 1988 Olympics career
Lewis was a standout amateur and started to impress by winning the Junior World Championships in 1983. The following year, he represented Canada in the 1984 Olympic Games in Los Angeles and progressed into the quarter-finals before being eliminated by eventual winner Tyrell Biggs.
Despite having the option to turn professional and make more money, Lewis opted to remain as an amateur for the next Olympic Games.
In preparation, Lewis tasted defeat in the first-round of the 1986 World Championships before winning gold at the Commonwealth Games in the same year.
He continued his momentum by winning gold medals at the Pac American Games and North American Championships in 1987.
Lewis achieved his dream of becoming Olympic champion in 1988 as he stopped Bowe in the second round. His triumph in Seoul, Korea, saw Lewis become the first Canadian representative to win boxing gold in over 50 years.
It would go on to be his final fight in the amateurs leaving him with a 75-5 record in the ranks.
