Succes 2012: Wladimir Klitschko, the WBA (Super), IBF, WBO, IBO & Ring Magazine Heavyweight Champion. He is the longest reigning Heavyweight Champion in history for the IBF, WBO & IBO heavyweight titles

Wladimir Klitschko (born 25 March 1976) is a Ukrainian heavyweight boxer. Klitschko is the WBA (Super), IBF, WBO, IBO & Ring Magazine Heavyweight Champion. His older brother Vitali Klitschko is the current WBC Heavyweight Champion. Klitschko is the longest reigning Heavyweight Champion in history for the IBF, WBO & IBO heavyweight titles, both in measurements of defenses and time & the 7th longest reigning heavyweight champion of all time. As of 2011, Boxrec rates Klitschko as the number 2 pound-for-pound in the world. Ring Magazine currently rates Klitschko as the number six pound-for-pound boxer in the world.

Since 2005, Klitschko has been the dominant force in the heavyweight division, defeating a majority of the top heavyweights in the rankings. When Klitschko won the IBF title against Chris Byrd there were four separate heavyweight champions. Since then he has unified the IBF, IBO, WBO & WBA belts and defeated the WBA champion in recess. Following his win over Ruslan Chagaev, Klitschko was awarded the vacant Ring Magazine Heavyweight Title. He works behind a strong left jab and possesses one of the strongest right crosses in boxing.

Klitschko is a safety first fighter; however, he tends to methodically break down his opponents over a series of rounds. Emanuel Steward, Klitschko's trainer, has also pointed out that Klitschko's ability to hurt opponents late on in fights (Tony Thompson, Samuel Peter, etc.) is a sign of his power. He has gone on to say that he feels Klitschko is one of the hardest punchers in heavyweight history.

Klitschko turned professional with Universum Box-Promotion in Hamburg under the tutelage of Fritz Sdunek.

He suffered his first setback after 24 bouts without a loss to journeyman Ross Puritty, who entered the bout with a record of 24–13–1. Wladimir Klitschko's coach, Fritz Sdunek, jumped into the ring and stopped the fight.

On 14 October 2000, in Cologne's Kölnarena (Germany), Klitschko won the WBO Heavyweight Championship from American Chris Byrd. Byrd had previously upset his elder brother Vitali (who pulled out injured during their bout). After five successful defenses of the WBO belt, Klitschko suffered an upset loss to Corrie Sanders. Sanders battered Klitschko for two rounds knocking him out on 8 March 2003, in Hannover, Germany.

Klitschko appeared with Lennox Lewis in the motion picture Ocean's Eleven. He is an avid chess player, kite-surfer, golfer, and humanitarian. Both Klitschko brothers have been involved in charitable activities dedicated to supporting the needs of children around the world. Both brothers have formed their own charities that contribute to children in need in Africa and South America. They won humanitarian awards for their "Fight For Peace" and "Sport for Good" projects in 2002 and 2007.

In 2002, the Klitschko brothers announced that they had agreed to work specifically for UNESCO (the United Nations Educational, Scientific and Cultural Organization), which supports more than 180 projects in 87 countries. Klitschko is also a passionate golfer and was seen playing in the Dunhill Links Championship in Scotland. The tournament was played over three courses in 2008 including St Andrews, Carnoustie, and Kingsbarns in Fife and Angus. Klitschko was named curator of the Ukrainian pavilion at the 2009 Venice Biennale. Klitschko starred in the music video for Chris Cornell's song "Part of Me" in 2008, alongside rising dancer Carlos Kerr Jr. and Method Man.
