Nikolai Valuev

Nikolai Sergeyevich Valuev, born in 1973, is a Russian politician and former professional boxer who competed from 1993 to 2009 and held the WBA heavyweight title twice between 2005 and 2009. At a height of 2.13 metres (7 feet) and a peak weight of 151 kilograms (333 pounds), he is best known as the tallest and heaviest world champion in boxing history. He was also the first heavyweight champion to finish his career without ever being knocked down, and the fifth to have never been stopped. His size made him one of the most recognisable heavyweights of the 2000s, and after his boxing career he entered politics in Russia.
