Wladimir Klitschko is a renowned heavyweight professional boxer from Ukraine, who dominated the ring from 1996 to 2017. During his amateur career, he won the super-heavyweight gold medal at the 1996 ‘Summer Olympics’ at Atlanta, Georgia, defeating Paea Wolfgramm of Tonga. He turned professional under the guidance of German professional-boxing trainer Fritz Sdunek and had a straight run of 24 wins with 22 knockouts, till he suffered his first defeat against American boxer Ross Puritty. He was known for his knockout punch, using a strong jab, straight right hand, and left hook, coupled with great mobility and footwork. Wladimir and his brother, Vitali, are the only two brothers to hold all the world heavyweight titles between them, simultaneously. Having been a two-time world heavyweight champion and having held the ‘World Boxing Association’ (WBA), the ‘International Boxing Federation’ (IBF), the ‘World Boxing Organization’ (WBO), the ‘International Boxing Organization’ (IBO), the ‘Ring’ magazine, and the lineal titles, he announced his retirement from professional boxing in August 2017, ending a career of 64 wins from 69 bouts with 53 knockouts. After a divorce from his first wife, he is now in a steady relationship with American actor, Hayden Panettiere, with whom he has a daughter. Though the Klitschko era has ended, Wladimir remains a heavyweight-boxing legend, who will always be remembered.
