[tps_header]8. Jack Dempsey[/tps_header]
Known as the “Manassa Mauler”, Jack Dempsey (61-6-9, 50 KOs) was born in Manassa, Colorado and enjoyed two reigns as Heavyweight champion of the world.
Dempsey was known for his devastating punching power and for advancing the popularity of the sports. A cultural icon, Dempsey’s clash with George Carpentier generated the first million dollar gate in boxing history (per Wikipedia).
In one of his most infamous bouts, Dempsey defeated Jess Willard in three rounds, knocking him down seven times in the first round. The bout has been the subject of criticism because it was alleged that Dempsey had loaded gloves.
