William Harrison \"Jack\" Dempsey was an American professional boxer and a cultural icon of the 1920s. He held the World Heavyweight Championship from 1919 to 1926.

Desperate for the money, Dempsey would occasionally visit saloons and challenge for fights, saying \"I can\'t sing and I can\'t dance, but I can lick any SOB in the house.\" If anyone accepted the challenge, bets would be made. According to Dempsey\'s autobiography, he rarely lost these barroom brawls. A little known fact about Dempsey is that for a short time he was a part-time bodyguard for Thomas F. Kearns, president of The Salt Lake Tribune and son of Utah\'s U.S. Senator Thomas Kearns. The two men remained friends for years afterward.
