Bob KO Sweeney

Boxer John Kraynak (December 15, 1894 in Plymouth, Pennsylvania – June 14, 1961 in Wilkes-Barre, Pennsylvania, United States) used the name Bob "KO" Sweeney because it was a more "Irish-sounding" name that would result in a bigger draw for his fights. He is perhaps best known for his bout against Bob Fitzsimmons, for it is believed by some to be the first bout ever captured on film. However, Fitzsimmons fought Sweeney in 1914, and boxing films had first been made almost 20 years before this (including Fitzsimmons' 1897 fight against Jim Corbett!), proving this belief to be an obvious fallacy.
