Achievements

• Born in Copenhagen, Denmark on May 29, 1883, he won the World Welterweight Championship on January 1, 1916, defeating Ray Bronson in Melbourne, Australia in a twenty round points decision. Prior to his entry into the Olympics, Holberg was a five time amateur champion of Denmark. He qualified for the 1908 Summer Olympics, but was eliminated in the first round after losing to future welterweight world champion Matt Wells. Holberg won on points after 20 rounds, but lost the title only 23 days later to Irishman Tom McCormick. Foreign some reason, McCormick is more often recognized as a world welterweight boxing champion than Holberg.
