Robert James "Bob" Fitzsimmons (26 May 1863 – 22 October 1917) was a British born professional
boxer who made boxing history as the sport's first three-division
world champion. He also achieved fame for beating
Gentleman Jim Corbett, the man who beat
John L. Sullivan and is in
The Guinness Book of World Records as the lightest Heavyweight Champion. Nicknamed "Ruby Robert" and "The Freckled Wonder", he took pride in his lack of scars and appeared in the ring wearing heavy woollen underwear to conceal the disparity between his trunk and leg-development. He was also known for his pure fighting skills due to dislike of training for fights, which would ultimately cost him at times in his career.
