Background: Robert James Fitzsimmons was born on 26 May 1863 in Helston, Cornwall, England, the youngest of seven boys and five girls born to James and Jane (nee Strongman) Fitzsimmons. Not long before his birth, his parents had moved from his father's native Ireland to Cornwall, where his mother came from, in order for his father to find work as a policeman. Fitzsimmons received his early education at the National school in Helston. In 1873, the family moved again; James, Jane and their youngest five children sailed on the Adamant for the 93 day journey to Lyttelton, New Zealand.
Context: In 1896, Fitzsimmons won a disputed version of the World Heavyweight Championship in a fight in Langtry, Texas, against the Irish fighter Peter Maher. On 17 March 1897, in Carson City, Nevada, he knocked out American Jim Corbett, generally recognised as the legitimate World Heavyweight Champion (having won the title from John L. Sullivan in 1892) in round 14. This constituted a remarkable achievement, as Jim Corbett, a skilled boxer, weighed one stone 3 pounds (17 lb) more than Fitzsimmons. He out-boxed Fitzsimmons for several rounds, knocked him down in the sixth round and badly damaged his face with his jab, left hook and right hand, but Fitzsimmons kept coming and Corbett began to tire. In the 14th round, Fitzsimmons won the title with his "solar plexus" punch. Corbett collapsed in agony. Fitzsimmons' "solar plexus" punch became legendary, although he himself may never have used the phrase. The entire fight was filmed by Enoch J. Rector and released to cinemas as The Corbett-Fitzsimmons Fight, the longest film ever released at the time. Using her maiden name, it was covered by Nellie Verrill Mighels Davis, the first woman to report a prize fight.  Fitzsimmons spent the rest of 1897 and 1898 doing stage tours. In 1899, Fitzsimmons fought James J. Jeffries at the Coney Island Athletic Club near Brooklyn, New York. Most people gave Jeffries little chance, even though at over 15 stones (95 kg) he massively outweighed his opponent and was far younger, but Jeffries lifted the World Heavyweight Champion from Fitzsimmons with an 11th-round knockout.  In June 1901 Fitzsimmons took part in a wrestling match against Gus Ruhlin. He lost and went back to boxing. He then enjoyed legitimate boxing knockouts of leading contenders Ruhlin and Tom Sharkey.  In 1901 he published a book Physical Culture and Self-Defense (Philadelphia: D. Biddle). In 1902, he and Jeffries had a rematch, once again with the World Heavyweight Champion at stake. Fitzsimmons battered Jeffries, who suffered horrible punishment. With his nose and cheek bones broken, most would have sympathized with Jeffries had he quit, but he kept going until his enormous strength and youth wore down Bob and he knocked him out cold in round eight.
