Legendary pugilist John L. Sullivan was born in Roxbury, Massachusetts, on October 15, 1858. Known to 19th-century boxing fans as the “Boston Strong Boy,” Sullivan became a towering figure in sports history as the first heavyweight champion of gloved boxing and the last undisputed heavyweight champion under London Prize Ring, or bare-knuckle, rules.
A cultural icon of his era, Sullivan is widely regarded as America’s first true sports superstar. His 75-round victory over Jake Kilrain in 1889 remains the last heavyweight title bout fought under London Prize Ring rules. Three years later, he relinquished the heavyweight crown to “Gentleman Jim” Corbett, who defeated him in 21 rounds under Queensberry rules in New Orleans on September 7, 1892.
This archival image preserves the likeness of a man who bridged the gap between raw bare-knuckle prizefighting and the modern sport of boxing.
