Jim Jeffries
“The Boilermaker”
Inductee No. 006
Biography & Career Overview
James Jackson Jeffries was born on April 15, 1875, in Carroll, Ohio, and grew up in the Los Angeles area. His work as a boilermaker supplied his famous nickname. He developed into a formidable heavyweight through powerful punching, exceptional endurance and experience against leading fighters of his era.
Jeffries fought from a crouch, using an extended left hand to set up damaging punches. Trainer Tommy Ryan helped refine the style. His ability to remain dangerous late in long contests became a defining feature of his championship career.
Historical record: The International Boxing Hall of Fame lists 18 wins, 1 loss and 2 draws, with 15 knockouts. Historical compilations differ.
Championship: World heavyweight champion from 1899 to 1905, with seven successful defenses listed by BoxRec.
Retirement: He retired undefeated in 1905 after making his final defense in 1904. His only defeat came during his 1910 comeback.
Championship-Winning Fight: Bob Fitzsimmons, June 9, 1899
At Coney Island in Brooklyn, Jeffries challenged the experienced champion Bob Fitzsimmons. Although Fitzsimmons was favored, Jeffries repeatedly knocked him down before finishing the contest with an eleventh-round knockout. At 24, Jeffries became world heavyweight champion.
Biggest Fight: Jack Johnson, July 4, 1910
Jeffries’ most historically significant fight was his comeback against Jack Johnson in Reno, Nevada. At 35, nearly six years after his last professional contest, Jeffries challenged the reigning champion. Johnson controlled the fight and stopped him in the fifteenth round, ending his unbeaten record.
Promoted as the “Great White Hope,” Jeffries publicly supported reclaiming the championship for white fighters. The contest carried enormous racial significance, and Johnson’s victory was followed by celebrations and racist violence across the United States. It became known as the “Fight of the Century.”
