1. Henry Armstrong (151-21-9, 101 KO)
Henry Armstrong was a spark plug of a fighter whose fists would pump like pistons as he ran though opponent after opponent as a welterweight challenger and champion.
Unsatisfied with the lack of attention to smaller fighters despite his amazing run in 1937 to the featherweight title, 1938 was the year that Armstrong became the only fighter in boxing history to hold three titles simultaneously; the Featherweight, Lightweight and Welterweight titles.
Upsetting the “Welterweight title Jinx of the 30’s,” which saw 12 previous champions fail, Armstrong was the only champion to defend the welterweight title 19 times, a feat that is still unsurpassed today. He also amassed a knockout streak that reached 27, which remains 10th on the all-time list.
Over his career he faced 17 Hall of Fame fighters, defeating 15 of them. Armstrong remains the greatest welterweight fighter we’ve seen in the sport of boxing.
