The Most Bouts and Wins in a Career: Len Wickwar
This record is quite hard to determine with precise accuracy. In the late 19th and early 20th centuries, boxing was banned outright in some areas as an outlaw sport and had to be presented as “an exhibition” in some others.
So determining the complete records for boxers is not completely possible.
But by combing through newspaper archives with the most accurate database possible, it shows that lightweight Len Wickwar had the most verified professional fights and the most wins in a career.
Between 1928 and 1947, Wickwar compiled a record total of 467 fights which is the records that almost impossible be touched.
The Most Knockouts in a Career: Archie Moore
This is another record that is well out of the scope of contemporary prize possible for fighters. In a career that lasted three decades, “The Old Mongoose” Archie Moore was considered as a top-rated fighter from middleweight to heavyweight and won 183 professional fights, 131/ 183 by stoppage.
Moore was a crafty veteran who grew his power with him as he went up in weight categories. He is arguably considered as the greatest light heavyweight to ever live and has been held the title for the last decade of his career, while ranking at the top of the heavyweight division in his spare time.
Moore is also the only fighter to have competed against both Muhammad Ali and Rocky Marciano.
The Most Titles Held Concurrently in Different Weight Classes: Henry Armstrong
Besides Sugar Ray Robinson, Henry Armstrong is only one truly valid alternative: as the greatest pound-for-pound fighter to ever live. For a short period of time in 1938, Armstrong dominated as the undisputed world champion at 3 divisions of featherweight, lightweight and middleweight, all at the same time. In the time when there was only one world champion per division, Armstrong was the unquestioned king from division of 126 to 147 pounds.
To put that into context, in today’s era of titles and half weight classes, there could be up to 20 “world champions” at any given time, covering the same weight division.
Remarkably, in 1940 Armstrong battled against middleweight champion Cerefino Garcia. A win would have made him a world champion in four divisions during the time when there were only eight divisions.
