Archie “The Old Mongoose” Moore became a champion in the 1950s, but his dominance began in the 1940s. Avoided by many, he fought anyone willing to step in the ring and built a resume full of legends.

In this decade, he earned wins over Lloyd Marshall, Holman Williams, Jimmy Bivins, and Oakland Billy Smith. His style—a mix of power, patience, and guile—made him one of the most avoided fighters of the era.

8) Bob Montgomery

Bob Montgomery was one of the lightweight division’s most dangerous champions during one of its deepest eras. Best remembered for his four-fight series with Beau Jack, Montgomery also clashed memorably with Ike Williams.

He fought at a time when the lightweight class was stacked with elite talent, and his rugged, relentless style earned him respect from peers and fans alike. Montgomery was as tough as they came.

7) Beau Jack

Beau Jack exploded onto the scene in 1942, winning 13 straight fights, including a stoppage victory over Tippy Larkin for the New York version of the lightweight crown.

His rivalry with Bob Montgomery was the stuff of legend, especially their bouts that raised money for World War II bonds, including a 1944 clash that set a record gate at Madison Square Garden. A true crowd-pleaser, Jack’s whirlwind style made him one of the era’s most beloved figures.

6) Manuel Ortiz

Manuel Ortiz was a dominant bantamweight champion, holding the world title for nearly eight years and engaging in 23 title fights. He only failed to beat one opponent during that run and was never stopped in his career.

Ortiz’s skill set included outstanding stamina, slick inside fighting, and textbook fundamentals. Like Joe Louis, he sometimes suffered from a lack of elite opposition, but he demolished nearly everyone put in front of him and proved he could have thrived in any era.

5) Ike Williams

Ike Williams turned professional in 1940 and quickly became one of the most feared lightweights in history. His big breakthrough came in 1945 when he knocked out Juan Zurita to claim the NBA lightweight crown.

He unified the division in 1947 with a KO win over Bob Montgomery. Williams also owns wins over Sammy Angott, Kid Gavilán, Johnny Bratton, and Beau Jack. His mix of punching power and skill defined him as one of the all-time greats at 135 pounds.

4) Joe Louis

The “Brown Bomber” was already a legend before the 1940s, but he cemented his status with 18 wins in 18 fights during the decade. He defended his heavyweight title with consistency and class, beating Billy Conn (twice), Buddy Baer, Arturo Godoy, and Jersey Joe Walcott.

While some criticize the quality of his opposition during this period, Louis’s dominance speaks for itself. He was the face of American boxing and a cultural icon whose shadow stretched far beyond the ring.

3) Ezzard Charles

Cincinnati’s Ezzard Charles may be the most underrated great in boxing history. A brilliant technician, he defeated Archie Moore three times, along with Charley Burley, Jimmy Bivins, Lloyd Marshall, and Elmer Ray.

Though he later became heavyweight champion in 1949 by beating Jersey Joe Walcott, Charles made his name in the 1940s as perhaps the best light heavyweight of all time. His skill, intelligence, and adaptability made him one of the decade’s finest.

2) Willie Pep

Willie Pep’s defensive wizardry made him nearly untouchable. He began the decade with an incredible 73-fight undefeated streak and captured the featherweight crown in 1942 with a win over Chalky Wright.

His rivalry with Sandy Saddler became one of boxing’s greatest storylines, highlighted by their four brutal fights. Pep’s ability to make opponents miss with ease earned him the nickname “Will o’ the Wisp” and a place among the sport’s true legends.

Robinson won the welterweight title in 1946 against Tommy Bell and picked up victories over Henry Armstrong, Kid Gavilán, Fritzie Zivic, and Marty Servo. His blend of speed, power, and skill set the standard for greatness in the sport.
