Louis held the heavyweight title for 12 years and 10 months, defending it successfully 25 times. His dominance was so absolute that he remained the undisputed king of the division throughout the late 1930s and most of the 1940s.

Robinson is widely considered the greatest pound-for-pound fighter, holding the middleweight title for 7 years but dominating the division for nearly a decade when including his return and unification fights. His technical mastery and ring IQ were unmatched.
