World Featherweight Champion in 1925 and 1926, Louis “Kid” Kaplan defended his crown only three times before outgrowing the Featherweight Division. Kaplan won the vacant featherweight title with a nine-round TKO over Danny Kramer in Chicago on January 2, 1925. He was undefeated in his next 16 fights but relinquished his crown on July 6, 1926.
After vacating his title, the 54 Kaplan was often referred to as the Uncrowned Lightweight Champion, a compliment given him after top lightweight fighters of the era, such as Tony Canzoneri, Al Singer, and Al Mandell, refused to fight him and his punishing style.

Kaplan’s pro record: 150 bouts—won 108 (26 KOs), drew 13, lost 17, no-contests 12.
