New York-born Ben Jeby was World Middleweight champion in 1933. He won his title on January 13, 1933 in a 12-round TKO over Frankie Battaglia.

Following several successful title defenses, Jeby lost the Middleweight crown via KO to Lou Brouillard on August 9, 1933.

Jeby had his first pro fight in 1927 at the age of 17, but didn't get a crack at the title until five-and-a-half years later, when reigning World champion Marcel Thil vacated his middleweight crown.

Jeby fought 73 pro fights, winning 54 (22 by KO), drew 4, lost 14 (I2 by KO), 1 no contest.
