Slapsie Maxie Rosenbloom was World Light-Heavyweight Boxing Champion from 1930 to 1934. He was the busiest title holder in ring history, fighting 106 times during his four-and-a-half-year reign—the equivalent of fighting one bout every 15 days!

Rosenbloom decisioned World Champion Jimmy Slattery to win the Light-Heavyweight title on June 25, 1930. He lost the crown to Bob Olin by decision on November 16, 1934.

Journalist Damon Runyon, writing about Rosenbloom’s colorful persona and unique open glove style of boxing, dubbed him Slapsie Maxie, a nickname that followed him throughout his boxing career. Upon retirement from the ring, Rosenbloom’s sharp wit and broken syntax brought him new success in motion pictures. He appeared in nearly 100 films during his post-boxing career.

His professional boxing record, which began in 1923 and closed in 1939: 299 bouts—won 223 (19 KOs), lost 42, drew 32, 2 no-contests.

Rosenbloom was elected to the Boxing Hall of Fame in 1972 and to the International Boxing Hall of Fame in 1993.
