Larry_Gains--Primo_Carnera

Lawrence Samuel "Larry" Gains (12 December 1900 – 26 July 1983) was a Black Canadian heavyweight boxer who was champion of Canada and the British Empire. One of the top heavyweights of his era, he was denied the opportunity to become World Champion due to the bar on black boxers competing for the title.
Gains was recognized as the World Colored Heavyweight Champion twice in his career, and was the last to be recognized as such when the title became extinct after Joe Louis won the World Heavyweight title on June 22, 1937.
