Jem Mace (8 April 1831 – 30 November 1910) was an English boxing champion. He was born at Beeston, Norfolk. Although nicknamed “The Gypsy”, he denied Romani ethnicity in his autobiography. A middleweight, he succeeded in outboxing heavier opponents thanks to his dancing style, clever defensive tactics and powerful, accurate punching.
Mace was a skilful violinist who originally aspired to a career in music. Indeed it was the trashing of his violin by three thugs in Great Yarmouth, Norfolk, and his subsequent beating of them in fistic duels in the street, which led him to enter the prize ring.
