Nicola Adams has become the first British boxer to retain an Olympic title since Harry Mallin in 1924.
Mallin, a middleweight from Shoreditch, won his first Olympic title in 1920 at the age of 28, and repeated the feat four years later.
Mallin need nine bouts to complete his double-winning feat, and his path into history was not without controversy.
In his second bout in 1920, his opponent, American Samuel Lagonia, was disqualified for persistent holding, a decision which so enraged the Americans they threatened to withdraw their entire team from the Games.
And in his 1924 bout with Roger Brousse, Mallin initially dropped the decision, only for it to be reversed when he pointed out that the Frenchman had persistently bitten him during the contest.
