Jack Broughton, English boxer (b. 1703)
John "Jack" Broughton (c. 1703 or 5 July 1704 – 8 January 1789) was an English bare-knuckle boxer. He was the first person to codify a set of rules to be used in such contests; prior to this the "rules" that existed were very loosely defined and tended to vary from contest to contest. His seven rules of how boxing would be conducted at his amphitheatre (the largest and most influential at that time) evolved later into the London Prize Ring rules which are widely regarded as the foundation stone of the sport that would become boxing, prior to the development of the Marquess of Queensberry rules in the 1860s.
