Giacobbe "Jake" LaMotta (born July 10, 1921) is an American retired professional boxer and former World Middleweight Champion. Nicknamed "The Bronx Bull" and "The Raging Bull," LaMotta was a rough fighter, who although not particularly a big puncher, would subject his opponents to vicious beatings in the ring, with use of constant stalking, brawling and inside fighting, he developed the reputation for being a 'bully', and is often referred to today as a swarmer and a slugger. Due to his style of fighting, LaMotta often got as much as he was given in an era of great middleweights; with a thick skull and jaw muscles, LaMotta was able to absorb incredible amounts of punishment over the course of his career, and is thought to have one of the greatest chins in boxing history. LaMotta's six fight rivalry with Sugar Ray Robinson is one of the most notable in the sport, with LaMotta winning just one of the bouts, although each one was close and LaMotta dropped Robinson multiple times. LaMotta, who has lived a turbulent life in and out of the ring, was portrayed by Robert De Niro in the 1980 film Raging Bull.
