Boxer Jake LaMotta, whose life was depicted by Robert De Niro in the film "Raging Bull," has died at the age of 95, according to a report from The Associated Press.

Denise Baker, LaMotta's fiancee, told the AP that he died Tuesday at a hospital in the Miami area from complications of pneumonia.

LaMotta, nicknamed the "Bronx Bull," fought to a record of 83-19-4 with 30 knockouts during his career from 1941 to 1954.

He fought Sugar Ray Robinson six times, giving Robinson his first defeat on Feb. 5, 1943, in what was their second fight. He would lose the rematch to Robinson to 21 days later.

He ultimately lost five out of the six fights with Robinson, including their final match on Feb. 14, 1951, which became known as the St. Valentine's Day Massacre. LaMotta took a beating during the fight, which was eventually stopped by technical knockout in the 13th round, but was never knocked down.

Before losing to Robinson the final time, he had held the middleweight title on June 16, 1949, when Marcel Cerdan couldn't continue following the 10th round.

LaMotta was portrayed by De Niro in Martin Scorsese's 1980 film "Raging Bull," which was based off his memoir. De Niro won the Academy Award for Best Actor for his performance, one of eight Oscar nominations for the film.
