The career knockout record, most often cited as 131. It is the highest in the recorded history of boxing and is not seriously threatened.
The wait
Moore turned professional around 1935 and was not given a world title opportunity until 17 December 1952, when he beat Joey Maxim for the light heavyweight championship.
He was thirty-six by his own account, and possibly older. He had campaigned publicly for years for a shot, including through letters to the press.
The defence
His cross-armed guard, sometimes called the armadillo, kept his forearms high and crossed, offering almost no target.
It allowed him to compete at the top level into his late forties with unusually little accumulated damage.
Marciano, 1955
On 21 September 1955 Moore challenged Rocky Marciano for the world heavyweight title at Yankee Stadium.
He knocked Marciano down in the second round. Marciano recovered and stopped him in the ninth. It was Marciano's final fight.
Clay, 1962
On 15 November 1962 Moore fought the twenty-year-old Cassius Clay in Los Angeles and was stopped in the fourth.
Moore had briefly trained Clay, and the arrangement ended over Clay's refusal to do chores at the camp.
The age
Moore gave his birth year as 1916; his mother stated 1913. He never conceded the point.
After
He trained George Foreman, including for the 1974 fight in Kinshasa, and ran youth boxing programmes in San Diego for decades. He died in 1998.
Why it goes on a wall
Because the sport is built on the idea that the moment arrives when you are young, and he was refused it for seventeen years and then held the title for nine.
