American weightlifter John Davis is a double Olympic gold medallist.

He won the over-82.5kg title at London 1948 and then the over-90kg title four years later in Helsinki.

Davis was undefeated between 1938 and 1953, a remarkable 15-year streak which also saw him win seven world titles, the Pan American Games gold medal in 1951 and 11 national crowns.

He was the first person to clean and jerk more than 400lbs and the second to post a combined total of more than 1,000lb.

His only defeat before retirement came at the 1953 World Championships when he was struggling with a thigh problem.

At one stage Davis held all of the world records in his heavyweight class.

He went on to work in the prison service before his death in 1984.
