He rose to fame after he started hosting the annual Billy Graham Crusades on TV in 1947, which he continued until his retirement in 2005.
Rev Graham promoted racial integration and once preached alongside Martin Luther King Jr in New York in 1957.
He was the first noted evangelist to take his message behind the Iron Curtain.
William Martin, author of ‘A Prophet With Honor: The Billy Graham Story’, said: “He was probably the dominant religious leader of his era.
“No more than one or two popes, perhaps one or two other people, came close to what he achieved.”
