Here is just a little bit of information about him. He was an active preacher and author for six decades. Dr. Graham sought to relate the Bible to contemporary social issues. He preached jointly with Dr. Martin Luther King at some crusades in the 1950s. Graham provided some of the bail money to release Dr. King when he was arrested after a civil rights demonstration. It is estimated the total audience at revival meetings, listeners on radio, and viewers on television of Dr. Graham’s messages exceeds two billion people.  This is a PDF from Wikipedia on the life of Dr. Graham.
