William Franklin Graham Jr. (November 7, 1918 – February 21, 2018) was an American Christian Evangelist and an ordained Southern Baptist minister who became widely known internationally after 1949. He has been referred to as one of the most influential preachers of the 20th Century. He held large indoor and outdoor rallies with sermons which were broadcast on radio and television, some are still being broadcast well into the 21st century.
In his six decades of television, Graham hosted annual Billy Graham Crusades, which ran from 1947 until his retirement in 2005. He also hosted the popular radio show Hour Of Decision from 1950 to 1954. He repudiated segregation and, in addition to his religious aims, helped shape the worldview of a huge number of people coming from different backgrounds leading them to find a relationship between the bible and contemporary secular viewpoints.
Graham preached to live audiences of nearly 215 million people in more than 185 countries and territories through various meeting. He also reached hundreds of millions more through television, video, film and webcasts.
Billy Graham was a spiritual adviser to American presidents and provided spiritual counsel for every president from Harry Truman to Barack Obama. He was particularly close to Eisenhower and Lyndon B Johnson. He insisted on racial integration for his revivals and crusades in 1953 and invited Martin Luther King to preach jointly at a revival in New York City in 1957.
Graham also bailed King out of jail in the 1960s after King was arrested at a demonstration in the 1960s. He was also lifelong friends with the founding pastor of the Crystal Cathedral Robert H Shuller, whom Graham persuaded to start his own television ministry.
As of 2008, Graham's estimated lifetime audience, including radio and television broadcasts, topped 2.2 billion and because of his crusades, Graham preached the gospel to more people in person than anyone in the history of Christianity.
