William Franklin Graham Jr. (; November 7, 1918 – February 21, 2018) was an American evangelist, ordained Southern Baptist minister, and civil rights advocate, whose broadcasts and world tours featuring live sermons became well known in the mid- to late 20th century. Throughout his career, spanning over six decades, Graham rose to prominence as an evangelical Christian figure in the United States and abroad. According to a biographer, Graham was considered "among the most influential Christian leaders" of the 20th century. Beginning in the late 1940s and early 1950s, Graham became known for filling stadiums and other massive venues around the world where he preached live sermons; these were often broadcast via radio and television with some continuing to be seen into the 21st century. During his six decades on television, Graham hosted his annual "crusades", evangelistic live-campaigns, from 1947 until his retirement in 2005. He also hosted the radio show Hour of Decision from 1950 to 1954. He openly repudiated racial segregation, at a time of intense racial strife in the United States, insisting on racial integration for all of his revivals and crusades, as early as 1953. He also later invited Martin Luther King Jr. to preach jointly at a revival in New York City in 1957. In addition to his religious aims, he helped shape the worldview of a huge number of people who came from different backgrounds, leading them to find a relationship between the Bible and contemporary secular viewpoints. According to his website, Graham spoke to live audiences consisting of at least 210 million people, in more than 185 countries and territories, through various meetings, including BMS World Mission and Global Mission event. Graham was close to US presidents Dwight D. Eisenhower, Lyndon B. Johnson (one of his closest friends), and Richard Nixon. He was also lifelong friends with Robert Schuller, another televangelist and the founding pastor of the Crystal Cathedral, whom Graham talked into starting his own television ministry. Graham's evangelism was appreciated by mainline Protestant denominations, as he encouraged mainline Protestants, who were converted to his evangelical message, to remain within or return to their mainline churches. Despite early suspicions and apprehension on his part towards Catholicism—common among contemporaneous evangelical Protestants—Graham eventually developed amicable ties with many American Catholic Church figures, later encouraging unity between Catholics and Protestants. Graham operated a variety of media and publishing outlets; according to his staff, more than 3.2 million people have responded to the invitation at Billy Graham Crusades to "accept Jesus Christ as their personal savior". Graham's lifetime audience, including radio and television broadcasts, likely surpassed billions of people. As a result of his crusades, Graham preached the gospel to more people, live and in-person, than anyone in the history of Christianity. Graham was on Gallup's list of most admired men and women a record-61 times. Grant Wacker wrote that, by the mid-1960s, he had become the "Great Legitimator", saying: "By then his presence conferred status on presidents, acceptability on wars, shame on racial prejudice, desirability on decency, dishonor on indecency, and prestige on civic events."
