Billy Graham
Charismatic and inspiring, Billy Graham wore down shoe leather to bring Christian conversion to hundreds of thousands of Americans in the 1940s and 1950s, preaching to large crowds such as this one in Columbia, South Carolina. He also migrated onto the radio and television airwaves, using technology to reach even wider audiences. Graham used the Cold War to sharpen his message, telling Americans that “godless communism” was an inferior system, but that democracy in America required belief in God and a constant struggle against “sin.” Photo by John Dominis/Time Life Pictures/Getty Images.
