AN AMERICAN CONSCIENCE: THE REINHOLD NIEBUHR STORY examines the career and global impact of renowned American-born theologian Reinhold Niebuhr, who became a voice of conscience to a country reaching the pinnacle of its economic and political power. Through archival photos, recordings and interviews with his daughter, former students, The New York Timeswriter David Brooks and civil rights icon Andrew Young, the documentary also explores Niebuhr's influence and impact on numerous leaders, including Martin Luther King, Jr., President Barack Obama, and former President Jimmy Carter. With revealing insights from academic experts who discuss his life and influence, the stories capture Niebuhr's seminal role in American life. Perhaps the clearest indication of the scope of his appeal is the popularity of his Serenity Prayer, most prominently used by Alcoholics Anonymous.
