Rev. William Sloane Coffin, Jr. (June 1, 1924 – April 12, 2006) was a liberal Christian clergyman and long-time peace activist with international stature. He was ordained in the Presbyterian church and later received ministerial standing in the United Church of Christ.
In his younger days he was a superb athlete, a highly talented pianist, a CIA agent, and later chaplain of Yale University, where the influence of Reinhold Niebuhr's social philosophy led him to become a leader in the civil-rights and peace movements of the 1960s and 1970s.
He went on to serve as Senior Minister at the Riverside Church in New York City, and President of SANE/Freeze (now Peace Action), the nation's largest peace and justice group, and prominently opposed United States military intervention from the Vietnam War to the Iraq War. He was also an ardent supporter of gay rights.
