John Haynes Holmes (1879-1964) was a prominent Unitarian minister and pacifist, noted for his anti-war activism. He actually left the American Unitarian Association (AUA) in 1918 over differences in attitude towards World War I, but continued to preach at his church which retained its AUA membership and accepted membership again right before the Unitarians and Universalist churches merged. He graduated from Harvard in 1902 and then Harvard Divinity School in 1904. He married Madeleine Baker. They had two children, Roger and Frances. He helped found the National Association for the Advancement of Coloured People (NAACP) in 1909 and was a founder and later chair of the American Civil Liberties Union (ACLU). He was a recipient of the Gandhi Peace Award. His works include: A Statement: On the Future of this Church (1919) and Heroes in Peace (1920).
