Dietrich Bonhoeffer (1906 – 1945) A German pastor, theologian, and leading member of the Confessing Church, Bonhoeffer is best known for his staunch resistance to Nazism. After earning doctorates in theology at Berlin and studying in New York, he returned to Germany, helped found an underground seminary, and became involved in the military-intelligence plot to overthrow Hitler. Arrested in April 1943, he was hanged at Flossenbürg concentration camp on 9 April 1945. His writings—The Cost of Discipleship, Life Together, and Letters and Papers from Prison—continue to inspire Christian ethics and non-violent resistance movements worldwide.
