Dietrich Bonhoeffer (February 4, 1906 – April 9, 1945) was a German Lutheran pastor, theologian and martyr. He was also a participant in the German resistance movement against Nazism and a founding member of the Confessing Church. His involvement in plans by members of the Abwehr (the German Military Intelligence Office) to assassinate Adolf Hitler resulted in his arrest in April 1943 and his subsequent execution by hanging in April 1945, 23 days before the Nazis' surrender. His view of Christianity's role in the secular world has become very influential. Source
