Dietrich Bonhoeffer (1906 - 1945) was a major writer and thinker in Germany between the wars. His books of theology are still read and as influential among contemporary evangelical believers as the work of C.S. Lewis and Billy Graham. In 1939 he refused to take the loyalty oath to Adolf Hitler. Shortly after that he was invited to participate in a plot to assassinate Hitler. He was eventually caught, imprisoned, and executed. - Dietrich Bonhoeffer's Prison Poems
