Dietrich Bonhoeffer was a prisoner at the Nazi Concentration camp at Buchenwald Concentration Camp, Dietrich Bonhoeffer’s fellow prisoner was English officer, Hugh Sigismund Payne Best. After the war, Best wrote to Sabine and Gerhard Leibholz the following about Bonhoeffer:

In fact my feeling was far stronger than these words imply. He was, without exception, the finest and most lovable man I have ever meet.
