This photo is of Dietrich Bonhoeffer in Tegel prison, prior to his move to the notorious concentration camp of Buchenwald. Though visits weren’t frequent or long, at Tegel his parents and his fiancé Maria were sometimes allowed to bring him books, such as the one in his hand.

When I mentioned Dietrich Bonhoeffer last week, five people told me they’d like to hear about him. I’m glad to oblige, in this blog and the next.
