Victor Klemperer risked his life to preserve these diaries so that he could, as he wrote, "bear witness" to the gathering hor-ror of the Nazi regime. The son of a Berlin rabbi, Klemperer was a German patriot who served with honor during the First World War, married a gentile, and converted to Protestantism. He was a professor of Romance languages at the Dresden Technical Institute, a fine scholar and writer, and an intellectual of a somewhat conservative disposition.
