German admiral. He was present in W.O.I. at the time of the destruction of the 'Dresden' at the Battle of the Falkland Islands. After W.O.I, he was indirectly involved in the murders of Karl Liebknecht and Rosa Luxemburg, and in other far-right activities. From 1935 to 1944 he was head of the German military intelligence service, the 'Abwehr'. Like many German soldiers, he was very conservative, but he was critical of Hitler and National Socialism. After the failed assassination attempt on Hitler in July 1944, he was relieved of his duties and arrested. On April 9, 1945, shortly before the arrival of the Allies, he was hanged in the Flossenburg concentration camp.
