of the Federal Republic of Germany in 1963. In 1964 he became President of the German Institute for International and Security Affairs, the German government's main think tank in international relations. He was the father of Brigadier General Hans Helmut Speidel and the father-in-law of European Commissioner and liberal politician Guido Brunner. A German Army military base, the General Dr Speidel Barracks, was named in his honour in 1997. Early career Speidel was born in Metzingen. He joined the German Army in 1914 at the outbreak of the First World War and was quickly promoted to second lieutenant. During the war he was a company commander at the Battle of the Somme and an adjutant. He stayed in the German Army during the interwar period and also studied history and economics at different universities. In 1926 he received his Ph.D. degree in history magna cum laude.

Model was not in. Speidel never did pass on the order to his superior. 20 July Plot Speidel, a professional soldier and nationalist conservative, agreed with those aspects of Hitler's policy that returned Germany to its place as a world power, but disagreed with the Nazis' racial policies. He was involved in the 20 July Plot to kill Hitler and had been delegated by anti-Hitler forces to recruit Rommel for the conspiracy, which he had cautiously begun to do prior to Rommel's injury in a British strafing attack on 17 July 1944. Speidel managed to become Rommel's confidant, purely by chance:
