Dr. Friedrich Wilhelm Hack is famous for his attempt at peacemaking between Japan and the United States in Switzerland at the end of the Second World War. But he cut a figure not only as a peace-maker, but also as a Key player in Japanese-German naval relations in the 1930's. The aim of this article is to reconstruct the life of Friedrich Hack as for as possible and thereby to shed light on the not well known role of the Imperial Japanese Navy in Japan's policy toward Germany between the two World Wars.
Dr. Hack, who was taken POW by the Japanese at the siege of Tsingtao in 1914, became a weapons broker after the First World War and became influential in Japanese-German aero-naval relations, because the Japanese Navy was interested in acquiring German advanced technology, for example U-Boat and war planes, while Germany maintained the level of weapon-technology that was prohibited by Versailles Treaties by selling them to Japan.
After the Nazi seizure of power Hack's activity expanded into the sphere of foreign policy. His influence upon Japan absorbed the attention of Admiral Wilhelm Canaris, the chief of the intelligence department of the German armed forces, and Joachim v. Ribbentrop who intended to bring about better relations with Japan. So Hack played the role as the initiator of “Anti Comintern Pact”. But his success brought conflicts with the Nazi Party and others in “National Socialistic Polycracy” and resulted in his arrest.
Through the help of the Japanese Navy, Hack could live the life of an exile in Switzerland after the outbreak of the Second World War and served as an informant for the Japanese Navy. This activity of Hack led to the peace-mediation between the Japaneses Navy and the U. S. Office of Strategic Services.
Friedrich Hack symbolizes a aspect of Japanese-German naval relations in the 1930's and the early 1940's.
