Entrepreneur and Nazi functionary Fritz Kiehn lived through almost 100 years of German history, from the Bismarck era to the late Bonn Republic. A successful manufacturer, Kiehn joined the Nazi Party in 1930 and obtained a number of influential posts after 1933, making him one of the most powerful Nazi functionaries in southern Germany. These posts allowed him ample opportunity to profit from "Aryanizations" and state contracts. After 1945, he restored his reputation, was close to Adenauer's CDU during Germany's economic miracle, and was a respected and honored citizen in Trossingen. Kiehn's biography provides a key to understanding the political upheavals of the twentieth century, especially the workings of the corrupt Nazi system as well as the "coming to terms" with National Socialism in the Federal Republic.
