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 "e;Aryanizations"e; 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 "e;coming to terms"e; with National Socialism in the Federal Republic.
