This two-part class is based on the earlier Enigma lecture with the addition of the more secret and complex Nazi teletype-based encryption system, Lorenz. The Lorenz was developed in the later years of the war and primarily used by the highest levels of the Reich. These machines have millions of possible settings, so the Germany considered them both to be completely secure, but they were not. The analysists who broke the Enigma and Lorenz codes and engineers who designed and built the devices to help break them is a fascinating story. The very secret Colossus built to break Lorenz is considered the first programable computer, though it was not credited as such until it was declassified decades later. This class will discuss the similarities and differences in these two systems, how they were used by the Nazis, and the organization that broke the codes. If you attended the Enigma lecture, come back for a refresher and to hear the rest of the story. Some Title Alert
