The Breaking of the Enigma - The Cyclometer Machine

This year marks the 90th anniversary of the first breaking of the Enigma Code by three Polish mathematicians: Marian Rejewski, Jerzy Różycki, and Henryk Zygalski - on the 31st of December 1932, Marian Rejewski was able to decipher and read messages sent by the German coding machine Enigma for the first time. In this short 9 minute film, Dr Tim Flack and Hal Evans from the Department of Engineering at the University of Cambridge talk about the cyclometer machine, the first machine used for code breaking by Marian Rejewski, which they reconstructed at Kings College Cambridge on the basis of sketches made by Rejewski. The machine is the world’s only known replica. The original machine was destroyed just before the outbreak of WWII to prevent the Germans finding out that the Enigma had been broken. This film was produced by the Polish Cultural Institute. #enigma #cryptography #wwii The film is one of two films about the Breaking of the Enigma. Also, have a look at our first one, a 23-minute interview with Alan Turing's nephew Dermot Turing about the origins and purposes of the famous Enigma machine. He explains how the machine worked and why the German military came to adopt it in the 1930s, as well as the critical contribution of the Polish codbreakers to its deciphering and how Polish intellgence helped to inform a later collaboration between the Polish, British and French military intellgience teams on the breaking of further Enigma codes during WWII.    • The Breaking of the Enigma - An Inter...
