The Lorenz Machine:
Ultra, an Allied intelligence project, devised methods and created machines to decipher military codes and ciphers that were being used by the Axis powers. Among these cipher machines the Axis powers used, the two most important are the Enigma machine and the Tunny machine (also known as the Lorenz machine). These machines allowed for communication among the Axis countries so they could speak about their military plans in code. On July 25, 1939, the Polish handed over Enigma machines and their techniques for decrypting ciphers to their French and British allies. Ultra was then eventually assembled and created intricate machines, the Bombe and the Colossus, to decode these messages and use this military intelligence to the Allies’ advantage. Overall, Ultra essentially gave insight into Germany’s military plans before they were implemented, allowing for more beneficial decisions to be made and more lives to be saved, while making sure this project stayed top secret. Ultra helped the Allies win their ultimate victory, and it is estimated that it shortened the war by two to four years.
Developed during WWII by Alan Turing and Gordon Welchman; Helped decrypt German Enigma code
Designed by Tommy Flowers;
Used to decrypt the codes of the German Lorenz SZ-40 cipher machine
