Four rotor Enigma cypher machine credit (Science Society Picture Library)
{"Image ImageDescription": "A four-rotor German Enigma cypher machine with a second operator display (a 'remote lampboard'), made during World War II. This type of machine, devised by the German Navy in 1939, was used to encode wartime messages requiring a particularly high degree of security. The cracking of German cypher codes by Allied intelligence was a major achievement in cryptanalysis and played a key role in the outcome of the North Atlantic U-boat engagements. The search to crack the the Enigma codes also resulted in ??Colossus??, the first all-electronic digital computer. This rare machine is thought to have been used in the post-war years for coding diplomatic traffic in Switzerland.", "Image Orientation": "Horizontal (normal)", "Image XResolution": "300", "Image YResolution": "300", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "Adobe Photoshop CS Windows", "Image DateTime": "2012:01:25 12:37:14", "Image Artist": "Science Museum", "Image Copyright": "Please read our licence terms.
