Heath Robinson (codebreaking machine)

Heath Robinson was a machine used by British codebreakers at the Government Code and Cypher School at Bletchley Park during World War II in cryptanalysis of the Lorenz cipher. This achieved the decryption of messages in the German teleprinter cipher produced by the Lorenz SZ40/42 in-line cipher machine.
