The Military

Rambo Tribble writes England has awarded Raymond Roberts, one of the nine cryptanalysts responsible for breaking the Nazi Tunny code machine, (also known by the German designation Lorenz cipher machine) the MBE. Roberts is the last surviving member of the team which cracked the German army’s cipher machine functionality, much like others at Bletchley broke the better-known Enigma machine.”

nk497 writes “A single photograph, scraps of circuit diagrams drawn from memory and a pile of disused components – it isn’t much to go on, but from such meager beginnings, engineers rebuilt one of the precursors to the modern computer. The Tunny decryption machine – on display at The Museum of National Computing at Bletchley Park, Buckinghamshire in the UK – was a feat of engineering both during World War II when it was created, and over the past five years when it was rebuilt by retired BT engineers.”

Tunny Code-Breaker Rebuilt At Bletchley Park

Jack Spine writes “Engineers at the National Museum of Computing at Bletchley Park have rebuilt the Tunny machine, a key device used in decoding German High Command messages during the Second World War. The Tunny machine took a team of three people three years to rebuild. At the end of the war, Tunny machines were broken up and the components recycled, while the original circuit diagrams were destroyed or hidden. The team had to piece together plans for the machine from odd pieces of circuit diagram that had been squirreled away by engineers, as well as from the recollections of some of the original builders.”
