| | Bletchley Park Part 11 Lorenz, Tunny, Robinson, Colossus, H Block and Hut 11 |
 | | Max Newman, a mathematician working at Bletchley, believed that it would be possible to automate some parts of the process for finding the settings. |
 | | This would involve using two loops of paper tape, the first containing the original message to be decoded and the second containing a repeating pseudo random sequence. |
 | | A suitable machine, known as ‘Heath Robinson’, after the quirky cartoonist/designer, and also as a ‘Tunny Rack’, was designed at Newman’s request by TRE in Malvern and built by the Post Office Research Laboratories at Dollis Hill, London. |
