The GPO and Bletchley Park:
During wartime in Letchworth,
Margaret Davies worked on the CANTAB project to machine
vital components for the Turing Welchman Bombe. In London,
Tommy Flowers (MBE) of the General Post Office’s (GPO)
research group devised Colossus, the world’s first
programmable electronic computer, which broke the German
Lorenz codes. Guided by the GPO these technologies were
delivered to the codebreakers at Bletchley Park, ultimately
bringing an early end to the war. As a government department
it was not surprising that the GPO created an engineering
training centre at Bletchley Park after the codebreakers had
moved out. This photobook delves into the many GPO
connections with the Park, past and present, tracing the
remnants of the buildings and the rebuilds of the wartime
machines. |

 |
Extended edition [Nov 2020].
"I have just received your book on 'The GPO and
Bletchley Park.' It has some great pictures, stories and
historic events that have taken place there over the
decades. I remember when I was there in 1977 it was still a
very secret place, you were aware that something incredible
had happened in the past, but not sure exactly what that
was. Thanks again for putting more light on this momentous
event in Britain's history."
