E93 - The GPO and GC&CS

July 2019    Most people now know of the work carried out by Tommy Flowers and his team that ultimately led to the design and construction of ‘Colossus’, the world’s first large-scale electronic digital computer. Flowers worked for the General Post Office at their Research Station at Dollis Hill but that work was just one part of the connection between the GPO and the Codebreakers at Bletchley Park.    With the opening this year of our new exhibition, D-Day: Interception, Intelligence, Invasion, that link with the modern GPO, British Telecom now called BT, continues.   In this episode our research historian, Dr David Kenyon, sat down with the Head of Heritage and Archives for BT, David Hay, to talk about our shared history.   Also in this episode we bring you something very special indeed. In 1981 at the modern equivalent of Dollis Hill, Adastral Park, Tommy Flowers and some of his original team gave a talk about their wartime work and thanks to BT we can bring you highlights of that reunion.     BT is the Sole and Exclusive Corporate Partner of the restoration of Teleprinter Building and the Exclusive and Sole Partner of the Exhibition.   Image: ©BT ref TCB 638/RES 23706-05 Tommy Flowers & Team 1981 reunion     #BPark, #Bletchleypark, #WW2, #DDay75, #BT
