E179 - Dollis Hill Days

May 2025 During World War Two, Bletchley Park collaborated with several external engineering institutions in developing the famous codebreaking machines, such as the Bombes and Colossus. One such institution was the Post Office Research Station at Dollis Hill in London. In 2022, the previously secret war diary of the Research Station were released online to the public by BT, the successor to GPO Telecommunications. In this episode we are joined by James Elder, an archivist from BT Group Archives, as well as our own Research Historian, Dr David Kenyon, to find out what information the diaries can reveal about this secret collaboration. Many thanks to Dr Ben Thomson for voicing extracts from the War Diary. Image: © Courtesy of BT Group Archives (TCB 473/P 5105) , , , , , ,
