Details

Admiral Sir Reginald ‘Blinker’ Hall (1870–1943) was the Director of Naval Intelligence throughout the First World War; Room 40 was his Admiralty HQ. In the 1920s, he wrote an autobiography, but it was banned by government order. The parts that have survived, published here with commentary by Philip Vickers, give an absorbing account of Room 40's staff and their top-secret work, including the decryption of the Zimmermann telegram and the interception of Kaisermarine’s cypher system.
