We’re saddened by the passing of Ruth June Bourne, a Bletchley Park Bombe operator whose secret work breaking Enigma was vital to Allied victory. Her legacy is part of GCHQ’s history. Our thoughts are with her loved ones.
It is with great sadness that we share the news of the passing of Ruth Bourne. Ruth served in the Women’s Royal Naval Service (WRNS) during World War Two and worked as a Bombe operator and checker at Eastcote and Stanmore, both outstations of Bletchley Park, from 1943 to 1945.
