In World War II, an ornate Victorian mansion overlooking the River Thames at Medmenham was the Headquarters of the Allied Central Interpretation Unit. It was here that the air photography, obtained by reconnaissance aircraft flying over the whole of enemy and occupied Europe, was analyzed by Photographic Interpreters; the Intelligence produced from their reports influenced virtually every Allied operation during the war. An analytical mind, curiosity, the ability to search for clues and recognize the unusual were essential qualities for the Interpreters and found in men and women from scientific and artistic backgrounds. Women made up half of the work force. Now the women of Medmenham tell the story of their wartime life and work—in their own words.
