At the outbreak of war in September 1939, Doreen Luke was fifteen years old and had just begun work as an apprentice (学徒) in a department store selling clothing and household goods in her hometown of Bodmin in Cornwall. Doreen recalls the first day of war, “My mother was in the process of cooking the Sunday dinner when the Prime Minister announced over the radio that we were at war with Germany… From then on everything changed in our lives. Suddenly there was a different atmosphere.”

During the first years of the war, Doreen was part of a concert party that entertained civilians and service personnel in Cornwall. Although Doreen made effort for the war through her work in entertainment, she was eager to become involved with the war effort in a more direct way, “ My seventeenth birthday came in January 1941. Many of my friends were joining the Forces. I was becoming very restless. In any case soon at the age of eighteen I would be called up to go and work in a factory or to do some other vital war work but that didn’t appeal to me. I was more adventurous than that!”

Realizing that the Women’s Auxiliary Air Force(WAAF)was recruiting (招募) wireless operators, Doreen quickly made up her mind. At the age of eighteen, she received her call-up papers and became a member of the WAAF. After one year’s training, Doreen became a wireless operator at Bletchley Park and began work in the Auto Room. Doreen recalls her first visit to Bletchley and the secrecy essential to her work, “I didn’t realize when I first stepped into that room that I was going to be a part of a very secret department. In fact I didn’t know that until fifty years after the war.”
