Krystyna Wituska was born to an affluent Polish family and educated in Switzerland. When the Germans invaded Poland in World War II, her family fled their estates for Warsaw. Krystyna got a job and also went to work for the Polish Resistance movement. Because of her fluency in German, she was assigned to collect intelligence about Wehrmacht activities. In 1942, at age 21, she was arrested by the Gestapo. She was transferred to a prison in Berlin and executed in Halle two years later. In the last year of her life, she wrote letters that were smuggled out to her parents. The letters were collected and published in Poland in 1970. In 1998, an English language edition appeared, entitled I Am First a Human Being. The letters were published again in English in 2006 as Inside a Gestapo Prison.
