In Nigel Kneale's 1996 radio serial "The Quatermass Memoirs", it is revealed that the Professor was first involved in rocketry experiments in the 1930s, and that his wife died young. The unmade prequel serial "Quatermass in the Third Reich", an idea conceived by Kneale in the late 1990s, would have shown Quatermass travelling to Nazi Germany during the 1936 Berlin Olympics and becoming involved with Wernher von Braun and the German rocket programme, before helping a young Jewish refugee to escape from the country. According to "The Quatermass Memoirs", during World War II Quatermass conducted top secret work for the British war effort, which he subsequently refused ever to discuss.
