Information required about war hero

Iam

in the study of the Second World War and am currently embarked upon a major piece of research into a small group of professional medical personnel in the Royal Army Medical Corps who participated in operations in Nazi-occupied territory.

One of these was a remarkable man called Major Rudolph Stuppel and wonder if readers can help in my search for information about him.

Born in Wales in 1904, Stuppel had been a doctor in peacetime, training in London and working at hospitals in Edinburgh and Yorkshire and as a medical officer in Fiji and Cyprus. After war broke out in 1939 he joined the Royal Army Medical Corps and worked as a surgeon in Sudan and later Tobruk, where, in 1942, he was captured. In 1943 he escaped from a POW camp in Italy and made his way to German-occupied Yugoslavia, where he worked as a doctor with partisans. On 31 October 1943 he was killed in a German aircraft attack.
