Hey guys, I'm trying to dig up some information on a German officer by the name of Von Oppenheim. Based upon the description I have of him, I am certain that he is part of the famous Von Oppenheim banking family from Cologne. I've checked around and have narrowed it down to this man Waldemar Von Oppenheim, but I need to verify that he was in the German army in WWI. His uncle Max Von Oppenheim was a famous archeologist and was involved in espionage in the East, particularly in India. The Von Oppenheim I am searching for was described as "young' which fits for Waldemar as he was born in 1894 which would've made him 24 in 1918. A Captain Von Oppenheim interrogated a RFC pilot I am researching after he was shot down and captured. Any ideas on where I could search for this Captain Von Oppenheim??
