Robert Gordon Switz
Robert Gordon Switz was reported to be a "wealthy American convert to communism". He was arrested in Christmas of 1933 in France. His role in espionage was to "gather French defense information for the benefit of Soviet intelligence". He escaped prosecution by cooperating with investigators from La Sûreté nationale. His arrest led to the unraveling of an espionage network that included Lydia Stahl. Most of the information collected concerned French armaments, and was a form of industrial espionage.
