Hermann Erben (* 15 November 1897; † 1985) was an Austrian physician who served in the German military intelligence.
He then studied medicine at the University of Vienna, and got a Scholarship in the USA (1924), where he immediately applied for, and was granted Citizenship of the United States as late as 1930.
Due to US citizenship requirements he had to return to Austria, where he finished his medical studies 1926 and was graduated as Dr. med.
He had a quite interesting career as physician between 1930 und 1933, based on the Pacific Institute for Tropical Medicine San Francisco,[2] including a research visit in South America (1930–1931), work as ship's doctor (1931–1932) and research in Papua New Guinea (1932–1933).
There he started his Nazi connections, by pretending to be a member of the Spanish Republicans, but transferring all informations obtained there to the German Gestapo.
