THE SIEMENS-HALSKE-SCHUKERT COMBINE. Before the Second World War this German electrical engineering firm had technical specialists working in Britain many of whom had access to British armaments factories and service establishments in the course of their business. MI5 was conscious that from 1936 onwards the Nazi regime had made it clear that service to the Fatherland was obligatory on the part of Germans living and working abroad. This service was deemed likely to include acts of espionage. Evidence of spying on the part of Siemens employees emerged during both world wars. Much of the file relates to the hostile activities of Siemens overseas employees during the Second World War
