Structure of the Gestapo Staatspolizeirektion Duesseldorf: Division II (Domestic Police) is subdivided into subdivisions, of which the Department of Culture (II B), Division II C (Reaction and Opposition), II H (Party Affairs) and II E, the Department of Economics, are mentioned. Head of the Cultural Department (II B) was from 1935 to 1943/44 police superintendent Wilhelm Friedrich. The cultural department was again subdivided into the department for the Catholic Church (II B 1), the department for the Protestant Church and sects (II B 2), the department for emigrants (II B 3) and the department for "Jewish Affairs" (II B 4), which was founded in the fall of 1935 after the proclamation of the Nuernberg race laws. The head of the Cultural Department and the Department for "Jewish Affairs" were administrative officers, not detective superintendents, as usual with department and unit heads.. The Department for Emigrants (II B 3) and the Department for "Jewish Affairs" (II B 4) had the same staff and the same head. Until 1940 it was police(chief)inspector Viktor Humpert, who had at least one executive officer assigned. From 1938/39, two executives worked in the Department for Emigration and "Jewish affairs": Alfred H. and Georg Puetz. From 1941 to 1943, they had the conscripted Waffen-SS man Fritz Gestermann as assistant. Furthermore, the two administrative clerks Hermann Waldbillig and Edmund Ommer were active in these departments, as was the police employee Heinz Illig. Humpert's successor was Becker. Before 1939, the Jewish section was staffed only by Humpert, Alfred H. and one or two other employees, and from 1942/43 onwards, after the deportations were completed, the staff of the unit was reduced to this level again. The Stapo-Stelle Duesseldorf had several branches (Duisburg, Essen, Krefeld, Moenchengladbach, Oberhausen, Wuppertal), to which other branches were subjected. The heads of the branches Solingen and Muehlheim an der Ruhr are mentioned: Josef Koke and Karl Kolk. The branch offices did not have their own Jewish Affairs Departments, since their cultural departments (II B) were not subdivided. Management of "Jewish matters" was taken over by the department head or the longest-serving officer. The Jewish section of the Gestapo in Duesseldorf cooperated with other state authorities and therefore was in charge of census and controlling of the the Jewish population, of tackling violations of anti-Jewish laws and later carrying out the deportations. The Gestapo got their information through informers and the occasional use of confidential informers in Jewish enterprises and the emigré community. It also went on patrol and executed (sometimes unannounced) house searches. In interrogations, psychological and physical extortion was used, but use of violence is only testified to during the war.
