About the study

The Hermann Tietz family group was one of the pioneers of the German department store industry at the beginning of the 20th century. After the National Socialist takeover, the Jewish owner family was forced out of the company by a banking consortium and Hermann Tietz became Hertie. For a long time, the troubled past of this major department store brand of the West German economic miracle lay in the dark. In their study, Johannes Bähr and Ingo Köhler shed light on the anti-Semitic agitation against the owners of the Hermann Tietz Group, the Tietz/Zwillenberg family, the "Aryanization" of their company assets and the fate of both families after their ousting from the company. They also investigated the development of the Hertie Group up to the disputes over restitution and compensation in the immediate post-war years. Drawing on a wide range of sources, including previously inaccessible documents, a detailed picture emerges of a department store history caught between persecution, loss and responsibility.

GUG was commissioned to carry out this study in 2020 by the non-profit Hertie Foundation, which was also co-financed and supported by the Karg'sche Familienstiftung. From the outset, the Nazi experts Bähr and Köhler had complete academic freedom and independence in their study.

The study will be available in bookstores from December 6, 2023.

Sabine Falke, Vorsitzende des GUG e.V., betont bei ihrer Begrüßung, warum die Aufarbeitung von NS-Geschichte für die Gegenwart und Zukunft so bedeutsam ist. Dr. h. c. Frank-J. Weise wiederum, Vorsitzender des Vorstands der Gemeinnützigen Hertie-Stiftung, stellt in seinem Grußwort heraus, dass die Stiftung die Erinnerung an Hermann Tietz, den Warenhauskonzern, die Familie und deren Schicksal auch in Zukunft wachhalten wird.

Autor Prof. Dr. Ingo Köhler erläutert die Studienergebnisse zum Schicksal der jüdischen Inhaberfamilie Tietz/Zwillenberg nach ihrer Verdrängung aus dem Unternehmen und den Restitutionsprozess nach 1945.

Autor Prof. Dr. Johannes Bähr spricht über die große Bedeutung des Warenhauskonzerns Hermann Tietz, die nationalsozialistische Hetze, die „Arisierung“ des Familienkonzerns und die Übernahme des Unternehmens durch Georg Karg.

Moderator Carsten Knop, Herausgeber der FAZ, diskutiert mit den Autoren und Dr. Orna von Fürstenberg, Gemeinderat der Jüdischen Gemeinde Frankfurt, über die Leistung von Hermann Tietz beim Aufbau der Marke „Hertie“, über die Unmöglichkeit einer „Wiedergutmachung“ und welche Lehren man dennoch aus der Aufarbeitung ziehen und in konkretes Handeln für Gegenwart und Zukunft umsetzen kann.

Historical conference on November 8, 2023, Maritimes Hotel Hamburg
Cooperation event of Wintershall Dea AG and the GUG e.V. Topic: DEA under National Socialism

Wintershall Dea and GUG hosted a historical conference in Hamburg to present the interim results of a study on Deutsche Erdöl Aktiengesellschaft (DEA). However, the presentations were not limited to DEA alone, but also dealt with the German oil industry in general.

ANDREA SCHNEIDER-BRAUNBERGER (GUG) and MICHAEL SASSE (Wintershall Dea AG) introduced the event. Taking a micro-perspective approach, MANFRED GRIEGER first spoke about the DEA site in Rositz and emphasized that it owed its creation, growth and development primarily to armaments. RAINER KARLSCH reported on DEA's most important production area, the "Ostmark" (Austria), providing information on the conspiratorial Nazi oil strategy before and after the "Anschluss" and the significance of the Austrian oil fields for DEA's development from a coal to an oil-producing company. KARSTEN LINNE then dealt with the German oil industry and the Nazi economic system using the Kontinental Öl-AG (Konti Öl) as an example, through which an attempt was made to establish a German global corporation in the global oil sector. The last lecture was a joint presentation by CHRISTIAN HELLWIG, RITA SEIDEL and JANA STOKLASA on the oldest oil production area in Celle. The focus here was on topics such as the Nazi connection of workforces, the use of forced labor and research and teaching on mineral oil at the Hanover University of Applied Sciences and Arts.

The conference was rounded off by a panel discussion chaired by INGO KÖHLER. Grieger, Hellwig, Sasse and Schneider-Braunberger discussed the history of Wintershall Dea, what lessons can be learned from the history of the oil industry under National Socialism, as well as technical questions about the context of the oil industry in the Nazi system.

You will find a detailed conference report here shortly.
