When the Nazis
came to power in Germany in 1933, the Tietz were persecuted because of their Jewish heritage. The store was boycotted. All businesses of the Tietz family were "Aryanized" (i.e., seized from Jews and transferred to non-Jewish owners) and the family members emigrated. The Tietz department store was "aryanised" in 1934.
Oscar Tietz's son Martin Tietz migrated with his wife to Liechtenstein in 1939 and his assets were seized by the Gestapo.[3] In 1933,
Georg Karg, the new non-Jewish owner, changed the company's name to "Hertie Department Stores" as an abbreviation of Hermann Tietz. Oscar Tietz's son-in-law,
Hugo Zwillenberg was arrested by the Gestapo in 1938 and imprisoned in
Sachsenhausen concentration camp for three weeks, after which he emigrated to the Netherlands. == Postwar ==
