Jewish inmates of institutions were doubly stigmatised during the National Socialist era: as citizens of Jewish origin and as mentally ill patients.

As psychiatric patients, they were affected by the National Socialist health laws. They were threatened with forced sterilisation and limited food and treatment. As Jews, they were subject to the Nazi race laws. They were deprived of their traditional rights in the health care system.

From 1939 onwards, there is proof that 235 Jewish patients were admitted to the Wittenau Sanatoriums. This shows that a relatively large number of Jewish patients were admitted here compared to other institutions. By the end of 1942, all the Jewish patients who did not die in Wittenau had been removed from the institution. They were either victims of the general deportations of Jews or killed in ways especially designed for Jewish patients.
