Kaethe is known from her Gleiwitz residence card, which shows that following her arrival in Gleiwitz from Breslau in October 1928 she lived with Fritz Wiener. Her married state and surname suggest they were husband and wife. Her arrival in Gleiwitz from Breslau was registered two days after Fritz's mother made the same move. That Kaethe was Felix's wife is confirmed by his siter-in-law in a Yad Vashem Testimonial.



Felix and Kaethe were deported from Breslau to Auschwitz concentration camp on 04/03/1943.
