David and Friederike Adler lived at Oesterholzstrasse 80 at least since 1918, with interruptions. David Adler was a businessman and trader.

Following the “Pogrom night”, David was taken into so-called “preventive custody” at the Steinwache police station from 12 – 17 November 1938. The couple were later deported on 29 July 1942 to Theresienstadt and from there, on 15 May 1944, to Auschwitz, where they were presumably immediately murdered.
