On 11 June 2021 Gunter Demnig, following a suggestion by Daniela Epstein from Jerusalem, laid eleven stumbling stones in Nuremberg for her descendants. Matthias Unterdörfer and Sabine Scherer from Nuremberg sponsored the laying of stumbling stones for Gustav and Clara Diebach, and for their two children Liselotte and Gerda. The Diebach family was murdered in the Izbica ghetto.

Gustav Diebach was born on 4 May 1893 in Wenings near Büdingen in the Wetterau. His parents were the trader Gabriel Diebach and his wife Mina (née Stumpf). In 1911 the family moved to Nuremberg. Gustav worked here as a trader.

On 8 July 1927 he married Clara Meyerstein. Clara was born in Artern, at that time part of the Prussian province of Saxony. Her parents were Matthias Meyerstein and Flora (née Katzenstein). Gustav and Clara had two daughters: Liselotte (born 21 April 1928) and Gerda (born 1 December 1934).

Gustav, Clara, Liselotte and Gerda were deported to the Izbica ghetto on 24 March 1942 and murdered.
