On 16 July 2020 Gunter Demnig laid four stumbling stones for Justin Herzfelder, Justin’s wife Erna, their son Heinz and Justin’s mother Henriette. Both parents and child were able to emigrate to the USA but the grandmother was deported and murdered. The laying of the stones was sponsored by Nathalie Frank, whose ancestors lived in the same house as the Herzfelders and were friends of the family.

Henriette Wertheimer was born on 11 January 1877 in Heidelberg. On 22 July 1896 she married the banker Leopold Herzfelder in Munich. Leopold was born on 25 May 1866 in Ermreuth in the administrative district of Forchheim. The couple had two children: Justin (born 21 May 1897) and Lilly (born 13 June 1904). The family moved to Nuremberg in July 1906.

On 8 May 1922 Justin married Erna Einstein (div. Vogel). Erna was born in Nuremberg on 18 March 1899, the daughter of trader Max Einstein and his wife Thekla (née Pollak). Her son Heinz was born on 14 May 1923.

Leopold Herzfelder died on 18 September 1929 in Nuremberg. His widow went to live for a time in Mannhein and Bad Homburg, before returning to Nuremberg in 1939.

Justin, together with his wife and son, emigrated to New York in April 1937. Henriette Herzfelder was deported to the Izbica ghetto on 24 March 1942 and murdered.
