On 11 June 2021, on the initiative of Daniela Epstein from Jerusalem, Gunter Demnig laid eleven stumbling stones for her ancestors in Nuremberg. Markus Weih from Nuremberg sponsored the stones laid for Emil and Lina Heidenheimer. The Heidenheimers were murdered in the Izbica ghetto.

Emil Heidenheimer was born on 10 September 1877 in Stuttgart, the son of Samuel Heidenheimer and Auguste (née Grünwald). In July 1909 he moved to Nuremberg, where he married Lina Heimann on 29 July. Lina was born on 7 January 1881 in Kitzingen. Her parents were Samuel Heimann and Emilie (née Ullmann). The Heidenheimers had no children. In Nuremberg Emil worked as a trader.

On 24 March 1942 Emil und Lina were deported to the Izbica ghetto and murdered.
