On Sunday, 23 September 2018, several “Stones of the Disappeared” were placed in front of the house on Drobného Street no. 18, where the Tugendhat and Zinner family lived, in memory of the Holocaust victims. They commemorate Pavla Zinnerová, née Tugendhat, (Fritz Tugendhat’s aunt, his father Emil Tugendhat's sister) and her son Emil Zinner. Both were deported to Terezín (Theresienstadt) internation camp on 29 March 1942. Pavla Zinnerová, born on 8 April 1874, died on 6 July 1942 in Terezín. Her son, Emil Zinner, born on 23 August 1909, died on 8 July 1942 in Majdanek.
The placement of the memorial stones was initiated by Pavla Zinnerová's grandchildren, writer and screenwriter Markéta Zinnerová, Pavla Aviolat-Zinnerová and Alexej Zinner, who personally participated in this small ceremony together with Boris Barak Selinger from the Jewish Community of Brno.
In April 2017, a memorial stone was placed nearby for Marie Tugendhat, born Fleischerová, wife of Emil Tugendhat and mother of Fritz Tugendhat, who lived on Antonína Slavíka no. 9. Marie Tugendhat, born on 9 June 1869, was also deported to Terezín on 29 March 1942 and died in Treblinka.
