Martin Hallerz and Regina Riwka Malka Anker were both born in Tarnów, in what is now Poland. They married in Berlin-Charlottenburg in 1905. The couple moved to Munich, where Martin Hallerz ran a decorative painting business. Martin and Regina Hallerz had four children. From 1920 onwards, the family lived at Anglerstraße 9.
In September 1939, Martin Hallerz was arrested as a Polish citizen and deported to Buchenwald concentration camp. When he was classified as ‘no longer fit for work’ in March 1942, the SS deported him to the Bernburg killing centre as part of ‘Aktion 14f13’, where he was murdered. Regina Hallerz was forced to move into so-called ‘Jewish apartments’ in 1940. At the end of October 1941, she had to move into the barracks camp for Jews at Knorrstraße 148. From there, the Gestapo deported Regina Hallerz to Kaunas in November 1941, where she was murdered by SS men.
