Alexander Lubranczyk lived with his wife and two children in Berlin, where he ran a tailor's workshop together with his brother Louis. After his wife died in 1928, he moved to Munich to live with his daughter Gertrud. She had been married to Siegmund Hirsch since 1914 and had two children. Since Alexander Lubranczyk had spent most of his life in Berlin, he probably found it difficult to understand the Munich dialect. His grandson later described him asvery quiet and distant.
His daughter was able to flee to Chile with her husband and daughter in 1939, and her son managed to emigrate to England. Due to his advanced age, it was difficult for Alexander Lubranczyk to obtain a visa to emigrate. He was forced by the Nazis to move to the Jewish retirement home on Mathildenstraße. In 1941, the Gestapo took him to the so-called ‘Judenlager Milbertshofen’. From there, the 88-year-old was deported to the Theresienstadt ghetto in the summer of 1942, where he was taken to the infirmary called ‘Siechenheim’. Conditions there were catastrophic. Alexander Lubranczyk died only a few weeks after his arrival.
