The Jewish brothers Jurek and Michał Rozenek grew up near Kraków. Their family was moved into the Łódź ghetto in 1940 and in August 1944 taken to Auschwitz-Birkenau extermination camp. Their relatives were murdered there; the brothers, however, were transferred to other camps to perform forced labor.
In early April 1945, all prisoners at Rehmsdorf, a sub-camp of Buchenwald concentration camp, were put on open freight cars bound for Theresienstadt. The Rozenek brothers managed to jump off the train in the Ore Mountains region. On April 16 they met Arno Bach from Niederschmiedeberg in a forest. Bach was opposed to the regime and felt sorry for the brothers, taking them to his home.
Bach and his wife Margarete hid the two men in a shed behind their house. The situation was particularly dangerous because Michał Rozenek was suffering from tuberculosis and coughing loudly. Arno Bach’s sister, who lived in the same house, her husband, and a further resident also helped the brothers. They were liberated by the Soviet army on May 8, and emigrated to Argentina in 1951.
During the 1980s Miguel (Michał) Rozenek visited his helpers in Niederschmiedeberg and in 1987 initiated their recognition as Righteous Among the Nations by the Israeli Holocaust memorial center Yad Vashem.
