Klara Boroschowitz was born in Munich on February 19, 1878. Her parents were the businessman Jakob Boroschowitz and his wife Lina. Klara married Theodor Grüner, a Catholic. Their twin sons, Emil and Fritz, were born on October 22, 1908. In 1935 Klara and Theodor Grüner moved to Rosenheimer Strasse 216.
The Nazi accession to power brought about radical changes in the life of Klara Grüner. Her marriage was now considered “mixed.” She was somewhat protected from anti-Semitic persecution by the fact that she was married to a non-Jew. After her husband’s death on August 24, 1941, however, she was subject to the entire range of National Socialist anti-Jewish measures.
In November 1941, Klara Grüner was compelled to leave her apartment and move to Theresienstrasse 23. Later the Gestapo made her move to the “Judenhaus” (“Jews’ house”) at Lindwurmstrasse 125.
Klara Grüner had to perform forced labor from 1942 to April 1943. On April 21, 1943 the Gestapo deported her to the Theresienstadt ghetto. On May 15, 1944 she was on SS transport no. Dz/711 from there to the Auschwitz extermination camp. She arrived in Auschwitz on May 19, 1944 along with 2,500 other Jewish women, men and children. The SS crowded them all into the so-called Theresienstadt family camp in the BIIb section of Auschwitz Birkenau. Like all the other inmates, she will certainly have had to perform forced labor under harrowing conditions. The circumstances of Klara Grüner’s death are unknown. If she survived until July, she will have been murdered in the gas chambers with the other women, men and children of the “Theresienstadt family camp” on July 11 and 12, 1944.
