From 1932 until its concession was withdrawn in 1939, Regina Mendelsohn, née Berg was the manageress of the Israelite Children’s Sanatorium in Bad Kissingen. She was born in Posen/ Poznán on November 11, 1888 as the fourth child of the merchant Isaak Berg and his wife Sara, née Blond. She had six siblings but two of them already died when they were toddlers. Her father died when she was ten years old.

In May 1932, Regina Berg moved to Bad Kissingen and took on the management of the Israelite Children’s Sanatorium in Salinenstrasse. According to her registration card, she was unmarried at that time, married a certain “Herr Metzger” in one of the following years but was divorced from him in September 1937 according to the registration card. As a consequence, she resumed her maiden name Berg again. The children’s sanatorium didn’t get a renewed concession for the spa season of 1938. Regina Berg went to Berlin without checking out in 1938 and went back to Bad Kissingen in Spring 1939 for two months. Then she finally checked out for Berlin in June 1939.

There she married Bruno Mendelsohn from Königsberg (now Kaliningrad) in Eastern Prussia who had a commercial agency in Berlin. They lived in Hektorstrasse 12 until they were deported. In March 1943, they were deported to Theresienstadt with the so-called “4. großer Alterstransport” (4^th great transport of the aged) together with about 1200 Jewish citizens. In the autumn, the two of them were deported to Auschwitz/ Oświęcim Concentration Camp and murdered there. 

Regina’s brother Simon also became a victim of Nazi terror; he was murdered in Sachsenhausen Concentration Camp in May 1942.
