Anna opens her own hat store and workshop in Bonn, the "Modehaus Klaber". In 1929, the family moves into the apartment above the store. A year later, Anna buys this house. She is now a modern working woman: in addition to running the household with two children, she has her own business with a workshop and manages two tenants.

When the National Socialists came to power, life changed for every member of the family. Jews are gradually excluded from society as a result of racist legislation. On October 26, 1938, an immediate residence ban was imposed on Jews of "Polish origin" in the German Reich. Paul Getreider, whose place of birth is in Poland, which was re-established in 1918, is regarded as a Polish citizen. He was arrested at night in October 1938 without warning and deported to Poland. Anna stays behind in Bonn with Margot and Heinz. During the November pogrom, the three witness the brutal destruction of the hat store and workshop by SA men.

Due to their direct relationship to Paul, Anna and Heinz also had to leave Germany in April 1939. As the daughter of Moritz Holländer, Margot remains alone in Bonn and desperately searches for a way to leave. In mid-August, she receives permission to enter Great Britain to work there as a maid. In May 1940, she is able to leave for the USA.

Letters and photos from the part of Poland occupied by the Germans since September 1939 still reach Margot in the USA, but contact breaks off in 1942. Her mother Anna is murdered in Auschwitz, her brother Heinz dies in a German labor camp. Paul Getreider, who was visiting Lviv in September 1939, was arrested there by the Soviet secret police and sent to a labor camp near Moscow and later to one in Astrakhan. Here his trail is lost.

Margot lived in the USA until her death in 2004. She became an American citizen, married and started her own family. In later years, she visited her home town of Bonn to tell her story in schools.

The exhibition also shows the lives of other members of the Klaber family from Zülpich - Margot's grandparents, uncles and aunts, cousins - and those of friends. Almost all of them did not survive the Nazi era.
