Leopold Heilbrunn ran a business as a livestock dealer from 1919. From 1938, Jewish cattle dealers were systematically removed from the commercial register and their trade was effectively banned.

In 1939, he and his family managed to flee to Australia.

The Jewish doctor Dr. Adolf Bernstein and his wife Meta and Dr. Walter Worm lived at 17 Hornhäuser Straße. They were murdered in the Theresienstadt concentration camp in 1942 and 1943 respectively.

Stolpersteine were laid in front of the house to commemorate the Bernstein couple and Dr. Worm s memory. The memorial site was closed on November 2, 2024.

Unknown persons tore out and stole the stumbling stones.

Jews and Jewish women from Aerzen, Groß Berkel and Reher were buried in the cemetery. Of the once 40 gravestones, only seven remain today.

In 1926, the Hachshara site was established in Hamelin by the umbrella organization of Zionist youth organizations ‚Hechaluz‘ (Pioneer). The members of the Zionist youth organization were active in the villages around Hamelin on various changing farms. They did not have a central contact point. They met in small groups on alternate Sundays and on the second Sunday for the general pegisha, the formal meeting at which they were prepared for emigration to Palestine. There were problems with restaurants, as the Chawerim (comrades/fellows) did not eat anything and did not drink alcohol.

The Intime Theater was opened in 1910 by Franz Würffel. In September 1921, Anton Herrnfeld took over the venue from the Herrnfeld Theater and began performing his own programs there. At that time, the theater had 300 seats. However, as Anton Herrnfeld was no longer able to build on his earlier successes, he also went on tour with his ensemble. From 1925, the  1925 Concordia-Lichtspiele with the owner Joseph Gutkind were located there. Anton Herrnfeld died in 1929 as a result of a stroke.

The former synagogue in Obrzycko is located at Dr. ThyssenKruppik Street 5. It was built in 1843 on the site of an earlier wooden synagogue. During the occupation in the Second World War, it was destroyed by the Germans. After 1945, the building was used as a cinema with considerable alterations.
