Hamburger & Littauer was a store run by Jewish merchants Simon Hamburger and Nathan Littauer in Brunswick. The ready-made clothing store was founded in 1888 and was located in the house at Kohlmarkt 3-4 in the city center. The fashion store was very successful until the Second World War and Jewish boycott of Jewish stores during the Nazi regime. From May 1, 1933, the company was Aryanized and bore the name "Rosbach & Risse". The owners of the Hamburger & Littauer company were Paula Rosbach and Siegfried Fröhlich.

The Israelite community of Neukalen was able to build a synagogue in Wasserstraße in 1843, thanks to a donation from descendants of Neukalen Jews. Next to the synagogue, the tabernacle for widows was built at the same time. In 1899 both houses were sold due to their poor condition. The Stiftshaus was preserved, but was no longer used by the local Jewish community, which had already dissolved in 1900. The tabernacle house for widows was renovated in 2009.

The new Jewish cemetery was established in 1917/18 as the present part of the main municipal cemetery. The first person buried in the cemetery was Berta Hammerschmidt, who died in early November 1916. After the old Jewish cemetery was fully occupied in 1916 and a new one was still in the planning stage, the Chief Rabbi of Cottbus, Dr. Posner, had contacted Mayor Dreifert after her death on behalf of Judicial Councilor Abraham Hammerschmidt.

On the left side of the street was the fur store of the Lehmann family. In the course of the city redevelopment in 1978, this house was also demolished. Two brothers of the Lehmann family were practicing Christians. The entire Willi Lehmann family was transported to the ghetto in Warsaw. The brother, Eugen Lehmann, organized contact with the family and food deliveries from Bernau. With his support, Willi and his wife were able to work outside the ghetto in a fur factory. They managed to escape from the ghetto shortly before the uprising.
