The “Private Waldschule Kaliski” was founded in 1932 by the Jewish teacher Lotte Kaliski, after she came to Berlin a year earlier and found no employment, partly because of her physical disability. The school was first opened in Eichkamp. Until 1934, Jewish and non-Jewish children were taught there under reformist educational approaches. From Easter 1934, all non-Jewish children and teachers had to leave the school. In 1936 the school was relocated to Dahlem, Im Dol 2-6, to a villa whose residents had previously emigrated from Germany to Austria.

In 1865, a Jewish cemetery was established at the edge of the general cemetery, until then, the Jewish cemetery in the neighboring Tangermünde had been used.

The Jewish cemetery is located within the cemetery at the Uengelinger gate, in its northern area. From the gate opposite house 2 of the University of Magdeburg-Stendal at the Osterburger Straße one follows the path straight ahead until shortly before the opposite cemetery wall, then turns left and has in front of him the enclosure of the Jewish cemetery, a half-high open brick wall. It includes about 50 gravestones.

In Bernburg there were three Jewish banking businesses: Bankhaus Gumpel & Samson in Friedensallee (formerly Kaiserallee), Bankhaus Wolff in Breite Stra&szlig and Bankhaus Levi Calm & Söhne in Nienburger Stra&szlig. The latter was founded by Levi Galm, who had been running a wool trade in Waldau since 1785. The bank operated several plants in Bernburg, including a valve factory, a joint-stock brewery and a lottery business. The bank played a central role in the electrification of the town.

The Berlin address book 1916 contains the following entry: Sobernheim Curt, Director at Commerz. - und Disconto Bank, W50 -  Augsburger Straße 2nd - 3rd   Erdg. Cp. - T. Lzw. 4730.

As late as August 1840, the Chief Rabbi Dr. Ullmann had submitted an application for the establishment of a Jewish elementary school - a predecessor of today's elementary schools. This application was supported by Mayor Leysner of the city of Krefeld. A school building was erected towards the end of the same year. The school rooms were located at Lohstraße 613. From 1853, the Jewish school moved to premises at Petersstraße 159 (today house number 41) due to lack of space. In 1860, the Jewish community acquired the house at Felbelstraße 15 (later 26) to accommodate its growing student body.

A Jewish cemetery appears in the sources for the first time in 1751. It was located on the crossroads. Since the burial ground was already completely occupied in 1778, the Linner magistrate left the adjacent field piece to the Jewish community.

The Jewish cemetery in Krefeld Uerdingen was established before 1844. The former burial ground was located in the triangle between Duisburger Straße and the old Friedhofsstraße. Burials were held here until 1942, the same year the Jewish community was forced to sell the site under National Socialist pressure. IG Farben (Bayer AG) acquired the property. The cemetery was leveled and built over. No graves or gravestones remain. On site, there is no evidence of the former burial ground.

On 6.12.1964 the Jewish community inaugurated a prayer hall on the corner of Rheinstrasse and Philadelphiastrasse, which provided space for about 130 people. Due to the growth of the Jewish community, the space quickly became too small. Since 1978, the Jewish community had rented rooms on the second floor of the house Wiedstraße 17 for conversion into a prayer hall. This prayer hall could be referred 1981.

Shortly after the end of the war in 1945, Jewish life in Krefeld revived. About ten Jews joined together to form a (new) Jewish community. The silk manufacturer Fritz Leven became the head of the community. The community initially met in his private house at Bismarckstrasse 118. 116 and 118 belonged to the Jewish community of Krefeld. The community grew again. At the end of the 1960s it had about 120 people. This number remained fairly constant for the following decades.

From 1848, Fischeln's small Jewish community set up its own prayer room at Marienstraße 37. To hold a service, however, the room could be used only years later, because previously the number of minyan (10 Jewish males are required for a service, otherwise it can not be held) had not been reached.

Around 1910, at the latest by the beginning of the First World War in 1914, the prayer room was no longer used.
