Dr. Leo Heidenheimer was born on May 3, 1886 in Nuremberg, the son of a merchant. He studied in Munich, Geneva, Berlin and Erlangen. He successfully completed his law studies in Erlangen in 1911 with the award of a Dr. jur. In 1912, he was admitted to the bar at the Higher Regional Court and District Court of Nürnberg-Fürth. Leo Heidenheimer was a decorated and wounded front-line officer, but this did not prevent him from being expelled from the Nürnberg Bar Association in 1938 or from being sent to Dachau concentration camp from November 12, 1938 to December 21, 1938.

Jewish settlements have been established in Seelow since the first half of the 18th century: the Schutzjude Wolff Levin is mentioned in 1737. In 1901, there were 20 Jewish people living in the town; a Jewish community was formed in 1830. Around 1800, Jewish families in the town bought a piece of land at the end of Hinterstrasse in order to establish a cemetery here. By 1876, 80 burials had taken place in the cemetery.
By 1910, there were only six Jewish inhabitants left in Seelow.

The Jewish cemetery in Wusterhausen/Dosse, located directly on Klempowsee, was completely destroyed and made unrecognizable by overbuilding [GPS: 52.900425, 12.459218]. However, the cadastral documents show that the plot formed an approximate rectangle with an east-west orientation.

The site was probably enclosed by a fence or wall. However, the direction and arrangement of the gravestones is just as unknown as their number and the number of burials carried out.

The recovered fragments are made of sandstone and limestone, a common material for gravestones at the time.

A Jewish community was only founded very late in Wittenberge, but a Jewish cemetery had already existed there for a long time. A section of the Christian town cemetery on Perleberger Strasse was demarcated on the northern edge, which served as a special burial ground for Jewish burials.

The address book of the city of Frankfurt am Main from 1922 contains the following entries: Dr. M. Albersheim, founded in 1892, factory of fine perfumes and cosmetic products, Lützowstr. 15-17, (Tel. Hansa 561 and Hansa 1689 shipping department)  Owner: Walter Carsch and Fritz Albersheim. - Dr. M. Albersheim, specialty store for fine toilet articles, store Kaiser-Str.9. Erdg. (Hansa 2561) - Moritz (Moises) Albersheim was born on June 18, 1854 in Nottuln, district of Coesfeld in North Rhine-Westphalia.

The community in Wandsbek, which had existed since the 17th century, buried its dead in the old K nigsreihe cemetery. After this was completely full, a new site was purchased in Jenfelder Stra e e (formerly Jenfelder Weg) and a cemetery was established there, initially for 388 graves. It was opened in the summer of 1877. In the same year, a mortuary, a Kohanim hall and an apartment for the cemetery caretaker were also built. The total area would have allowed an expansion to 1000 plots. Between 1887 and 1942, 143 bodies were buried in the cemetery.

The company " Gebr. Goldschmidt "  (the owners Salomon and Josef Goldschmidt imported domestic and foreign textiles from factory production and exported domestic canvas on a large scale)  was divided in 1841. In 1851 Samuel Frank took over the trading business of Salomon Goldschmidt. Towards the end of the 19th century, the Frank brothers' textile company employed numerous homeworkers in Rahden. This later became the textile company " Daniel Oppenheim & Sohn " on Rahdener Kirchplatz. - Daniel Oppenheim and his wife were very active in the Jewish community.
