From 1890, the Jewish Community House also housed the Jewish Community School. This was crucial to the development of the community, as the Jewish Community School allowed for an autonomous, Jewish education for children.

For a long time there was vehement resistance from the Hanau Vorsteheramt against an independent, Jewish school system. Officially, the aim was to bring the Jewish community closer to the Christian community and to put aside mutual prejudices. At the same time, however, one reason was that the "Jewish youth should give up a number of bad habits".

The Jewish Community House housed in the annex the mikvah (ritual bath). 

The Jewish community house, built in the 18th century and acquired by the Jewish community after the opening of the Hanau ghetto, was located on the property, as well as the Jewish community school since 1890. The community house itself played a decisive role. The fact that the community house was acquired was an important stage in the development of the community. It was a step from isolation in the ghetto to becoming an emancipated part of the urban community. But a community house also strengthens a community in other ways.

Gustav Wetzlar was born in Hanau on July 3, 1799. He belonged to the first generation of Jews who benefited from the revolution of 1848/1849. He attended a grammar school in Frankfurt. Later he studied in Marburg, Göttingen and Vienna. From 1822 he was a doctor in Hanau and remained in Hanau until his death. He was also a member of the Judenschaftllichen Vorsteheramt in Hanau. In addition, he was a director of the Wetterauische Gesellschaft, which still exists today.

He was born on October 2, 1894. Otto was a well-known and popular Jewish doctor in Hanau. His practice was located at Hammerstraße 6. If someone was not in a financial position to pay for treatment, Otto Schwabe waived payment. He even made house calls, which was very unusual at that time, but was gratefully accepted. At Christmas he even gave presents to his poorer patients. It was more important to him to help people than to earn money. His family belonged to one of the older Jewish families of Hanau. The family name first appeared in 1689 under "Haus Zum Schwaben".

Isidor Berberich was born on June 19, 1893. He is also counted among the patriotic Jews. He fought for Germany in World War I and was killed near Bertrix on August 22, 1944. His parents had a cenotaph made for him at the family grave. In the former synagogue, which was unfortunately destroyed, hung a memorial plaque for the Jewish Hanau soldiers who died in the First World War. Isidor Berberich's name was also on this plaque. In Bertrix there is a memorial for the fallen French and German soldiers, among whom was Isidor.

In addition, members of the Oppenheim family were also buried there. Moritz Daniel Oppenheim, who was born but not buried in Hanau was very important for the Jewish community. The Oppenheim family was very well known in Hanau because of him. 

With the Enlightenment and the Revolution of 1848/1849, the Jews adapted more and more to society. At first there were gravestones inscribed with Hebrew from the front and Latin letters from the back. Eventually the old traditions were forgotten. Now the tombstones were inscribed only in Latin letters and the deceased wanted to write things, such as their professional position of which they were proud, on the tombstone, which was previously frowned upon and unthinkable. However, society also became more open to Jewish patriots.
