The banking house is founded in 1870, the owner and banker Lißmann Fürth then takes over the banking house Maron & Cie (founded before 1867), which is located at Marktplatz 2. In 1878, an address book entry is listed under his own name (Fürth), Lißmann is the owner. Michael, as well as Moses Fürth are involved in the management, but also run a bristle store together. This, as well as the bank, is now located at Fahrgasse 14. Later, the banking business moves to Krämerstrasse 12.

Founded in 1890 by Marcus Bacharach, it is then located at Krämerstraße 8. In the 1920s, it is located at Römerstraße 9, "opposite Hotel Adler", an obviously renowned hotel. The business is unusual because Marcus Bacharach's wife Amalie née Herzberg has power of attorney. The bank must be abandoned due to the lack of a successor with the death of Marcus Bacharach.

The bank is founded in 1835 by Hirsch Benjamin and is addressed at the time in Hanauer Judengasse 78. In 1855, son Israel takes over and moves to Salzgasse 909. At the latest in 1867, his son Michael works with them and they move to Steinheimer Strasse 20. In 1876, Joseph Oppenheim takes over, in 1886 Karl Oppenheimer and later Hermann Oppenheim(er). Before 1917 they move to Römerstraße. In the same year, the company joins the Mitteldeutsche Creditbank. Hermann Oppenheim(er) manages the branch.

Founded in 1873, it is then the "5th bank house in hiesiger Stadt" and can be found at Paradeplatz 235 and belongs to the merchant Siegmund Marx. The bank is closed in 1883, presumably because of the lack of a successor.

The bank was founded in 1846, was then located at Salzgasse 850, later at Marktplatz 8, and belonged to Abraham Sonneberg and his son-in-law Max Hochstädter. The latter is described as always benevolent. Unusually, his wife, Anna Hochstädter, was granted procuration. When Max Hochstädters died in 1903, the bank had to be abandoned due to the lack of a successor.

The banking house is founded before 1837, can be found at that time at Paradeplatz 860 (today: Freiheitsplatz) and belongs to Nathan Sondheimer, son of an important rabbi. He pursues, similar to his father, only part-time, intensive studies of Judaism and is considered a benefactor in Hanau. With Nathan Sondheimer's death in 1862, the bank is probably abandoned. Son Moses Tobia is co-founder of a metal company in 1872.

The native of Hanau, Elisabeth Schmitz (* 1893, + 1977) was a Protestant theologian and resistance fighter against National Socialism. She graduated from the Schillerschule in Frankfurt in 1914. After studying history, German language and literature, and theology she was permanently employed at the Luisengymnasium in Berlin-Moabit as a Studienrätin.

In addition to this department store, Hanau could also boast the Wronker department store. This was founded by Hermann Wronker, a nephew of Leronard Tietz, who owned department stores in Mannheim, Nuremberg, Pforzheim, Darmstadt, Hanover, Worms and Frankfurt am Main. Both Hanau department stores and their Jewish owners fell victim to the crimes of the National Socialists.

In 1929, a department store of Leonhard Tietz AG was built at the corner of Nürnberger Straße / Hirschstraße (GPS1). Leonhard Tietz AG was founded in 1905 by the Jewish merchant Leonhard Tietz and owned several department stores. 

A new synagogue was built at 15 Main Street.
