In 1730, the Aldingen local lord Georg Wolf von Kaltenthal accepts the first two Schutzjuden (Abraham and Mazam Kahn) and assigns them the old parsonage near the Margarethenkirche as their home. In the attic of the parsonage, the two Jews set up a prayer room, which was probably used as a religious meeting place by the Jewish community of Aldingen until 1798 (purchase of the house at Kirchstraße 15 and conversion into a synagogue)

The Jewish community acquired a building site in 1825 and built a house with a mikveh (Jewish ritual bath) by 1826. In the purchase contract the community had secured itself: The contract could be canceled if no water was found "at a usable depth" within 30 days, which was apparently the case. In 1832 a stove was purchased to heat the water. On the second floor there was a baking oven, in which the Jewish community probably made matzos. In the building today, due to alterations, no traces of the mikvah can be traced.

Seligmann Isaak buys the house in 1798 against the resistance of the Aldingen community council and converts it into a house synagogue. By 1799, an extension is completed at the rear, housing the synagogue in the attic. In 1815, the house becomes the property of Veit Löwenthal, whose grandson David sells it in 1872. This ended its use as a synagogue. In 1859, the synagogue was temporarily closed by the Freudental rabbinate, as the Aldingen Jews boycotted the service in order to prevent the introduction of a Reform service with a prayer book in German.

In the Regensburg address book 1903 the following entry can be found: Leopold Loewenthal, grain and country products, fodder, seeds, fertilizers, corn import, St Georgenplatz 6. 

When a street name was sought in 2018 for the new street in the "Nördlich Brunnenstraße" development area in Remseck-Hochberg, the Remseck municipal council unanimously decided to name it after Abraham Herz. This was the first time that the Hochberg Jewish community was commemorated by a street name. Abraham Herz was a member of the Hochberg community council from 1845 to 1870 and thus, according to the description of the Oberamt Waiblingen from 1850, the first Jew in such an office in the Kingdom of Württemberg.
