Moses Löw Rhau, born July 6, 1792 in Gunzenhausen, son of Löw and Schela Rhau, died May 27, 1868 in Gunzenhausen, married Hanna Epstein, daughter of local teacher Simon Jantof Epstein, in 1819. The couple had 14 children, some of whom emigrated to America. The family last lived in the property at Waagstraße 8, purchased in 1844, where Moses Löw Rhau ran a cookshop as well as trading in kosher goods. In addition, Moses Löw Rhau was, as far as is known, a shepherd and precentor from ca. 1851 - 1855.

In the building at Jägerstra&szlig 49/50, which still stands today, Bankhaus Mendelssohn & Co. had its headquarters from 1893 to 1938.

After their marriage in 1762, the famous enlightener and pioneer of the Haskalah, Moses Mendelssohn, and his wife Fromet Mendelssohn (née Guggenheim) moved into the house at the former Spandauer Straße 68 (corner of Karl-Liebknecht-Straße). Before them, other enlighteners such as M. Mendelssohn's friend Gotthold Ephraim Lessing had already lived there. Until his death in 1786, M. Mendelssohn, like many Berlin Jews, was not allowed to buy the house.
