Moses, Baruch and Max Reis together ran the woven goods wholesale and retail business Jakob D. Reis. Moses Reis was one of the co-founders of the Israelite religious community Adass Yeshurun, in which he also served as treasurer.

In 1869, the brothers Wolf and Heinrich Schwarzenberger opened the company Schwarzenberger and Sons in Karlsruhe. In 1871 Heinrich Schwarzenberger moved the company, which had been taken over by his father Levi Schwarzenberger in Untergimpern, - trade with cotton (fabric) remnants to Heilbronn. In later times Adolf and Lothar Schwarzenberger were the owners of the company. Heinrich Schwarzenberger died in Heilbronn in 1893. His grave is located in the Jewish cemetery in Heilbronn.

A legal dispute of the company "Gebr. Stern und Rosenstein" with the city of Heilbronn in 1840 about a large lot of stored wool in the wool house, which in the opinion of the company was not sufficiently secured, proves the increasing immigration and settlement of Jewish businesses in the city of Heilbronn. The owners of the company "Gebr. Stern und Rosenstein" were Isaac Stern, S. J. Stern and Moritz Rosenstein. Later they were joined by Maier Frankenbacher, who acquired citizenship in 1860.

Louis Steigerwald founded the Steigerwald liqueur factory in 1869. Later, the sons Siegfried, Julius and Oskar Steigerwald inherited the liqueur factory "Steigerwald AG". From 1936, the so-called "Aryanization" of the company took place. At the end of 1937, the Steigerwald brothers transferred their shares to a Heilbronn bank under pressure. From then on, the company bore the name "Lucca". After the loss of the company, the Steigerwald couple moved to Berlin with daughter Suse Steigerwald. The daughter Edith Steigerwald had already emigrated to England in 1937.

On July 29, 1862, Wolf Manasse Wolf, who was born in Bieringen an der Jagst, was issued a certificate by the city of Heilbronn to legitimize his announcement submitted to the city council in Heilbronn that he wanted to operate a rag and country products business on his own account. As early as 1864, Wolf Manasse Wolf purchased a plot of land at Paulinenstraße 21 and built a residential and commercial building on it. The business was very successful, so that in 1871 and 1876 two adjoining buildings were newly equipped for the business. In 1900, a warehouse was added to a fourth building.
