Adolf Abraham and his brother Julius worked towards the end of the 19th century in the Bonn branch of Leonhard Tietz's department store group, which was also Jewish. In 1901, the brothers left this branch and opened their own department store in rented premises at Hauptstraße 59 in Rheydt.

Jonas Benjamin Jonas founded together with his brother Abraham Jonas on 1.11.1869 the leather shop "A. & J.B. Jonas", which moved into its business premises at Lüpertzender Straße 71. In January 1878 Abraham Jonas left the joint enterprise, but the business name did not change. A short time later, a shank factory was added to the leather shop. Although the business continued into the 20th century, Jonas Benjamin Jonas retired from the business at an early age and devoted himself to honorary functions.

In 1869, Salomon Bellerstein, who was just 21 years old at the time, founded his own manufactory goods shop. He moved into his business premises at the former Krefelder Straße 51, which meant that he was in the direct vicinity of Jonas Lennhoff's store, thus competing with him. The Bellerstein fashion house quickly became one of the largest of its kind in Gladbach. In 1888, 20 Jewish employees were employed here in addition to Christian ones. It is possible that Bellerstein's economic success was one reason for Josef Lennhoff's closing down the business.

In 1868, Josef Lennhoff, who had come to Gladbach only a year earlier, founded the "Manufaktur- und Modewarenhandlung Lennhoff". Lennhoff moved into his business premises at the former Krefelder Straße 47, today's Hindenburgstraße.

Josef Lennhoff advertised a lot in the Gladbach daily newspaper. Among them also reports that he had his store closed on (high) Jewish holidays. However, this does not seem to have harmed his business economically.

Already in 1856, Jacob Rothschild opened the " First Weinheimer Kleidermagazin " in Weinheim on Steinweg ( today's Hauptstraße).

The house Rektoratstraße 10 was acquired by the Jewish community in 1862. The building served different purposes. In the basement was the Jewish school. The private school was nationalized in 1905. It existed until 1932, when the last Jewish teacher - Israel Nussbaum - retired.

On the second floor of the building, the Jewish community built a prayer hall, which existed until the expropriation of the property around 1939/1940. The building passed into municipal ownership.

In the center of Süchteln, on Hochstraße, the brothers Nathan and Jacob Lifges had their "textile store N.Lifges". The store rooms were on the lower floor, the family lived in the upper.

By 1900, the Lifges brothers had abandoned their butcher shop and moved into the textile trade. In this field they proved to be very successful economically. After the death of Nathan Lifges in 1902, Jacob Lifges took over the business alone.

Aron Elkan founded a cardboard factory in 1861, the "Papier-u. Pappenf. A. Elkan". This must be imagined at first still very small and modest. The company premises were located on Krefelder Straße 175.

From 1896, Aron Elkan's sons Johannes and Peter, who had taken over the company in the meantime, began producing roofing felt. Roofing felt was a new product at that time, which was well received and promised good economic prospects with a rapid expansion of ever new factory facilities. The contested path brought great economic success already a few years.

In 1768, a Jewish cemetery on Venloerstraße in Dülken was mentioned for the first time. Until the year 1873 burials took place here. In the same year, the newer Jewish cemetery was then opened on Kampweg.

In 1938, the cemetery site was sold to a company. Today, the site, which is designed as a green space, is owned by the city.

In 1749 the Jewish cemetery was established on the Heidweg. It replaced an older cemetery, which can no longer be located today. Originally, the cemetery grounds were surrounded by a rampart. However, this was destroyed during a cemetery desecration in 1769.

The last burial took place here in 1931. There were also several desecrations of the burial ground during the National Socialist rule.
