Rudolf Conitzer was born in 1851 in Jeschewo, a small village outside Schwetz. His father Moses Conitzer had a small department store there. Rudolf worked in this department store from the age of 13 and helped his father to expand the business for the next 14 years.

In 1878, Rudolf Conitzer founded his own company under the name Kaufhaus Rud. In 1911, it was the largest business in the area.

On June 21, 1692, the merchant Assur Marx (who lived from 1699 to 1730 in the building at Groäe Märkerstraße 14, which is still standing) was able to purchase a garden for the Jews living in Halle to create a cemetery. In the following years, foreign Jews who died at the Leipzig Trade Fair were also buried in this cemetery. In 1716, it was extended by the purchase of a neighboring plot of land. It was used until the new cemetery was built at the end of the 1860s. In 1937, the cemetery was destroyed by the National Socialists.
