The tanner Salomon Heymann from Essen-Steele moved to Dülmen in 1838 to the then Lohmühle. He acquired two plots of land at the corner of Brokweg and Borkenerstraße and built a residential and factory building on them. Around 1840 the tanning business was started. After the death of the founder Salomon Heymann in 1874, the business was passed on to his son Hermann (Chaim ) Heymann. At the turn of the century, there was an operational reorientation of the company. The handicraft business (leather factory) became a trading company with leather goods. Hermann Heymann died in 1910.

In 1890, Kallmann Höchster moved from Vogelsberg to Fürth and founded the "Öl- und Fettwarenfabrik K. Höchster" there. In the list of commercial enterprises with Jewish owners in Fürth in 1938, Kallmann Höchster and Gustav Höchster are listed as owners/proprietors of the oil and grease goods factory K. Höchster.

The origins of the pencil factory Leopold Illfelder & Söhne lie in 1856, when Daniel Berolzheimer and Leopold Illfelder already founded the pencil factory Berolzheimer & Illfelder. When Daniel Berolzheimer died in 1859, his son Heinrich Berolzheimer took over his share of the company. Together with Leopold Illfelder, a branch office (Berolzheimer, Illfelder & Co.  or B. Illfelder & Co.) was founded in New York in 1861, later "Illfelder Importing Co" or "Eagle Pencil Co.".
