At the address Zwartbroekstraat 18, there is a Stolperstein for Ludwig Marx, widower of Hannchen Rothschild. Ludwig Marx owned a striking building at Frankfurter Straße 18 in Heilbronn, where his thriving wholesale business in intestines, spices, and butcher supplies was located. However, in December 1938, he had to sell the property well below market value to the city as part of the Arisierung, which displaced Jews from trade and housing. In September 1939, the couple fled Nazi Germany and settled in Roermond. Hannchen Rothschild died on May 29, 1941, and was buried in the Jewish section of the Oude Kerkhof in Roermond, near the Kapel in 't Zand.
