In 1855, Daniel Rosenthal founded the company "Daniel Rosenthal & Co.". The previously existing company "Rosenthal, Steinhart & Co." was dissolved by mutual friendly agreement. Each of the 3 partners founded a new company. Daniel Rosenthal was so successful that he was called the "pioneer of the German corset industry". In 1874 the company became a partnership. Bernhard Rosenthal, Aron Fleischer with son Samuel Fleischer joined the company as partners.

The Blue House is a memorial and educational site for the history of the Jews on the Upper Rhine. Events and educational offerings at the authentic site recall the life of Jewish communities, the coexistence of Christians and Jews, as well as the violent end during the Nazi dictatorship in 1940 and establish contemporary references.

From the road "Sülzbach" leads over a (mostly open) barrier an initially asphalted path into the forest. After about 400 meters is then on the left hand the cemetery secured by a fence with its approximately 60 graves on the slope under high trees. The gravestones are mostly heavily weathered.

Underneath the Soviet military cemetery (already clearly signposted from Eisenacher Straße) lies the old Jewish cemetery with about 70 tombstones, some of which are still in good condition.
Left of the entrance to the military cemetery, a narrow path leads to the entrance of the Jewish cemetery.
Those wishing to visit the cemetery should inquire beforehand with the local congregation, which holds the key to the cemetery grounds. 
Both cemeteries, Jewish and Soviet, are well preserved and regularly maintained. 

The cemetery is located southwest of Seulberg, accessible via Landgrafenstraße, about 200 m after the last houses on the left side. 

The W. Michael Blumenthal Academy is located across the street from the Jewish Museum Berlin at Fromet-und-Moses-Mendelssohn-Platz in the former flower market hall of Kreuzberg.
