In the 1680s, Berend Lehmann (1661-1730) originally from the Prince-Bishopric of Essen, took up residence in Halberstadt. He had married Mirjam, the daughter of the deceased local Court Jew Alexander Joel. Starting in 1691, Lehmann was registered in the lists of Jews mentioned above as the owner of his own writ of protection. Today, he is considered to be one of the most important Court Jews of his day.From Halberstadt, which was after all no longer an independent sovereign entity, he established connections to the courts of Brandenburg-Prussia, Hanover, Brunswick and Saxony. Lehmann, as was typical of Court Jews, was also a promoter of Judaism. Thus, he supported both the local community and German-speaking Jewry beyond the local borders. Among other things, he financed and coordinated a new edition of the Talmud and thus created an essential basis for the training of rabbis.Berend Lehmann lived in the house at Bakenstraße 37, which he also had built, and for this purpose he relocated a brook that flowed across the street here. The vault on the house, which can be seen from the outside, is still a testimony to this time.
