Originally from Göttingen, Liebmann arrived in Berlin following his marriage to Esther, the widow of court Jew Israel Aaron of Konigsberg, whose position he inherited.

His first wife, who died young, was Malka, the daughter of Court Jew Samuel Hameln.

[2] His wealth and standing at the court enabled him to exercise great influence in the early period of the Jewish congregation.

He acquired the privilege of having his own synagogue, to which he appointed as rabbi his nephew and son-in-law, Aaron ben Benjamin Wolf.

Due to his differences with Marcus Magnus, court Jew of the crown prince, the congregation was split into two factions, and after his death the quarrel was continued by his widow and his sons Israel and Liebmann Jost.
