Force and was influential in restoring German-Jewish relations and rebuilding Germany's economic ties after the Second World War through his international business associations. Eric's son, also called Max, is currently a partner in M.M. Warburg & Co. in Hamburg. Venetian origins The Warburg family is thought to have originated from Venice, at which point they bore the surname del-Banco. The historical documents describe Anselmo del Banco as Jewish and as having been one of the wealthiest residents of Venice in the early 16th century. In 1513, del Banco was granted a charter by the Venetian government permitting the lending of money with interest. Del Banco left with his family after new restrictions were placed upon the Jewish community coinciding with the establishment of the Venetian Ghetto. The family settled in Bologna, and from there to the German town of Warburg, and adopted that town's name as their own surname, after having moved to Hamburg after the Thirty Years' War.
