Warburg family

The Warburg family is a prominent German and American banking family of German Jewish and originally Venetian Jewish descent, noted for their varied accomplishments in biochemistry, botany, political activism, economics, investment banking, law, physics, classical music, art history, pharmacology, physiology, finance, private equity and philanthropy.^[1]

They originated as the Venetian Jewish del Banco family, one of the wealthiest Venetian families in the early 16th century.^[2] Due to restrictions limiting Jewish involvement in banking, they moved to Bologna, and thence to Warburg, in Westphalia, in the 16th century, after which they later took their name. The first known ancestor was Simon von Kassel (1500–1566).^[3]

The family later established itself in Altona, near Hamburg in the 17th century, after the Thirty Years' War, and it was in Hamburg that M. M. Warburg & Co. was established in 1798, among the oldest still existing investment banks in the world. Other banks created by members of the family include Warburg Pincus and S. G. Warburg & Co., the latter having been acquired in 1995 by UBS.
