Warburg family

The Warburg family is a prominent American banking family of German 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.

They originated as the Venetian Jewish del Banco family, one of the wealthiest Venetian families in the early 16th century. Following restrictions imposed on banking and the Jewish community, they fled to Bologna, and thence to Warburg, in Germany, in the 16th century, after which they took their name.

The family re-established itself in Altona, near Hamburg in the 17th century, and it was there 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: M.M.Warburg & Co., Warburg Pincus, S. G. Warburg & Co. (becoming UBS Warburg).

The family is traditionally divided into two prominent lines, the Alsterufer Warburgs and the Mittelweg Warburgs. The Alsterufer Warburgs descended from Siegmund Warburg (1835–1889) and the Mittelweg Warburgs descended from his brother Moritz M. Warburg (1838–1910). They took their nicknames from the brothers' respective addresses in Hamburg's Rotherbaum neighborhood. The brothers were grandsons of Moses Marcus Warburg.
