Salomon Oppenheim, Jr. (19 June 1772 – 8 November 1828) was a German Jewish banker, and the founder of the Sal. Oppenheim private bank. He was born in Bonn, the scion of an illustrious family of "Court Jews" (German: Hofjuden) who had served as advisers and moneylenders to the Prince-Archbishops of Cologne in the Rhineland area for several generations. In 1789, at the age of 17, Oppenheim Jr. set up a small commissions and exchange house in Bonn, then the residence of Prince-Archbishop Maximilian Francis of Austria.
