S. Bleichröder was a German family-controlled bank based in Berlin, founded in 1803 by Samuel Bleichröder. As an agent of the German Rothschild Bank, it was developed by Samuel's son Gerson von Bleichröder, who became known as "Bismarck's banker".
The firm declined in importance in the early 20th century and was eventually acquired in 1931 by Dresden-based Arnhold Brothers to form Arnhold and S. Bleichroeder.
