James Warburg

James Paul Warburg (1896-1969) was a German-born American banker who chaired the International Acceptance Bank and served as a financial adviser to President Franklin D. Roosevelt during the early New Deal, including at the 1933 London Economic Conference. He later became a prolific author on foreign affairs. He belonged to the German-Jewish Warburg banking family; his father, Paul Warburg, was a principal architect of the Federal Reserve System, and his mother, Nina Loeb, came from the Kuhn, Loeb & Co. family. Both parents were documented as Jewish.
