James Paul Warburg (August 18, 1896 – June 3, 1969) was a German-born American banker [Ethnicity: Jewish]. He was well known for being the financial adviser to Franklin D. Roosevelt. His father was banker Paul Warburg, member of the Warburg family and “father” of the Federal Reserve system. After World War II, Warburg helped organized the Society for the Prevention of World War III in support of the Morgenthau Plan [Post-Surrender Program for Germany].
Warburg was a member of the Council on Foreign Relations. He gained some notice in a February 17, 1950, appearance before the U.S. Senate Committee on Foreign Relations in which he said, “We shall have world government, whether or not we like it. The question is only whether world government will be achieved by consent or by conquest.” (source)
