Harry Dexter White (October 29, 1892 – August 16, 1948) was an American government official in the United States Department of the Treasury. Working closely with the secretary of the treasury Henry Morgenthau Jr., he helped set American financial policy toward the Allies of World War II. He was later accused of espionage by passing information to the Soviet Union.
He was a senior American official at the 1944 Bretton Woods Conference that established the postwar economic order. He dominated the conference, and his vision of post-war financial institutions mostly prevailed over those of John Maynard Keynes, the British representative who was the other main founder. Through Bretton Woods, White was a major architect of the International Monetary Fund and World Bank.
