Harry Dexter White was a senior U.S. Treasury department official. 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 imposed his vision of post-war financial institutions over the objections of John Maynard Keynes, the British representative. At Bretton Woods, White was a major architect of the International Monetary Fund and World Bank.
White was accused in 1948 of spying for the Soviet Union, which he adamantly denied. Although he was never a Communist party member, his status as a Soviet informant was confirmed by declassified FBI documents related to the interception and decoding of Soviet communications, known as the Venona Project.
