Harry Dexter White (October 9, 1892 – August 16, 1948) was an American economist and senior U.S. Treasury department official. He was a primary participant in the Bretton Woods conference and the formation of the International Monetary Fund and the World Bank.
A number of sources from the FBI and Soviet archives, and messages decoded by the Venona project, suggest that he may have passed government documents to the the Soviet Union prior to World War II.
Harry Dexter White was born in Boston, Massachusetts, the seventh and youngest child of Jewish Lithuanian Catholic immigrants, Joseph Weit and Sarah Magilewski, who had settled in America in 1885. In 1917 he enlisted in the U.S. Army, and was commissioned as lieutenant and served in France in a non-combat capacity in World War I. He did not begin his university studies until age 30, first at Columbia University, then at Stanford, where he earned a first degree in economics. After completing a Ph.D. in economics at Harvard University at 38 years of age, White taught four years at Lawrence University in Appleton, Wisconsin. Harvard University Press published his Ph.D. thesis in 1933, as The French International Accounts, 1880–1913.
