経済協力局
President Harry S. Truman nominated Hoffman to lead the Economic Cooperation Administration (ECA) in April 1948. Truman initially wanted to nominate Dean Acheson, but Hoffman was a more acceptable candidate to Congress, which preferred someone with more business acumen. In this role as administrator, he was responsible for managing the distribution of U.S. aid to post-WWII Europe. He primarily worked with the Organization of European Economic Cooperation (OEEC) and coordinated policy with the U.S. State Department.
