Morgenthau was first appointed by the U.S. President Franklin D. Roosevelt as temporary President of the Bretton Woods Conference, which established the Bretton Woods system, the International Monetary Fund and the International Bank for Reconstruction and Development (the World Bank). During the inaugural plenary session on July 1, 1944, the Head of the Mexican Delegation, Eduardo Suarez, nominated him as Permanent President of the Conference. This motion was seconded by the Brazilian Head Delegate, Arthur de Souza Costa, and widely supported by several other delegations such as the Canadian and Soviet ones.
