Harry Lloyd Hopkins
(August 17, 1890 – January 29, 1946) was an American social worker, the 8th Secretary of Commerce, and one of President Franklin Delano Roosevelt's closest advisors. He was one of the architects of the New Deal, especially the relief programs of the Works Progress Administration (WPA), which he directed and built into the largest employer in the country. In World War II, he was Roosevelt's chief diplomatic adviser and troubleshooter.
Hopkins served as an important foreign policy adviser and diplomat during World War II. He was a key policy maker in the Lend-Lease program that sent $50 billion in aid to the Allies; Winston Churchill in his memoirs devotes a veritable panegyric to this "natural leader of men" who had "a flaming soul".Harry Hopkins in Wikipedia
