Before serving as America’s 31st President from 1929 to 1933, Herbert Hoover had achieved international success as a mining engineer and worldwide gratitude as “The Great Humanitarian” who fed war-torn Europe during and after World War I. After the United States entered the war, President Wilson appointed Hoover head of the Food Administration. He succeeded in cutting consumption of foods needed overseas and avoided rationing at home, yet kept the Allies fed. In 1947 President Truman appointed Hoover to a commission, which elected him chairman, to reorganize the Executive Departments. He was appointed chairman of a similar commission by President Eisenhower in 1953. Many economies resulted from both commissions’ recommendations. Over the years, Hoover wrote many articles and books, one of which he was working on when he died at 90 in New York City on October 20, 1964. Get Involved.
