Who was known as the "wartime food czar" during the Hoover administration?

Herbert Hoover is recognized as the "wartime food czar" during the administration prior to his presidency, specifically during World War I. In that role, he led the United States Food Administration, which was responsible for ensuring the nation's food supply, promoting food conservation, and managing agricultural production to support the war effort. Hoover's innovative approaches included campaigns encouraging the public to conserve food and grow their own produce, famously promoting "meatless Mondays" and "wheatless Wednesdays." This role significantly contributed to his reputation as an effective administrator, and it laid the groundwork for his later presidency. His experience as a food administrator during wartime is critical in understanding his policies and response to food scarcity during domestic crises in the 1930s, as well as how he approached relief efforts during the Great Depression.
