Hoover was born to a Quaker family in West Branch, Iowa. He took a position with a London-based mining company after graduating from Stanford University in 1895. After the outbreak of World War I, he became the head of the Commission for Relief in Belgium, an international relief organization that provided food to occupied Belgium. When the U.S. entered the war, President Woodrow Wilson appointed Hoover to lead the Food Administration, and Hoover became known as the country's "food czar". After the war, Hoover led the American Relief Administration, which provided food to the inhabitants of Central Europe and Eastern Europe.
