George C. Marshall was a military and civilian leader. His most important contributions were during and following World War II. He became Chief of Staff of the Army in 1939. Marshall served as senior military advisor to Presidents Roosevelt and Truman. Winston Churchill referred to Marshall as the “organizer of victory” because of his leadership and management abilities.
After the war, he served as Secretary of State and oversaw the reconstruction of war-ravaged Europe. This successful endeavor earned him the Nobel Peace Prize and became known as the Marshall Plan in his honor. The armed forces were in disarray at the start of the Korean conflict in 1951. President Truman tasked Marshall to reorganize the U.S. military efforts in Korea shortly after his appointment as Secretary of Defense.
Marshall was the U.S. representative to the coronation of Queen Elizabeth II in 1952. He was also president of the American Red Cross.
