Who was the Chief of Staff of the US Army during World War II?

George C, Marshall Jr. (b. December 31, 1880 – d. October 16, 1959) was an American army officer and statesman. He rose through the United States Army to become Chief of Staff of the US Army under Presidents Franklin D. Roosevelt and Harry S. Truman, then served as Secretary of State and Secretary of Defense under Truman. Winston Churchill said that Marshall was the "organizer of victory" for his leadership of the Allied victory in World War II.

After the war, Marshall spent a frustrating year trying and failing to avoid the impending civil war in China. As Secretary of State, Marshall advocated a US economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of his work during this period of time, he was awarded the Nobel Peace Prize in 1953.

General Marshall was the last Philippine–American War veteran to serve as Chief of Staff. He attained mandatory retirement age of 64 in 1944, but continued to serve as Chief of Staff during WWII. He was relieved from active military duties in November 1945. He implemented the Marshall Plan in 1953 and later he served as Secretary of Defense during the Korean War.
