Which person was not a Secretary of State for the US?

Omar Nelson Bradley (February 12, 1893 – April 8, 1981), nicknamed Brad, was a highly distinguished senior officer of the United States Army who saw distinguished service in North Africa and Western Europe during World War II, and later became General of the Army. From the Normandy landings of June 6, 1944 through to the end of the war in Europe, Bradley had command of all U.S. ground forces invading Germany from the west; he ultimately commanded forty-three divisions and 1.3 million men, the largest body of American soldiers ever to serve under a single U.S. field commander. After the war, Bradley headed the Veterans Administration and became Army Chief of Staff. In 1949, Bradley was appointed the first Chairman of the Joint Chiefs of Staff, and the following year oversaw the policy-making for the Korean War, before retiring from active service in 1953.

Bradley was the last of only nine people to hold a five-star rank in the United States Armed Forces.
