Harry S. Truman (along with Bess and Margaret Truman) made the last of several visits to Maryville on August 3, 1962 when he dedicated the current post office. Truman had extensive ties to Maryville. During World War I Truman was a member of the 129th Field Artillery Regiment in the Missouri National Guard, which is headquartered in Maryville. Truman commanded Battery D in the war of the 129th. The 129th official motto is "Truman's Own" because of the affiliation. During the Meuse-Argonne Offensive during World War I in 1918, Truman prophetically told his troops, ""Right now, I'm where I want to be – in command of this battery. I'd rather be here than president of the United States." Among the original 129th soldiers was Edward V. Condon (1893–1974) who later operated the Condon Corner Drug Store across the street on the Square after the war. Truman dedicated the 129th's armory on the northwest side of Bearcat Stadium on the college campus on February 20, 1955.
