According to tradition, Jesse Kirk, Kirksville's first postmaster, shared a dinner of turkey and whiskey with surveyors working in the area on the condition that they would name the town after him. Not only the first postmaster, Kirk was also the first to own a hotel and a tavern in Kirksville. Contrary to popular belief, the name of the city has no connection to John Kirk, onetime president of Truman State University from 1899 to 1925.
