The Missouri Department of Revenue is a U.S. state government agency in Missouri created under the Missouri Constitution in 1945, which is responsible for ensuring the proper functioning of state and local government through the collection and distribution of state revenue, and administration of state laws governing driver licensing, and motor vehicle sale and registration.[1] Mount Etna Morris served as the Department's first Director from July 1946 until his election as State Treasurer of Missouri in November 1948, and later served again as Director from 1953 to 1956.[2]
