Robert Dale Owen (November 7, 1801 – June 24, 1877) was a Scottish-born Welsh social reformer who immigrated to the United States in 1825, became a U.S. citizen, and was active in Indiana politics as member of the Democratic Party in the Indiana House of Representatives (1835–39 and 1851–53) and represented Indiana in the U.S. House of Representatives (1843–47). As a member of Congress, Owen successfully pushed through the bill that established Smithsonian Institution and served on the Institution's first Board of Regents. Owen also served as a delegate to the Indiana Constitutional Convention in 1850 and was appointed as U.S. "chargé d'affaires" (1853–58) to Naples.
