Robert Dale Owen (November 7, 1801 - June 24, 1877) was a Scottish-born 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. charge d'affaires (1853-58) to Naples. Owen was a knowledgeable exponent of the socialist doctrines of his father, Robert Owen, and managed the day-to-day operation of New Harmony, Indiana, the socialistic utopian community he helped establish with his father in 1825.

After his first term in the Indiana legislature and two unsuccessful campaigns for election to the U.S. Congress in 1838 and in 1840, Owen was elected as a Democrat to the U.S. House of Representatives in 1842. He served from 1843 to 1847 in the Twenty-eighth and Twenty-ninth Congresses. Owen was chairman of the Committee on Roads and Canals during the Twenty-eighth Congress. He was also involved in the debates about the annexation of Texas and an Oregon boundary dispute in 1844 that led to the establishment of the U.S-British boundary at the 49th parallel north, the result of the Oregon Treaty (1846). While serving as a member of Congress, Owen introduced and helped to secure passage of the bill that founded the Smithsonian Institution in 1846. Owen was appointed to the Smithsonian Institution's first Board of Regents and chaired its Building Committee, which oversaw the construction of the Smithsonian Institution Building in Washington, D.C., and recommended James Renwick, Jr. as architect, James Dixson and Gilbert Cameron as the contractors, and the Seneca Quarry for its distinct, dark-red sandstone. Owen, his brother David Dale Owen, and architect Robert Mills, were involved in developing preliminary plans for the Smithsonian Building. These early plans influenced Renwick's choice of the Romanesque Revival architectural style (sometimes referred to as Norman-style architecture) and his three-story design for the building, which was finally selected, although not without controversy. Owen's book Hints on Public Architecture (1849) argued the case for the suitability of Renwick's Romanesque Revival (Norman) architectural style for public buildings such as the Smithsonian "Castle," which he discussed in detail. Seven full-page illustrations and details of the building's architectural elements were prominently featured in the book, leading some to criticize Owen for his bias toward Renwick and his preference for Norman-style architecture over other popular styles.
