west of the Allegheny Mountains. At the time of Owen's death in 1860, his museum included some 85,000 items. Among Owen's most significant publications is his Report of a Geological Survey of Wisconsin, Iowa, and Minnesota and Incidentally of a Portion of Nebraska Territory (Philadelphia, 1852). Several men trained Owen's leadership and influence: Benjamin Franklin Shumard, for whom the Shumard oak is named, was appointed state geologist of Texas by Governor Hardin R. Runnels; Amos Henry Worthen was the second state geologist of Illinois and the first curator of the Illinois State Museum; and Fielding Bradford Meek became the first full-time paleontologist in lieu of salary at the Smithsonian Institution. Joseph Granville Norwood, one of David Dale Owen's colleagues and coauthors, also a medical doctor, became the first state geologist of Illinois (1851–1858). From 1851 to 1854, the Illinois State Geological Survey was headquartered in New Harmony. Richard Owen (1810–1890), Robert Owen's youngest son, came to New Harmony in 1828 and initially taught school there. He assisted his brother, David Dale Owen, with geological survey and became Indiana's second state geologist. During the American Civil War, Colonel Richard Owen was commandant in charge of Confederate prisoners at Camp Morton in Indianapolis. Following his retirement from the U.S. Army in 1864, Owen became a professor of natural sciences at Indiana University in Bloomington, where an academic building is named in his honor. In 1872 Owen became the first president of Purdue University, but resigned from this position in 1874. He continued teaching at IU until his retirement in 1879. Public service and social reform Robert Dale Owen, eldest son of Robert Owen, was a social reformer and intellectual of national importance. At New Harmony, he taught school and co-edited and published the New Harmony Gazette with Frances Wright. Owen later moved to New York. In 1830 he published "Moral Philosophy," the first treatise in the United States to support birth control, and returned to New Harmony in 1834. From 1836 to 1838, and in 1851, Owen served in the Indiana legislature and was also a delegate to the state's constitutional convention of 1850. Owen was an advocate for women's rights, free public education, and opposed slavery. As a member of the U. S. House of Representatives from 1843 to 1847, Owen introduced a bill in 1846 that established the Smithsonian Institution. He also served as chairman of the Smithsonian Building Committee.
