Answer the question at the end by quoting:

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.
During the American Civil War, Owen served in the Ordnance Commission to supply the Union army; on March 16, 1863, he was appointed to the Freedman's Inquiry Commission. The commission was a predecessor to the Freedmen's Bureau.  In 1862 Owen wrote a series of open letters to U.S. government officials, including President Abraham Lincoln and U.S. Secretary of the Treasury Salmon P. Chase, to encourage them to support general emancipation. Owen's letter of July 23, 1862, was published in the New York Evening Post on August 8, 1862, and his letter of September 12, 1862, was published in the same newspaper on September 22, 1862. In another open letter that Owen wrote to President Lincoln on September 17, 1862, he urged the president to abolish slavery on moral grounds. Owen also believed that emancipation would weaken the Confederate forces and help the Union army win the war. On September 23, 1862, Lincoln issued a preliminary version of the Emancipation Proclamation (as he had first resolved to do in mid-July). In Emancipation is Peace, a pamphlet that Owen wrote in 1863, he confirmed his view that general emancipation was a means to end the war. In The Wrong of Slavery, the Right of Emancipation, and the Future of the African Race, a report that Owen wrote in 1864, he also suggested that the Union should provide assistance to freedmen.  Toward the end of his political career, Owen continued his effort to obtain federal voting rights for women. In 1865 he submitted an initial draft for a proposed Fourteenth Amendment to the U.S. Constitution that would not restrict voting rights to males. However, Article XIV, Section 2, in the final version of the Amendment, which became part of the U.S. Constitution in 1868, was modified to limit suffrage to males who were U.S. citizens over the age of twenty-one.

IN: William Bartram (April 20, 1739 - July 22, 1823) was an American naturalist. The son of Ann (nee Mendenhall) and the naturalist John Bartram, William Bartram and his twin sister Elizabeth were born in Kingsessing, Philadelphia, Pennsylvania. As a boy, he accompanied his father on many of his travels to the Catskill Mountains, the New Jersey Pine Barrens, New England, and Florida. From his mid-teens, Bartram was noted for the quality of his botanic and ornithological drawings.

Bartram returned to Philadelphia in January 1777 and assisted his brother John in all aspects of running Bartram's Garden.  In the late 1780s, he completed the book for which he became most famous, Travels through North and South Carolina, Georgia, East and West Florida, the Cherokee Country, etc.. It was considered at the time one of the foremost books on American natural history. Many of Bartram's accounts of historical sites were the earliest records, including the Georgia mound site of Ocmulgee. In addition to its contributions to scientific knowledge, Travels is noted for its original descriptions of the American countryside. Bartram's writing influenced many of the Romantic writers of the day. William Wordsworth, Samuel Taylor Coleridge, and Francois-Rene de Chateaubriand are known to have read the book, and its influence can be seen in many of their works.  Although Bartram has often been characterized as a recluse, all evidence shows that he remained active in commercial, scientific, and intellectual pursuits well into the nineteenth century. He tutored nieces and nephews, penned a number of essays, contributed to several works anonymously, and helped run the family horticultural business. In 1802, Bartram met the school teacher Alexander Wilson and began to teach him the rudiments of ornithology and natural history illustration. Wilson's American Ornithology includes many references to Bartram and the area around Bartram's Garden. Among Bartram's more significant later contributions were the illustrations for his friend Benjamin Smith Barton's explanation of the Linnaean system, Elements of Botany (1803-04).  After the War of 1812, when many of his colleagues, contacts, and friends had died, Bartram settled into a long period of work, observation, and study at the family's garden in Kingsessing. He maintained a "Diary" that records bird migrations, plant life, and the weather. He refused a request to teach botany at the University of Pennsylvania, and in his sixties, declined an invitation from President Thomas Jefferson to accompany an expedition up the Red River in the Louisiana Territory, in 1806. He died at his home at the age of 84.
