32 hours. Passengers on the maiden voyage included a lawyer Jones and his family from Bethlehem, Pennsylvania. His infant daughter Alexandra Jones later served as a Union nurse on a steamboat hospital in the American Civil War. The Clermont was the first real steamboat in America. While it was being built people called it "Fulton's Folly". The Clermont had sails as well as a steam engine. At each end of the boat was a short mast with a small square sail that could be unfurled when needed. The engine was in the center of the boat and was surrounded by cord wood. The engine was 24-horsepower. Above the engine was a tall and slender smoke stack. On each side was a big paddle wheel that was open and uncovered. The diameter of the paddle wheels was . The boat itself was long and wide. Its displacement was 160 tons. From 1811 until his death, Fulton was a member of the Erie Canal Commission, appointed by the Governor of New York. Fulton's final design was the floating battery . This first steam-driven warship in the world was built for the United States Navy for the War of 1812. The heavy vessel was not completed until after Fulton's death and was named in his honor. From October 1811 to January 1812, Fulton, along with Livingston and Nicholas Roosevelt (1767–1854), worked together on a joint project to build a new steamboat, , sturdy enough to take down the Ohio and Mississippi rivers to New Orleans, Louisiana. It traveled from industrial Pittsburgh, Pennsylvania, where it was built, with stops at Wheeling, Virginia; Cincinnati, Ohio; past the "Falls of the Ohio" at Louisville, Kentucky; to near Cairo, Illinois, and the confluence with the Mississippi River; and down past Memphis, Tennessee, and Natchez, Mississippi, to New Orleans some by river from the Gulf of Mexico coast. This was less than a decade after the United States had acquired the Louisiana Territory from France. These rivers were not well settled, mapped, or protected. By achieving this first breakthrough voyage and also proving the ability of the steamboat to travel upstream against powerful river currents, Fulton changed the entire trade and transportation outlook for the American heartland. Fulton was elected a member of the American Antiquarian Society in 1814. Personal life On January 8, 1808, Fulton married Harriet Livingston (1783–1826), the daughter of Walter Livingston and niece of
