The first successful trial run of a steamboat had been made several years earlier in the United States by inventor John Fitch, on the Delaware River on August 22, 1787. Attendees included delegates from the Constitutional Convention, who were observing while taking a break from their summer-long sessions at Independence Hall. The steamboat was propelled by a bank of oars on either side of the boat. The following year Fitch launched a boat powered by a steam engine driving several stern-mounted oars. These oars paddled in a manner similar to the motion of a swimming duck's feet. With this boat he carried up to thirty passengers for hire on numerous round-trip voyages on the Delaware River between Philadelphia and Burlington, New Jersey.
Steamboat
For most of the 19th century and part of the early 20th century, trade on the Mississippi River was dominated by paddle-wheel steamboats. Their use generated rapid development of economies of port cities; the exploitation of agricultural and commodity products, which could be more easily transported to markets; and prosperity along the major rivers. Their success led to penetration deep into the continent, where "Anson Northup" in 1859 became first steamer to cross the Canada–US border on the Red River. They would also be involved in major political events, as when Louis Riel seized "International" at Fort Garry, or Gabriel Dumont was engaged by "Northcote" at Batoche. Steamboats were held in such high esteem that they could become state symbols; the Steamboat "Iowa" (1838) is incorporated in the Seal of Iowa because it represented speed, power, and progress.
