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.

With advancing industrialisation in the 19th century, the demand for transport capacity on the waterways increased markedly. But this industrialisation also revolutionized the methods of transport themselves. The invention of the steam engine meant that, for the first time, a motor was now available to power ships independently of wind and wave. The power of the first steam engines was, however, relatively low whilst, at the same time, they were very heavy. So attempts were made to utilize its power in the most effective way to move ships.
