On August 26, 1791, John Fitch and James Rumsey, rivals battling over claims to the invention, each were granted a federal patent for the steamboat. They devised different systems for their steamboats. Four years earlier, on August 22, 1787, Fitch demonstrated a steamboat—a Watt-type engine with a separate condenser that transmitted power to oars mounted to stroke in a paddle fashion. The forty-five-foot craft launched on the Delaware River in the presence of delegates from the Constitutional Convention. Rumsey’s craft was powered by direct force—jet propulsion. Fitch went on to build a larger steamboat that carried passengers and freight between Philadelphia and Burlington, New Jersey.
Nonetheless, Robert Fulton is generally credited as the inventor of the steamboat. In 1814, Fulton and Edward Livingston, the brother of Robert R. Livingston, brought commercial success to steamboating when they began to offer regular steamboat service between New Orleans, Louisiana, and Natchez, Mississippi. The boats traveled at the rates of eight miles per hour downstream and three miles per hour upstream. In 1816, Henry Miller Shreve launched his steamboat Washington, which completed the voyage from New Orleans to Louisville, Kentucky, in twenty-five days. Steamboat design continued to improve, so that by 1853, the trip to Louisville took only four and one-half days.
