American businessman (1785 1851)
Shreve was also instrumental in breaking the Fulton Livingston monopoly on steamboat traffic on the lower Mississippi. He was the first riverboat captain to travel the Ohio and Mississippi rivers to New Orleans and back, as well as the first to bring a keelboat from the Ohio River up the Mississippi to the Fever River in Illinois. Shreve also made significant improvements to the steamboat and the steam engine, such as separate boilers to power side paddlewheels independently, horizontal cylinders, and multiple decks to allow for passengers and entertainment. to Israel Shreve, a Quaker farmer who had served as a colonel in the American Revolution, and the former Mary Cokely

In 1807, Shreve was a captain and built a barge of 35 tons, at Brownsville, Pennsylvania, on the Monongahela River. He manned with a crew of ten men for a voyage to St. Louis, which he reached in December of that year. After purchasing a cargo of furs, he returned to Pittsburgh and forwarded them to Philadelphia. He continued this trade for three years with considerable profit, as each voyage was on his own account. In 1810, Shreve decided to open a new line of business, lead trade. On 2 May, he left in a new barge of 35 tons manned by 12 men and made the trip from St. Louis to where Galena, Illinois, was later built, in 14 days. He remained until July 1 busily employed in traffic with the natives, buying 60 tons of lead. He was therefore compelled to build a flat boat, and buy a Mackinaw boat, to transport his return cargo. His flotilla reached St Louis in 12 days, the beginning of the American lead trade on the Upper Mississippi. He took his cargo to New Orleans and then shipped it to Philadelphia, earning upwards of $11,000. In 1847 that trade equalled in value about $3,000,000 annually, estimating only the shipments from Fever River. In 1810, there were less than 10 small settlements between Louisville and the mouth of the Ohio River and about the same number between the latter and Vicksburg. Shreve never repeated the trip to Galena, as his success induced others to send 6 barges to Galena. Upon his return to Brownsville that year he built a barge of 95 ton capacity, and began regular voyages between Pittsburgh and New Orleans for the next 4 years. After loading his boat with cargo, Shreve and crew hauled and poled the vessel 2200 mile (3541 km) against strong river currents, probably reaching Brownsville before July 1814.
