Henry Miller Shreve

Henry Miller Shreve (October 21, 1785 – March 6, 1851) was an American inventor and steamboat captain who removed obstructions to navigation of the Mississippi, Ohio and Red rivers. Shreveport, Louisiana, was named in his honor.

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.
