    Try Googling these two names Pony.
    John Ericsson and John Frank Stevens.

    Well… Two major developments actually came together to replace the paddle wheel…
    One was the invention of the screw propeller, the other was great improvements made to the
    steam engine.

    Just about everything you want to know about the history of the paddlewheel, it’s creation, glory days, and demise, can be found at the link below – fun site, great pictures, great information.

    If this question has anything to do with school – the information at the link below will earn you an "A+" I guarantee it…

    By 1870, a number of inventions, such as the screw propeller and the triple expansion engine made trans-oceanic shipping economically viable. Thus began the era of cheap and safe travel and trade around the world.
