    Most other web-sites suggest the cotton gin actually increased the amount of slavery in the south because it made cotton production much more profitable. It is claimed the number of cotton plantations doubled in the period after the invention of the cotton gin. And while the labour needed to remove the seeds was reduced, it did not reduce the labour needed to grow and pick the cotton. Can anyone advise me if this is correct?

    It is absolutely astounding that automatic weapons (particularly the machine gun) are not included in either the 19th or 20th century greatest inventions. I’m not even going to explain why 🙂

    Excuse me, but Nikola Tesla invented electricity, not Edison. Edison took credit for Tesla’s invention and left Tesla with nothing. Tesla also invented the backing behind the radio, again, not Edison. Get it right.

    Yeah, well, they were probably just copying us.

    Uhh… antiseptics should be at the top of the list, It’s strange that it’s not even in the top 10.

    The printing press, and it’s ability to spread information throughout the world, is undoubtably the most important invention of all time. Nothing else is even a close second.

      It wasn’t invented in the 19th Century, though.

    The Cotton Gin actually increased the need for slave labor. As others have so generously pointed out, it did not pick cotton, but processed it at a much faster rate than humans could. this meant that the plantation owners could grow more cotton because they could process it so much faster, therefore requiring even more slaves to tend to the fields… where the hell did you do your research on that one?

    The telephone 'but was to forever change the country'?

    I would it would imagine it would forever change the world.

    Which country do you speak of? – Canada, where the telephone was invented?

    This list is ill-conceived at best. Without the rotary press, invented in the 1840s, America and the world would be entirely different places. It redefined news and how people learned.

    The cotton gin is a mechanical device which removes the seeds, seed hulls, and other small objects from the fibers of cotton, a process which until that time had been very labor-intensive.

    just thought i'd throw in a definition!

    No, the cotton gin didn't pick cotton, it cleaned and baled it. They still needed slaves to grow, harvest, and bring it to the gin.
