The steam engine can easily be considered the single most important invention of the entire industrial revolution. There is not one part of industry present in today's society that can be examined without coming across some type of reference or dependence upon the steam engine. But, who deserves the credit for this great invention? Some give the credit to James Watt while others claim that Thomas Newcomer was the original inventor. However, the idea of the using the power of steam to the advantage of human beings has been around practically since the beginning of time. But, no practical uses for steam emerged until the 17th century.
