About this source

What it is

This is an article by Professor B. H. Thurston of the Stevens Institute of Technology, published in Popular Science Monthly in December 1877. It traces the development of the steam engine, with a section on the period from 1700 to 1800 covering Thomas Newcomen, John Cawley (or Calley), and James Watt.

Why it matters

The article places Watt's work in a longer history of invention, showing that he built on earlier efforts by Newcomen and Cawley rather than inventing the steam engine from nothing. It reflects how, a century after Watt's work, popular science writers explained his contribution to the public.

Look closer

  • Why does the article discuss Newcomen and Cawley before getting to Watt?
  • How does describing earlier inventors change the way we think about Watt's achievement?
  • What does it mean that this article was written for a general audience almost a century after Watt's work?
