While the Spaniard first patented a steam-operated machine for use in mining, an Englishman is usually credited with inventing the first steam engine. In 1698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using steam pressure.
The first self-propelled steam engine was invented by James Watt, with the help of his assistant William Murdoch, over 60 years after Savery trialled his designs. They were able to create a working model, but they did not produce a full scale locomotive which was able to pull wagons.
