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.
There are at least a few different ways you can answer this question. That is because, as is the case with a lot of inventions, the first person who came up with any sort of steam engine is not the person who is most famous. The first person you can credit is Thomas Savery. He invented a crude steam engine in 1698. The next one is Thomas Newcomen. He and a partner built a steam engine in 1712 that was able to pump water up out of mines. The most famous inventor of the steam engine was James Watt.
