Thomas Newcomen

Hello. My name is Thomas Newcomen. I lived in a place called England a very long time ago, in the late 1600s. When I was a boy, I loved to build and fix things. I worked with a strong metal called iron. I made tools and other things to help the people in my town. I was always thinking about how machines worked and how I could make them even better.

In my town, many people worked deep, deep underground in mines. They were digging for coal to help keep everyone's home warm. But there was a big, watery problem. The mines kept filling up with water. It was like a big puddle that would not go away. This made it very hard and unsafe for the workers. I thought and thought about how I could help. I knew there had to be a way to get all of that water out of the mines.

Then, I had a big idea. I decided to build a giant machine that used steam to work. Around the year 1712, I built my very first steam engine. It worked by using fire to make water very hot. When water gets hot, it makes steam. The steam was strong enough to push a big arm up. Then, when the steam cooled, the arm went down. It went up and down, up and down, just like a giant seesaw. This movement pumped all the water out of the mines so the workers could be safe.

My engine helped the miners work safely for many, many years. I lived to be 65 years old. After I was gone, other smart people used my ideas to build new and even better machines. People remember me because my steam engine was one of the very first big steps that led to a world full of amazing inventions.
