James Watt was a Scottish inventor and engineer who was most known for his creation of the Watt Steam Engine. The Watt Steam Engine used steam at near atmospheric levels that would create a partial vacuum under the piston. This creation was heavily influential in the beginning of the Industrial Revolution and would help to revolutionize Europe.
Stephenson's Rocket was one of the first steam-powered locomotives of its era. It functioned using a 0-2-2 wheel arrangement, and became the template for steam locomotives for the next 150 years. It featured multi-fire boiler tubes, two large cylinders for expelling steam, and a blast pipe that fed the exhaust steam into the cylinders. All of these different ideas were revolutionary for their time.
Edison was perhaps the most famous inventor of his time, most well known for his experiments with and later creation of the lightbulb. Edison practiced out of New Jersey, and finished his project in the early 1900s. Soon, entire cities were able to be lit up at night. Before long the idea had spread to the whole country, and America entered a new age of electric power and inventions.
Alexander Graham Bell
In 1876, Bell patented his idea for the telephone, and became the first man in the world to have successfully created a working telephone. Bell brought about new means of communication and his work was able to help link the entire world like we know today. He worked with transmitters early in his life, and finally finished the telephone in 1876.
