Answer:
Peter Cooper
Step-by-step explanation:
Peter Cooper designed and built the first steam-powered locomotive in the United States in 1830 for the Baltimore & Ohio Railroad Company. Known as the "iron horse," the steam locomotive was first built by a British inventor, but Cooper was responsible for bringing it to the U.S. Prior to the steam locomotive, train carriages were pulled by horses along railways. Cooper's engine, by contrast, could pull a much heavier load much more quickly and much further than horses could. This innovation therefore had a great impact on transportation by making rail travel faster and more reliable.
