Inventors come from all walks of life, from artist and barbers to scientists and statesmen. Some, such as Archimedes and Thomas Jefferson, are better know for other achievements in their lives. People like Richard Arkwright and Thimas Edison, on the other hand, are famous for inventing things that have changed the way we live. What they all share in common is a passion for exploring ideas, solving problems, and never giving up untill the job is done.
