"The American Precision Museum combines the atmosphere of an original 19th century factory building with a world-class collection of historic machines. The 1846 armory building, the “Shaping America” exhibition and accompanying programs explore industrial history in the context of innovation, creative problem solving, and the impact of precision manufacturing on American history and culture" (from their website).
The website for the Museum is full of information about American inventors and the things they have dreamed up to move forward our economy and make our lives easier. As the mother of someone who is about to earn his degree in electro-mechanical engineering, I can attest to the fascination, for those so minded, of these exhibits!
