After leaving the library (last stop in installment #2) we headed upstairs to the precision machinery floor..

Behind this wall below, in 1888, in a small room long since dismantled, Thomas Edison and W. K. L. Dickson created the first motion picture camera.

I think the electric light is probably the thing Thomas Edison is most famous for .  Although he did not invent the first electric light, Edison made the first practical electric light bulb that could be manufactured and used in the home. He also invented other items that were needed to make the light bulb practical for use in homes including safety fuses and off/off switches for light sockets.

Our last stop was downstairs to the heavy machinery floor.

I myself have no idea what this sign means but that doesn’t mean you all don’t 🙂

I can’t imagine the noise level when all these machines were in use at the same time.

 I really enjoyed learning about this incredible man.
