From here. One of my personal favorites is james eads, who built the eads bridge. He taught himself from age 13 onward out to copulate structures and that sort of thing. Forme basically how to structures and that sort of thing. And he basically taught himself how to build a stable tableting machine. He would go down and salvage these and sell them, so the eads bridge was significant because the time it was the longest arched bridge in the world at over 6000 feet long, and people were kind of terrified of it. They really did not have a lot of faith in it. Today we think steel is very strong. They thought it looked like a skeleton and was ready to fall over at any time under its own weight, so eads was really impressive to me just because of a National Story associate with him but also the fact that he taught himself how to become an engineer.
