In 1837, in Illinois, John Deere, a typical blacksmith, was working on his craft when suddenly he found a piece of metal, a blade from a mill, that was lying on the ground. Thinking about the difficulties that farmers up until then experienced with the sometimes hard soild of the prairies, Deere realized the potential of the blade and crafted what is today known as the steel plow.
