By whom and when was copper discovered?
The metal copper has been known since very ancient times. Chances are it was first produced by accident. Someone would have built a campfire and used rocks around the edge of the fire to contain it (as we still often do to this day) and if this person had happened to use a form of copper ore as the rocks for his campfire, they could have gotten hot enough that copper would have melted out of the rocks. And then, if this person was observant enough, he or she would have investigated further, to see if this strange substance had any particular uses (which of course it does) and whether more of it could be melted (or refined) out of more rocks (which of course it can).
