His name was Alessandro Volta.  Alessandro Volta discovered the first practical method of generating electricity.  In 1800, he arranged zinc and copper discs in a column and invented the battery.  His most famous invention was the voltic pile. \n\nThese links should give you all the good stuff!

I think you're confusing Thomas Jefferson with Benjamin Franklin.\n\nAnd he didn't "make" electricity, per sey, but there were significant events which prompted his interests in researching and attempting to reproduce electricity in a controlled fashion.\n\nThe main two are lightning bolts and static shock.  While technically, these are two aspects of friction and only differ in magnitude, he considered them separate entities as one was generated by air (gaseous material) and the other by tangible objects (solid material).  The third influence in his research and discovery stems back to when he was stung by a jellyfish in his youth and pondered how so simple a creature could harness such a perplexing force.
