Well, no one really "invented" electricity, but you can ask
who discovered it. While people have known about the
powerful effects of lightning for thousands of years, the
first person to discover that lightning was a naturally
occuring form of electricity was Benjamin Franklin. In
1752, during a dangerous electrical storm, Franklin flew a
kite that had a metal key at the bottom of the string. When
a bolt of lightning hit the kite, a spark of electricity
flew from the key! From this experiment, Franklin invented
the lightning rod, which attracts lightning and draws it
into the ground. This saves many buildings from burning
down.
