Tons of people get left out of history. Ever heard of Bayard Rustin? He should get most of the credit given to Martin Luther King Jr and Rosa Parks. Drives me nuts when I go to work every day at an elementary school and all I see is MLK this and Rosa Parks that.

And then there's Columbus.

BTW, Edison shouldn't ever get the credit for "inventing" electricity. Its a natural resource. For thousands of years people have been using electricity. For sacrifices during a lightning storm there's none better. And what about God judging you by means of being put out in a storm. If electricity fries you, you've been judged. These former electricity users just didn't know how to harness electricity for future use at their own will.
