I think we've established that there are but three geniuses:
Newton, Einstein, and Mozart.
None of whom are American (asterisk Einstein).
Here's a list of people who lived here who were really good at doing stuff: Einstein, Teller, Dirac, Pauling, Schreiffer, Bell, Edison, Disney, Gates, Jobs, Bernstein, Gershwin, Whitman, Frost, Hemingway,
ok, this is tedious.
Oh yeah and Tesla (see below)
