Benjamin Franklin

Coolest od dude in American History and a bonafide genius.

Amazing man.  He was a philosopher, writer, scientist, politician, theologian, inventor, and all around smart guy.

He was a pimp, too. Not in the literal sense, of course, but the ladies all knew about him...

Scientist, inventor, diplomat, politician, author, publisher, and I'm sure a few things that I can't think of right now. While the old phrase "jack of all trades, master of none" seems to apply to many people, the same can't be said of Franklin. It seems like he really was good at everything.
