An odd 'history of science' question...

Sup /sci/! I'm just wondering, and my apologies if this seems like kind of a broad question, but can you think of any presidents, kings, prime ministers, etc.--you know, national leaders or notable politicians--who have been scientists? Off the top of my head I can think of Thomas Jefferson, who aside from his accomplishments as President of the U.S also did some work in paleontology and invented a few nifty things. Can any of you guys think of any other politicians whose interests encompassed math and science as well as law? Thanks very much in advance.

James Garfield derived a novel proof of the pythagorean theorem while working in the house of representatives (halfway down): http://mathworld.wolfram.com/PythagoreanTheorem.html

Lincoln was a ballistics expert.

George W Bush has an MBA in business administration and is the first president to hold an MBA.

notable politician - Ben Franklin

Jefferson wasn't a scientist per se, but he had the temperment of one.

Adolf Hitler, an expert in Jewish problem.
