Beauty and Brains? Hedy Lemarr and Spread Spectrum Technology

I was just watching an episode of Monumental Mysteries. They were talking about Hedy Lemarr. It showed she was not just a pretty face but also an inventor. One of her inventions was the spread spectrum Technology.

It is a shame the military did not use it during the world war but they seemed to have 'redeemed' themselves when they used it during the cold war. 

I think this site is interesting as it lists women inventors. 

I think everyone should check it out.
