Old Hollywood glamour combined with serious substance

FH-SS ever heard of it? No? If you even know who Hedy Lamarr was you'd have been one up on me until a few days ago. Hedy was a legendary Hollywood beauty, an actress and an inventor. She filed a bunch of patents including one for the aforementioned FH-SS which stands for frequency hopping spread spectrum used in most mobile devices. I was fascinated by the concept of a actress whose ideal night doesn't involve falling out of a nightclub, or crashing their car whilst intoxicated. Hedy had an engineer's brain and this is a fascinating story.
