Beauty AND brains — Not too shabby, right?

Hedy Lamarr: Hollywood Sex Symbol, Tech Geek…She was a glamorous movie star of the 1930s and ’40s, a taboo-breaking beauty who is credited with simulating the first on-screen orgasm (and also appearing nude) in a 1933 film called Ecstasy.

But Hedy Lamarr was a trailblazer in more ways than one: Fascinated by science and eager to find a way to help the Allies during World War II, Lamarr came up with a way to make radio signals jump between frequencies, and thus prevent the signals from becoming jammed. After Lamarr and a partner obtained a patent for the invention in 1942, she gave it — at no charge — to the U.S. Navy, which began using it in the 1960s. Today, Lamarr’s breakthrough is used in technology like the Bluetooth wireless device.
