Hedy torpedoes Hollywood

I’m sure that some of you, particularly any older readers will recognise Hedy Lamarr as an actress who starred in many films from the 30s through to the 50s. Anne Hathaway has also said that her portrayal of Catwoman in the current Batman move ‘The Dark Knight Rises‘ is based on Hedy Lamarr.

but did you know that Hedy was also somewhat of an inventor? She once approached the US military with a patent (which was granted to her and George Antheil, an avant-garde composer, in August 1942) for a torpedo guidance system. Apparently it was inspired by music and used what was described as ‘frequency hopping‘. It was not used until 1962.
