[edit]The UK's own Diana Dors (50's 60's starlet / sex goddess) encrypted the location of her fortune, with a hand generated code, that lasted until only recently.

Also the American starlet / sex goddess Hedy Lamarr got inspiration from a piano keyboard (black and white keys ?) to come up with AND patent 'frequncy hopping'

Although Wi-Fi is the latest New New Thing, in another sense it's something rather old. Classic-movie buffs, take note: Wi-Fi technology was patented during World War II by Hollywood starlet Hedy Lamarr and composer George Antheil, so that radio-guided torpedoes couldn't be jammed by the enemy. As an alternative to using one radio signal to direct the torpedo, their idea (U.S. patent 2,292,387) involved what they called "frequency hopping," constantly changing the radio signal between a large number of bandwidths, which is a basis for today's Wi-Fi communications
