Hedy Lamarr. Yes, we should thank that same actress for using the Internet Wi-Fi and GPS. How did it happen?
Hedy was born in Austria in 1913. Being a Jew, she hid her origins in every way. In 1933, Hedy starred in the film “Ecstasy”. It was the first time in the history of cinema when a completely naked actress was shown. In many countries the film was banned. The parents of the actress worried about their daughter’s reputation. Therefore, they married her to the arms tycoon Fritz Mandl. He was also a Jew. In addition, most importantly, it was Fritz who produced grenades and cartridges for Hitler.
Her husband was very jealous, and Hedy had to leave the movie. But she accompanied her husband to military laboratories and quickly figured out the principle of the action of anti-ship weapons and guidance systems.
Lamarr was not happy with her husband. Once Hedy escaped. The girl ran first to London, and then to the USA. In Hollywood, she was noticed by Louis Mayer, the founder of Metro Golden Mayer.
When radio-guided missiles were adopted, a serious problem arose. Opponents easily violated the guidance of the torpedo, revealing its frequency. Then Hedy Lamarr, together with George Antheil, whom she had met in London, came up with how to protect the torpedo control over the radio (she also assisted with the creation of controlled torpedoes).
Here’s how it worked: a random code was used on the transmitter that would change the transmission channel. At the same time, frequency transitions were synchronized on the receiver. The invention of Lamarr and Antheil became the basis of Spread Spectrum – the connection with the extended spectrum, which is used everywhere. These are GPS and Wi-Fi.
Lamarr was forgotten in the last years of her life. She lived poorly. Moreover, Hedy was engaged in litigation about slander and unauthorized use of her name. For example, in 1998 Corel Draw, a program for graphic design, used a portrait of an actress. Hedy immediately filed a lawsuit, but her claim was dismissed.
