Hedy Lamarr - Beauty and Brains
Lamarr was certainly glamorous -- even in the "Golden Age" of Hollywood, when competition for "The Most Beautiful Woman in Films" was never more fierce -- but she was far from stupid.
The Austrian-American movie star's native intelligence, her keen interest in new technologies, and a chance meeting with an avant-garde composer, led her to the concept of "frequency hopping" and a 1942 patent for a torpedo guidance system that was a generation ahead of its time. It was this invention that has, in large part, laid the foundation for the cell phone technology we rely on today.

Hedy Lamarr was born Hedwig Eva Maria Kiesler, near Vienna, Austria, on November 19, 1913. Her father, Emil Kiesler, was a successful bank director and her mother, Gertrud Lichtwitz, a pianist. During her late teens, Hedy studied acting at Max Reinhardt's famous school in Berlin.
Her first film appearance, in 1930, at the age of 17, was a bit part in the German film Das Geld liegt auf der Straße (Money on the Street), followed by larger roles in Die Frau von Lindenau (Storm in a Water Glass), Die Abenteuer des Herrn O. F. (The Trunks of Mr. O. F.), both 1931, and Man braucht kein Geld (We Don't Need Money) in 1932.
It was her appearance in the 1933 Chek film Ekstase (Ecstasy), however, with its scandal-making footage of the young actress running nude through the forest, that propelled Hedy Kiesler Lamarr to early fame. Ecstasy was banned by the US government and denounced by the Pope -- and Hedy's husband was even less happy about it.

Bad Marriage to Friedrich Mandl

Ecstasy and Me:
My Life As A Woman


In her autobiography, Ecstasy and Me, Lamarr describes Mandl as "extremely controlling." She was often required to attend business and technical meetings with him, or stay confined to their home. She suggests that Fritz Mandl consorted with Nazi industrialists, despite being partly Jewish; though his political bent was more to Austrofascism than Nazism, the autobiography reports that Benito Mussolini and Adolf Hitler attended Mandl's parties.
Several versions have been told of how, exactly, Hedy's separation from her first husband was accomplished, including one in which she escaped only by disguising herself as a maid. She fled to Paris where, in 1937, she obtained a divorce from Friedrich Mandl.

US Patent 2,292,387: Lamarr & Antheil

The most celebrated invention of frequency hopping was that of actress Hedy Lamarr and composer George Antheil, who in 1942 received patent number 2,292,387 for their "Secret Communications System."

Richard Rhodes on Hedy's Folly
She donated the patent to the U.S. Navy in 1942. The Navy ignored it, but in the early 1950s it was taken up by a defense contractor and applied to a submarine listening device. Then other defense contractors used it to make jam-proof radio systems for the U.S. military.
In the early 1980s, when the military declassified it, it became the basis for Bluetooth, GPS, wireless telephones and many other present-day communication systems.

Hedy Lamarr: After the War
By then, too, she was the mother of three -- James Lamarr Markey (born in 1939), Denise Loder (born 1945), and Anthony Loder (born 1947). Perhaps her image as a "screen siren" was no longer as comfortable a role for her as it once had been?
In any case, the taste of the cinema-going North American public was changing, as the drive for progress and prosperity took the place of the wartime yen to escape harsh realities through the big silver screen.
