Hedy Lamarr (Portrait Treatment) 2010

1. On November 9, 1913, Lamarr was born Hedwig Eva Maria Kiesler in Vienna, Austria-Hungary, to Jewish parents Gertrud, a pianist and Budapest native who came from the "Jewish haute bourgeoisie", and Lemberg-born Emil Kiesler, a successful bank director. She studied ballet and piano at age 10. When she worked with Max Reinhardt in Berlin, he called her the "most beautiful woman in Europe". Soon the teenage girl played major roles in German movies, alongside stars like Heinz Rühmann and Hans Moser.

2. On 10 August 1933 she married Friedrich Mandl, a Vienna-based arms manufacturer 13 years her senior. Mandl prevented her from pursuing her acting career, and instead took her to meetings with technicians and business partners. In these meetings, the mathematically talented Lamarr learned about military technology. Otherwise she had to stay at the castle Schloss Schwarzenau. She later related that, even though Mandl was part-Jewish, he was consorting with Nazi industrialists, which infuriated her. In Ecstasy and Me, Lamarr wrote that dictators Benito Mussolini and Adolf Hitler both attended Mandl's grand parties. She related that in 1937 she disguised herself as one of her maids and fled to Paris, where she obtained a divorce, and then moved on to London. According to another version of the episode, she persuaded Mandl to allow her to attend a party wearing all her expensive jewelry, later drugged him with the help of her maid, and made her escape out of the country with the jewelry.

3. Avant garde composer George Antheil, a son of German immigrants and neighbor of Lamarr, had experimented with automated control of musical instruments, including his music for Ballet Mecanique, originally written for Fernand Léger's 1924 abstract film. This score involved multiple player pianos playing simultaneously. Together, Antheil and Lamarr submitted the idea of a secret communication system in June 1941. On August 11, 1942, US Patent 2,292,387 was granted to Antheil and "Hedy Kiesler Markey", Lamarr's married name at the time. This early version of frequency hopping used a piano roll to change between 88 frequencies and was intended to make radio-guided torpedoes harder for enemies to detect or jam. Lamarr's and Antheil's frequency-hopping idea serves as a basis for modern spread-spectrum communication technology, such as COFDM used in Wi-Fi network connections and CDMA used in some cordless and wireless telephones.

4. In 1965 Lamarr was arrested for shoplifting in Los Angeles; the charges were eventually dropped. In 1991 she was arrested on the same charge in Florida, this time for $21.48 worth of laxatives and eye drops. She pleaded "no contest" to avoid a court appearance, and in return for a promise to refrain from breaking any laws for a year, the charges were once again dropped. The publication of her autobiography Ecstasy and Me (1967) took place about a year after accusations of shoplifting, and a year after Andy Warhol's short film Hedy (1966), also known as The Shoplifter. The controversy surrounding the shoplifting charges coincided with a failed return to the screen in Picture Mommy Dead (1966). The role was ultimately filled by Zsa Zsa Gabor. Ecstasy and Me begins in a despondent mood, with reference to this: "On a recent evening, sitting home alone suffering and brooding about my treatment at the police station because of an incident in a department store, and being replaced by Zsa Zsa Gabor in a motion picture (imagine how that pleased the ego!) I figured out that I had made – and spent – some thirty million dollars. Yet earlier that day I had been unable to pay for a sandwich at Schwab's drug-store."

5. Lamarr died in Casselberry, Florida (near Orlando) on January 19, 2000. In 2005, the first Inventor's Day in German-speaking countries was held in her honor on November 9, on what would have been her 92nd birthday.
