Hedy Lamarr (; born Hedwig Eva Maria Kiesler, November 9, 1914 -  January 19, 2000) was an Austrian-born American film actress and inventor. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.
First marriage
On August 10, 1933, Lamarr married Mandl, an Austrian military arms merchant and munitions manufacturer who was reputedly the third-richest man in Austria. She was 18 years old and he was 33. In her autobiography Ecstasy and Me, she described Mandl as an extremely controlling husband who strongly objected to her simulated orgasm scene in Ecstasy and prevented her from pursuing her acting career. She claimed she was kept a virtual prisoner in their castle home, Schloss Schwarzenau.  Mandl had close social and business ties to the fascist government of Italy, selling munitions to Mussolini, and although like Hedy, his own father was Jewish, had ties to the Nazi government of Germany, as well. Lamarr wrote that Mussolini and Hitler attended lavish parties at the Mandl home. Lamarr accompanied Mandl to business meetings, where he conferred with scientists and other professionals involved in military technology. These conferences were her introduction to the field of applied science and nurtured her latent talent in science.  Lamarr's marriage to Mandl eventually became unbearable, and she decided to separate herself from both him and her country. In her autobiography, she wrote that she disguised herself as her maid and fled to Paris, but by other accounts, she persuaded Mandl to let her wear all of her jewelry for a dinner party, then disappeared afterward. She writes about her marriage:  I knew very soon that I could never be an actress while I was his wife.... He was the absolute monarch in his marriage.... I was like a doll. I was like a thing, some object of art which had to be guarded--and imprisoned--having no mind, no life of its own.
