On November 9, 1914, in Vienna, Austria, Hedwig Eva Kiesler was born. Later known as Hedy Lamarr, she was the only child of wealthy Jewish parents. During her childhood, she attended private schools and was an eager and curious student, excelling in scientific areas.
However, her knack for science and engineering was swiftly overlooked in favour of her physical appearance. Expected to conform to feminine ideals of the time, her beauty was greatly rewarded.
At the age of 16, the spotlight landed on her looks; when she was discovered by director Max Reinhardt. After landing a debut in film with a small role in 1930, Lamarr moved to Berlin, where she eventually booked a lead role in the controversial 1933 film Ecstasy.
The nudity and scandalous nature of this film gave her instant notoriety. The film was banned in multiple countries, including the USA, and Lamarr became known as “The Ecstasy Girl”.
Also in 1933, at the age of 19, she married wealthy arms dealer Fritz Mandl. At 30 years her senior, Mandl’s marriage to Lamarr was short lived and unhealthy. Mandl’s controlling and commandeering nature, as well as his close ties to Nazi sympathisers, made her desperate for escape –and escape she did, fleeing to Paris disguised as a maid in 1937.
There, she was able to obtain divorce from Mandl and subsequently leave Europe due to the rise in anti-semitic Nazi ideals. Lamarr would marry a further 5 times, divorcing her 6th and last husband (Lewis William Boies Jr.) in 1965.
On an ocean liner to the U.S, Lamarr signed a contract with MGM management and Louis B. Mayer, whom she had previously met in London. At their first meeting, she was offered a contract with MGM, for $125 a week, but turned it down in order to negotiate a better salary.
After successfully negotiating a contract, Mayer and Lamarr collaborated to create her new image, dreaming up the onscreen persona of Hedy Lamarr. She became an instant sensation with a breakout role in the 1938 film Algiers; a strikingly beautiful, alluring, and exotic new star.
While her beauty was publicly adored and captured on screen, her inventive and technological genius was hidden. As the Second World War began, Lamarr considered using her abilities to help the war effort. Her knowledge of arms and weaponry from her first marriage would also be of use. She was particularly intrigued by “frequency skipping”, a technology which could allow Allied ships to communicate using more than one signal, preventing interference by German ships.
This remained little more than an idea until 1940, when she met her Hollywood neighbour, composer George Antheil. The two spoke about weaponry and radio-controlled torpedoes, including how to change frequencies and prevent them from interception.
With this idea, they designed a system to guide torpedoes. Lamarr’s idea of frequency-hopping and Antheil’s past experience with 16-player pianos in his Ballet Mecanique came together to create their radio guidance system.
They were granted a patent on August 11, 1942, but Lamarr was listed on the patent under her previous married name, Hedy Kiesler Markey. Lamarr and Antheil had little success convincing others of their idea. The US Navy found the system to be too bulky for use with a torpedo.
Frequency Hopping Spread Spectrum (FHSS) is now used in WiFi technology, where signal hops between frequencies hundreds of times a second. Because of this, Lamarr is now known as not “The Ecstasy Girl” but instead, “the Mother of WiFi”
The advanced nature of her idea meant that Lamarr appeared in a further 20 films, passing away in the year 2000 without ever seeing the unimaginable changes that her invention sparked in the world.
One can’t help but wonder who Hedy Lamarr would have been if she was celebrated for her genius rather than her looks. During her life, she grew to resent her beauty for holding her back. She said, “My face is my misfortune”, and described it as “a mask I cannot remove. I must live with it, I curse it”.
Shoved into a carefully restricted box by her Hollywood career and the media, she was told she couldn’t be two things at once. Her own daughter, Denise Loder-DeLuca, said, “it's outrageous she wasn't taken seriously—she was told just go back to being pretty, go back to your movies."
In a world that praised her looks, Hedy Lamarr proved that brilliance and beauty are never mutually exclusive, operating on a frequency of her very own.
