Beauty is a tricky gift for a woman. It can open doors to winning beauty contests, finding boyfriends, lovers, and powerful patrons, but it can also slam doors in your face if your ambitions rise above being someone’s trophy. As Rosalind Russell warbled years ago in the movie Wonderful Town “Just throw your knowledge in his face; He’ll never try for second base…” The amazing beauty of Hedy Lamarr brought her international fame as a movie star, but when she used her talents as a mathematician and inventor her contributions were

The story of how Hedy Lamarr came to live in Hollywood was not an unusual one for the 1930s when the movie capital was a beacon to so many European artistic exiles. She had been born in Vienna as Hedwig Eva Marie Kiesler, the daughter of a prosperous banker and his concert pianist wife. As an only child she was encouraged by her devoted parents to develop her interests in art and science. She studied drama, decided she wanted to become a Hollywood actress, and while still a teenager talked herself into a small role in a film. At 16 she dropped out of school and determined to become a movie star. Her startling beauty eased her way into films and she made the movie Ecstasy, which made her famous, more because of the brief nude scenes than because of her acting.

Soon she was being courted by Friedrich Mandl, one of the richest men in Austria, and the owner of a munitions factory. By the time she was 19, Hedy was married and living a life of luxury, but the price she had to pay was Mandl’s insistence that she give up her career. She later described her life with him as being “like a doll in a beautiful, jeweled case”. She left the world of the theater and gave dinners for businessmen and their wives. She wasn’t interested in munitions or weapons, but she heard many discussions about these subjects which later provided the basis for her inventions.

By 1937, Hedy had suffered enough from the restrictiveness of her marriage with Mandl. She wanted to return to acting and finally worked up the courage to do that as well as to file for divorce and to escape to London. From there she booked passage for America on the same ship that Louis B. Mayer was traveling on. Her beauty and her popularity with the male passengers persuaded Mayer that she would be an asset to his movie studio, so he offered her a contract.

Life in Hollywood was not quite as easy or as much fun as she had expected. She had to learn English, lose some weight, and wait until Mayer found suitable roles for her. She was not very interested in the socializing that was a part of Hollywood life. She didn’t drink and she was concerned about the war looming over Europe. Instead of spending her time at parties, she set aside a corner of her living room as her “inventing” space. Her hobby was trying to come up with ideas for new gadgets that would make life easier. She also became absorbed in the idea of doing something to help the war effort and this was where those long dinners in Germany finally paid off.

After meeting the composer George Anthill, she joined with him in trying to devise a way to prevent the enemy from jamming the radio signals that American ships and planes used to communicate with one another. She and Anthill devised a way to use frequently changing or “hopping” frequencies that would make American messages sound like gibberish to the listening Germans.

The two inventors patented their device in 1942 and Hedy Lamarr offered it to the Navy Department, but it was turned down. We’ll never know why the Navy didn’t recognize the value of the invention, but perhaps it had something to do with the fact that one of the co-inventors was a woman, and a spectacularly beautiful woman at that. How could she possibly know anything about engineering or math?

Whatever the reason, it wasn’t until after the war that the device Lamarr and Anthill invented was used by the military in the Cuban missile crisis of October 1962. Since then it has been used to develop cell phone technology and other electronic devices. All of this happened after the patent had expired, so neither Hedy nor Anthill ever earned a penny from their invention.

In 1997, the Electronic Frontier Foundation presented Hedy Lamarr with a special Pioneer Award and she became the first woman to receive the BULBIE Gnass Spirit of Achievement Award.
