Hedy Lamarr: The Hollywood Star Who Had More on Her Mind

Hello lovely,
Imagine being considered one of the most beautiful women in Hollywood, only to find that hardly anyone was interested in what you had to say. That was something that Hedy Lamarr knew rather well. With her dark, beautifully waved hair, striking features and glamorous screen presence, she became one of the most recognisable faces of Hollywood’s Golden Age. Audiences adored her, photographers couldn’t get enough of her, and MGM knew exactly how to market her extraordinary looks.

But while Hollywood was busy making her into a screen goddess, Hedy was spending her spare time working on inventions. And one of those inventions would eventually earn her a place in the National Inventors Hall of Fame.

Her story takes us from the theatres of Vienna to the film studios of Hollywood, with a rather unexpected detour into wartime radio technology. Along the way, there are spectacular costumes, controversial films, difficult marriages and a woman who refused to let other people’s expectations limit her interests.

From Vienna to the Silver Screen

I liked play-acting. I used to do it all the time as a child.

Hedy Lamarr

Hedy Lamarr was born Hedwig Eva Maria Kiesler on 9th November 1914 in Vienna, then part of Austria-Hungary. Her father was a bank director, while her mother was a concert pianist. Growing up in a cultured household, she developed an early interest in performing. But she was curious about how things worked too. According to the accounts of her childhood, she enjoyed taking objects apart and examining their mechanisms, an early indication of the inventive streak that would later become such an important part of her life.

By her teens, Hedy had begun pursuing acting professionally, appearing in European films and theatre productions. In 1933, she attracted international attention with the Czech film Ecstasy. Its nudity and portrayal of female sexual pleasure caused considerable controversy, although the film did help establish her reputation as an actress.

Her personal life was becoming complicated as well. That same year, she married Fritz Mandl, a wealthy Austrian arms manufacturer. Their marriage was unhappy, and Mandl’s business connections brought Hedy into contact with discussions about military technology.

I knew I could never be an actress while I was his wife. He was the absolute monarch in his marriage… I was like a doll.

Hedy Lamarr on her marriage

She eventually left the marriage and travelled to London, where she met MGM studio executive Louis B. Mayer. Mayer offered her a Hollywood contract and a new Hollywood screen name, Hedy Lamarr. The transformation was complete, at least as far as the film industry was concerned.

Hollywood had found its new beauty

Hedy’s American film debut came in Algiers opposite Charles Boyer. Released in 1938, the film established her as a major Hollywood attraction. MGM quickly recognised her appeal. Her European background, sophisticated appearance and mysterious screen persona suited the romantic dramas and elaborate productions that were popular at the time.

She went on to appear in films such as Boom Town (1940), Ziegfeld Girl (1941), Tortilla Flat (1942) and Samson and Delilah (1949). The last of these, directed by Cecil B. DeMille, became one of her best known films. As Delilah, Hedy appeared in lavish costumes and dramatic jewellery, with the sort of extravagant Hollywood styling that still attracts vintage fashion enthusiasts today.

Yet there was a frustration beneath the glamour. Hollywood’s fascination with her appearance often overshadowed her intelligence and other abilities. Hedy herself recognised the problem. In a remark recorded by the Smithsonian, she wrote:

My face has been my misfortune.

It’s a rather sad observation from someone whose beauty had brought her so much professional success.

The Fashion and Beauty of Hedy Lamarr

Of course, we can’t talk about Hedy Lamarr without having a little look at the clothes. Her screen image offers a wonderful introduction to the polished glamour of the late 1930s and 1940s. The clothes were beautifully considered, whether she was photographed in a sharply tailored outfit or wearing an elaborate evening gown. Her publicity photographs show the influence of Hollywood costume design, where every detail was carefully chosen to photograph well.

The clothes

Hedy’s film costumes and studio portraits provide plenty of inspiration for anyone who enjoys vintage fashion. The contrast between structured tailoring and fluid eveningwear is particularly lovely. In some photographs, she wears defined shoulders and fitted waists, while others show softly draped fabrics and decorative necklines.

These styles also reflect wider developments in American fashion. Hollywood designers such as Gilbert Adrian helped popularise strong shoulders, sophisticated tailoring and dramatic eveningwear during this period. The Metropolitan Museum of Art documents Adrian’s influence on both cinema and everyday American fashion, including the way his designs moved from the screen into commercial clothing. It’s worth remembering that a studio portrait or film costume doesn’t necessarily tell us what an actress wore in her everyday life. Hollywood’s publicity departments worked very hard to create these images. Still, there’s plenty to admire.

The hair and makeup

Hedy’s dark, glossy waves became one of her most recognisable features. Her hairstyles frequently featured smooth, sculpted curls, sometimes parted in the centre and sometimes arranged to one side. They beautifully framed her face and suited the carefully lit black and white photography of the period.

Her makeup was similarly polished, with defined brows, emphasised lashes and shaped lips. In surviving photographs, you can see how the combination of hair, makeup, lighting and photography helped create the image of Hollywood sophistication that audiences associated with her.

If you fancy trying a little of that glamour yourself, I’ve already put together a more practical guide to Hedy Lamarr’s vintage hair, makeup and fashion. It covers the details without requiring a Hollywood makeup department.

The inventor behind the Hollywood star

Any girl can be glamorous. All you have to do is stand still and look stupid.

Hedy Lamarr

Now, here’s where Hedy’s story takes a particularly interesting turn. Away from the film sets, she was an enthusiastic inventor. She had no formal engineering qualification, but she enjoyed investigating technical problems and developing possible solutions. During the Second World War, she became interested in how radio controlled torpedoes could be protected from enemy interference. At the time, radio signals could potentially be detected or deliberately jammed, making the technology unreliable in military situations. Hedy believed there might be a way around the problem.

In 1940, she met George Antheil, an avant-garde composer who also had an interest in engineering and mechanical systems. The pair began developing a method of communicating through radio signals that rapidly changed frequencies. Their idea became known as frequency hopping. The principle was that a transmitter and receiver could switch between different radio frequencies in a synchronised pattern. Anyone attempting to interfere with the transmission would have a much harder time identifying and blocking the signal. Antheil’s experience with synchronised player pianos helped inform the proposed mechanical system. The pair submitted their patent application in June 1941, and on 11 August 1942, they were awarded US Patent No. 2,292,387 for a Secret Communication System. A Hollywood actress and an experimental composer had come up with a serious technical proposal for secure communications. Quite the partnership.

Did Hedy Lamarr Invent WiFi?

This is probably the question that brings most people to Hedy’s story, and the answer needs a little explanation. Hedy Lamarr did not invent WiFi itself. She and George Antheil developed and patented an early frequency hopping communication system, a concept that later became important in the development of wireless communication technologies.

Their proposed wartime system wasn’t adopted by the US Navy at the time. However, the underlying principle of spread spectrum communication continued to develop, and frequency hopping eventually became useful in modern wireless technology.

This is why Hedy is frequently associated with technologies such as Bluetooth and WiFi. Her invention belongs to the wider technological history that helped make secure wireless communication possible, although these modern systems were developed through the work of many scientists and engineers over subsequent decades. It’s an important distinction, and one that makes her actual achievement no less impressive.

Why Did Her Invention Go Unrecognised for So Long?

Hedy and Antheil’s invention did not bring them commercial success. Their patent was granted during the Second World War, but the proposed system wasn’t put into practical military use at that time. The technology required further development, and the mechanical implementation presented difficulties. Hedy also continued to be publicly identified primarily as a glamorous film actress rather than an inventor.

During the war, she supported the Allied effort by helping to sell war bonds, while her technical work remained relatively little known. Recognition came much later. In 1997, Hedy and Antheil received a Pioneer Award from the Electronic Frontier Foundation in acknowledgement of their contribution to communications technology. In 2014, Hedy was posthumously inducted into the National Inventors Hall of Fame. She had died on 19 January 2000, aged 85. It’s rather frustrating to think that so much of the recognition arrived towards the end of her life or after her death. But her contribution is now firmly documented in the history of invention.

Life Beyond the Spotlight

Hedy’s personal life was often difficult, despite the glamorous image presented by Hollywood. She married six times, experienced several divorces and faced financial and personal challenges as her film career declined. Her later years were spent largely away from the public eye. There is a temptation to tell her story as though Hollywood simply failed to appreciate a misunderstood genius. The reality is more complicated.

Hedy enjoyed acting and valued her beauty, but she also wanted to explore her intellectual interests. She could be ambitious, inventive, difficult and vulnerable, just like anyone else. Her life contained considerable success, but also disappointment. And perhaps that’s why she remains such a fascinating figure. She doesn’t fit neatly into the tidy version of Hollywood history we’re sometimes presented with.

Why Hedy Lamarr Still Matters

Hedy Lamarr’s legacy is an unusual one. For film enthusiasts, she remains an important figure from Hollywood’s Golden Age, remembered for her performances, striking screen presence and wonderfully glamorous publicity photographs. For vintage fashion lovers, her image offers a beautiful record of late 1930s and 1940s hairstyles, makeup and costume design. And for those interested in science and technology, her work with George Antheil demonstrates how useful ideas can emerge from unexpected places.

I find that last part particularly interesting. Hedy didn’t have a conventional scientific career, but she was curious enough to investigate a problem and determined enough to pursue a solution. She deserves to be remembered for the whole of her life, including the difficult bits, the films, the fabulous clothes and the work she did when the cameras weren’t rolling.
