Hedy Lamarr, a Hollywood actress and iconic beauty of the 1940s and 1950s, is often remembered for her stunning looks and captivating on-screen presence. However, few people know that this cinematic siren was also a brilliant inventor, and her groundbreaking work in wireless communication paved the way for the development of modern Wi-Fi technology. In this article, we’ll delve into the fascinating story of how Hedy Lamarr’s pioneering work in spread spectrum technology led to the invention of Wi-Fi, and explore the intriguing details surrounding her remarkable achievement.
The Early Life of a Hollywood Starlet
Born in 1914 in Vienna, Austria, Hedy Lamarr was destined for stardom. With her piercing eyes, raven hair, and striking features, she began her acting career in the 1930s, eventually making her way to Hollywood. Her early films, such as “Ecstasy” (1933) and “Samson and Delilah” (1949), cemented her status as a Hollywood sex symbol, and she became one of the most sought-after actresses of her time.
However, beneath the glamour and glitz of Hollywood, Lamarr had a secret passion: inventing. She was fascinated by the potential of technology to improve people’s lives, and spent countless hours in her trailer, tinkering with gadgets and machines. Her curiosity and creativity eventually led her to develop a revolutionary new technology that would change the face of wireless communication forever.
The Birth of Spread Spectrum Technology
In the early 1940s, Lamarr and her composer friend, George Antheil, began working on a top-secret project: a frequency-hopping system for torpedo guidance. The concept was simple yet ingenious: by rapidly switching between different radio frequencies, a torpedo could be guided to its target without being jammed by enemy signals. This Spread Spectrum technology, as it came to be known, was designed to make radio communication more secure and efficient.
Lamarr and Antheil’s collaboration was an unlikely one. Antheil, a avant-garde composer, brought his knowledge of piano rolls and synchronization to the project, while Lamarr contributed her understanding of wireless communication and her inventive genius. Together, they developed a system that used 88 different frequencies, switched rapidly to avoid interference, and could be used for a wide range of applications, from military communications to radio-controlled torpedoes.
The Patented Innovation
In 1942, Lamarr and Antheil filed a patent for their Spread Spectrum invention, titled “Secret Communication System.” The patent, which was granted in 1942, outlined a system that used a combination of radio frequencies, synchronized with a piano-like mechanism, to transmit signals securely. The patent described the system as follows:
“>The invention relates to secret communication systems, particularly to those in which the signals are transmitted by radio waves, and in which the receiver is adapted to respond only to the particular signals transmitted by the sender.”
The patent was groundbreaking, but it would take decades for the technology to be fully appreciated and developed. During World War II, the US Navy ignored Lamarr’s invention, deeming it too complex for practical use. It wasn’t until the 1950s and 1960s, when the US military began to recognize the importance of secure wireless communication, that Lamarr’s Spread Spectrum technology began to gain traction.
The Evolution of Wi-Fi
In the 1980s, a team of engineers at the Institute of Electrical and Electronics Engineers (IEEE) began developing a new standard for wireless communication. They drew inspiration from Lamarr’s Spread Spectrum technology, adapting it to create a frequency-hopping system that could be used for wireless local area networks (WLANs). The result was Wi-Fi, a technology that would revolutionize the way we communicate and access information.
The IEEE’s 802.11 standard, published in 1997, formally established Wi-Fi as a global standard for wireless communication. The technology used a variant of Lamarr’s Spread Spectrum system, combined with other innovations, to enable rapid and secure data transmission over short distances. Today, Wi-Fi is an essential part of modern life, used by billions of people around the world to connect to the internet, communicate with others, and access a vast array of online services.
The Legacy of Hedy Lamarr
Hedy Lamarr’s contribution to the development of Wi-Fi is undeniable. Her pioneering work in Spread Spectrum technology paved the way for the creation of modern wireless communication systems, including Wi-Fi. Yet, until recently, her role in this achievement was largely unknown.
In 2017, a documentary titled “Bombshell: The Hedy Lamarr Story” shed light on Lamarr’s remarkable life and achievements, including her invention of Spread Spectrum technology. The film sparked a renewed interest in Lamarr’s legacy, and her story has inspired countless women and girls to pursue careers in science, technology, engineering, and mathematics (STEM).
A Tribute to a Trailblazer
Hedy Lamarr’s life was a testament to her boundless creativity, determination, and innovative spirit. From her early days as a Hollywood starlet to her later years as an inventor and philanthropist, she remained a true pioneer, always pushing the boundaries of what was possible.
As we reflect on her remarkable achievements, we are reminded of the importance of recognizing and celebrating the contributions of women in STEM. Hedy Lamarr’s story serves as a powerful inspiration, encouraging us to explore the untapped potential that lies within each of us.

Who was Hedy Lamarr?
Hedy Lamarr was an Austrian-born Hollywood actress who was active from the 1930s to the 1950s. She was known for her stunning beauty and iconic film roles, earning her the nickname “the most beautiful woman in the world.” However, few people knew that Lamarr was not only a talented actress but also a brilliant inventor.
Lamarr’s contributions to the world of technology are often overlooked, but she was a pioneering figure in the development of wireless communication. Her inventions, particularly her work on frequency hopping, paved the way for modern technologies such as Wi-Fi, Bluetooth, and GPS. Despite her significant contributions, Lamarr’s work was largely forgotten until recent years, when her legacy as a trailblazing inventor began to gain recognition.
What was Hedy Lamarr’s invention, and how did it work?
Hedy Lamarr’s invention was a frequency-hopping system for torpedo guidance during World War II. The system, which she developed with composer George Antheil, used a series of radio signals that hopped between different frequencies to guide torpedoes to their targets. This innovative technology was designed to prevent enemy jamming of radio signals, making it more difficult for them to intercept and destroy the torpedoes.
The concept of frequency hopping was ahead of its time, and it wasn’t until decades later that the technology was adapted for use in modern wireless communication systems. The basic principle of frequency hopping remains the same today, with devices rapidly switching between different frequencies to transmit data. This technology has enabled the widespread use of wireless devices, from smartphones to laptops, and has revolutionized the way we communicate.
Why did Hedy Lamarr’s invention go unrecognized for so long?
Hedy Lamarr’s invention went unrecognized for many years due to a combination of factors. One reason was that her work was classified by the US Navy, which meant that it was not publicly disclosed until many years later. Additionally, Lamarr’s invention was not widely adopted during her lifetime, and it wasn’t until the 1960s that the technology began to be developed further.
Another factor that contributed to Lamarr’s invention being overlooked was her gender and her status as a Hollywood actress. At the time, women were not commonly recognized as inventors or engineers, and Lamarr’s work was often dismissed as that of a “movie star” dabbling in science. It wasn’t until recent years, with the growing recognition of women’s contributions to STEM fields, that Lamarr’s legacy as an inventor began to gain the recognition it deserved.
