Hedy Lamarr fled Austria and her first husband, Friedrich Mandl, in 1937
Hedy Lamarr, born Hedwig Eva Maria Kiesler in 1914, fled Austria and her first husband, Friedrich Mandl, in 1937. Mandl, an Austrian munitions manufacturer, was reportedly the third richest man in Austria at the time. Lamarr and Mandl married in 1933, but the union was short-lived. Lamarr described her husband as a "tyrant" who prohibited her from pursuing her acting career. She was also forced to play host to Mandl's friends and business partners, some of whom were associated with the Nazi party.
Lamarr secretly fled to Paris and then travelled to London, where she met Louis B. Mayer, who offered her a film contract in Hollywood. To distance herself from her previous identity and the reputation associated with her early film career, she changed her name to Hedy Lamarr, choosing the surname in homage to the silent film star, Barbara La Marr.
In addition to her acting career, Lamarr was also an inventor. During her marriage to Mandl, she gained knowledge about munitions and weaponry, which, combined with her father's influence on her as a child, sparked her interest in technology and inventions. Along with George Antheil, she co-invented a radio guidance system for Allied torpedoes that used spread spectrum and frequency hopping. This technology would later form the basis for modern wireless communication systems, including WiFi, GPS, and Bluetooth.
Lamarr's acting career spanned several decades, and she achieved success in films such as the romantic drama "Algiers" (1938), the Western "Boom Town" (1940), and the religious epic "Samson and Delilah" (1949). She received a star on the Hollywood Walk of Fame in 1960 and was inducted into the National Inventors Hall of Fame in 2014. Lamarr died in 2000, leaving behind a legacy of groundbreaking inventions and a successful film career.

Mandl was reportedly the third-richest man in Austria at the time and had strong ties to fascist governments in Europe
Hedy Lamarr, born Hedwig Eva Maria Kiesler, fled Austria in 1937 to escape her first husband, Friedrich Mandl (also known as Fritz Mandl). Mandl, an Austrian munitions dealer and manufacturer, was reportedly the third-richest man in Austria at the time. He had strong business ties to fascist governments in Europe, including Nazi Germany and Italy.
Mandl's father was Jewish, as was Lamarr's, but this did not prevent him from selling arms to the Nazis. Lamarr wrote in her autobiography that the dictators of Italy and Germany were guests at lavish parties hosted by the Mandl family. Lamarr often accompanied Mandl to business meetings, where she was exposed to discussions on military technology and applied science. This knowledge would later prove beneficial when she co-invented a radio guidance system for Allied torpedoes during World War II.
Lamarr's marriage to Mandl was unhappy and controlling. She described herself as feeling like "a doll" and "some object of art which had to be guarded—and imprisoned—having no mind, no life of its own." Lamarr decided to leave Mandl and her country, fleeing to Paris and then London, where she began her journey toward becoming a film star in Hollywood.
Lamarr's escape from Mandl's grasp was facilitated by her disguising herself as her maid or, by some accounts, wearing all her jewelry to a dinner party and then disappearing afterward. Her departure from Austria and her marriage marked a turning point in her life, allowing her to pursue a career in acting and later inventions.

Lamarr secretly moved to Paris and then travelled to London, where she met Louis B. Mayer, who offered her a film contract in Hollywood
Hedy Lamarr, born Hedwig Eva Maria Kiesler, was an Austrian-born American actress and inventor. She was born in Vienna, Austria, on November 9, 1914, into a wealthy Jewish family. Her father, a bank director, exposed her to the world of technology from a young age, taking her on walks where he explained how different machines worked.
Lamarr began her career in film in the early 1930s, gaining international notice in 1933 with her role in the Czech film "Ecstasy." However, her career was halted by her marriage to Austrian munitions manufacturer Friedrich Mandl (also known as Fritz Mandl) in the same year. Mandl, reportedly the third richest man in Austria at the time, had strong ties to fascist governments in Europe, including Hitler and Mussolini, who attended lavish parties at Lamarr's home. Lamarr became a prisoner in her own home, forbidden by her husband from pursuing her career in film and stage.
In 1937, Lamarr fled from Mandl and secretly moved to Paris. She then travelled to London, where she met Louis B. Mayer, a Hollywood mogul who was seeking émigré talent. Lamarr initially turned down Mayer's offer of a film contract in Hollywood, but she managed to impress him and eventually secured a contract. Mayer persuaded her to change her name to Hedy Lamarr to distance herself from her previous reputation. He brought her to Hollywood in 1938 and promoted her as the "'world's most beautiful woman." Lamarr's performance in the romantic drama "Algiers" (1938) created a national sensation, and she went on to achieve further success with films like "Boom Town" (1940) and "White Cargo" (1942).
In addition to her acting career, Lamarr made significant contributions to the field of technology. During her marriage to Mandl, she gained knowledge about munitions and weaponry through dinner-table conversations with his associates. When she met George Antheil in 1940, they began collaborating on ideas to combat the Axis powers. Together, they invented a radio guidance system for Allied torpedoes that used frequency hopping, also known as "frequency hopping" or "spread spectrum." This technology would later become the basis for modern wireless communication systems, including WiFi, GPS, and Bluetooth.

Lamarr was one of the few European émigrés who escaped Nazi Germany and Austria and became a full-fledged star in another country
Hedy Lamarr, born Hedwig Eva Maria Kiesler, was an Austrian-American actress and inventor. She was born in Vienna, Austria, in 1914, into a wealthy Jewish family. Lamarr's father was a banker, and her mother was a pianist. She began acting at a young age and was fascinated by theatre and film.
In 1933, Lamarr married Fritz Mandl, an Austrian munitions manufacturer with strong ties to fascist governments in Europe, including Nazi Germany. Mandl was reportedly the third richest man in Austria at the time. Lamarr's career was halted by this marriage, as Mandl prohibited her from pursuing her acting career and kept her as a "prisoner in her own home". Lamarr claims that both Hitler and Mussolini attended lavish parties at her home during this time.
Lamarr fled from Mandl and Austria in 1937, escaping to London and then to the United States. She took with her knowledge of munitions and weaponry gained from dinner conversations with Mandl and his associates. In London, she met Louis B. Mayer, who offered her a film contract in Hollywood. Lamarr accepted a $500-a-week contract and changed her name to Hedy Lamarr to distance herself from her previous identity and reputation as "the Ecstasy lady".
In Hollywood, Lamarr became a film star, achieving success with films such as the romantic drama "Algiers" (1938), the Western "Boom Town" (1940), and the drama "White Cargo" (1942). Her most successful film was the religious epic "Samson and Delilah" (1949). Lamarr was honoured with a star on the Hollywood Walk of Fame in 1960.
During World War II, Lamarr, along with composer George Antheil, invented a radio guidance system for Allied torpedoes that used frequency "hopping" to minimise the jamming of radio signals. This invention has been recognised as a key component of modern wireless communication technology, including WiFi, GPS, and Bluetooth.

Lamarr was an Austrian-American actress and inventor who helped develop the technology that forms the basis for today's WiFi, GPS, and Bluetooth communication systems
Hedy Lamarr, born Hedwig Eva Maria Kiesler, was an Austrian-American actress and inventor. She was born in Vienna, Austria, in 1914 and began her film career in Czechoslovakia. Lamarr rose to fame with her performance in the romantic drama "Algiers" in 1938. She achieved further success with films like Boom Town and White Cargo. Lamarr's most successful film was the religious epic "Samson and Delilah" in 1949. She was also a scientist and inventor, co-inventing an early technique for spread spectrum communications, which became the key to many wireless communication technologies used today.
Lamarr fled from her first husband, Friedrich Mandl, an Austrian munitions manufacturer who sold arms to the Nazis, in 1937. She escaped to London and then travelled to the United States, where she began her illustrious Hollywood career.
During World War II, Lamarr, along with her co-inventor George Antheil, developed a radio guidance system for Allied torpedoes that used frequency hopping to prevent detection by the Nazis. This technology laid the foundation for future communication systems, including WiFi, GPS, and Bluetooth.
Lamarr's inventive mind developed this ingenious way of switching between radio frequencies to avoid jamming signals. By manipulating radio frequencies at irregular intervals, their invention formed an unbreakable code, creating a secure communication system. Despite her remarkable contribution, Lamarr did not receive recognition for her invention during her lifetime. It was only in the late 1990s, shortly before her death in 2000, that her inventions gained wider knowledge. Lamarr has rightfully earned the title of "the mother of Wi-Fi".
