Wi-Fi has become the half-life of modern people, without Wi-Fi can not access the Internet, everyone is like ants on the hot pot. However, few people know that the "frequency hopping technology" that laid the foundation for Wi-Fi technology originated from American movie star Hedy Lamarr.
If you haven't heard of Hedy Lamarr, you must know Snow White, Disney's short black hair is borrowed from Hedy Lamarr, and the image of Catwoman in DC Comics is also inspired by her.
Heidi Lamarr was born on November 9, 1914 in Vienna, Austria.
Her family conditions allowed her to receive a good education. Her mother was a pianist, which also laid the foundation for her later inventions.
The adolescent Hedy Lamarr was obsessed with self-expression and was obsessed with acting, and at the age of teenagers, despite the opposition of her parents, she even gave up her ongoing communication major and followed theater director Max Reinhart to Berlin, Germany.
In 1932, Hedy Lamarr was invited by Czechoslovak films to play the heroine of " Eczechoslovak " , promising to bring the film to the international market , with the only condition that she appeared naked .
She became the first actress in the world to appear naked, but the film did not improve her acting career, but caused a lot of controversy.
Her first husband was Fritz Mandel, a merchant who supplied arms to the Nazis, and his husband enjoyed the business dividends that Heidi's beauty brought him, but could not tolerate her fame and strictly monitored her.
Finally, Hedy Lamarr resisted, and she escaped her husband's control by drugging her attendant maid. So he smoothly returned to the entertainment industry and entered Hollywood.
Heidi's masterpiece was written by Cecil J. The love film "Overlord Girl" directed by B. Demir, Heidi was once praised by Hollywood as "the most beautiful woman in the world".
Her career in acting isn't all she has, she also loves to invent.
She excelled in mathematics as a student and majored in communications. Her first husband's research into radio-controlled torpedoes and wireless communication jamming technology was not hidden from her, and Heidi was even allowed to sit in and even record when talking to weapons experts about the technology.
In March 1938, the Nazis officially entered Austria, and Heidi distanced herself from her failed marriage and numerous Nazi "friends." By the way, the "military secrets" of Nazi wireless communications were also brought to the allies.
In 1939, Hedy Lamarr met the musician George Antyre, who proposed that the idea of "frequency hopping" could be realized by borrowing the practice of the player piano.
Hedy Lamarr and piano composer George Antheil designed an airplane navigation system. George conceived a pair of paper rolls, placed inside the plane and torpedo, to specify the order of frequency of change. With the help of Heidi and George's research and other scientists, their results were gradually completed and a patent was filed for a "frequency jump" device.
However, this patent was not recognized because she was an actress, and the FBI always questioned Heidi's marriage to Mandel and her association with Hitler and Mussolini before coming to the United States, so in World War II, the Americans never used frequency hopping technology to attack Nazi warships, and persuaded Heidi that since she loved the United States, she should use her pretty face to help the government sell war bonds.
It wasn't until the late 50s that Heidi's invention was widely used in military computer chips.
It was not until 1997, when CDMA-based communication technology began to enter public life, that the scientific community remembered Heidi, who was already 83 years old, and the Electronic Frontier Foundation awarded the "Electronic Frontier Fund-Pioneer Award" for the invention of Hedy Lamarr, the first applicant of this patent 50 years ago.
The award recognized Heidi's contributions to computer communications, and scientists called Heidi the mother of CDMA, but she was no longer able to leave her home.
In her later years, Heidi was not happy, and the failure of many marriages may have traumatized her, and she lived alone in the United States, and was finally found dead in her own bed.
Heidi grew up beautiful, perhaps no longer satisfied with her appearance in her later years, so she was addicted to plastic surgery, but her face was ruined, and later she was addicted to drugs.
Throughout Heidi's life, brave and open to live as she wishes, she is the world's first naked actress, she gave up her studies to study acting because of her obsession with herself, she bravely fought against dissatisfied marriage, she is like a plum blossom, proud of the world, and the world remembers her beauty.
