The first female star to appear naked, the most beautiful actress, and the smartest Hollywood female movie star.
These are the names of the Austrian female star Hedy Lamarr.
But these are not the reasons why people continue to remember her many years after her death.
No matter how stunning the face and naked body are, they are short-lived and will eventually be swallowed up by the years and dusted in history.
Her immortality is because while making movies, she invented a wireless communication security technology for the U.S. military in World War II.
The mobile phones and WIFI we use now are inseparable from her invention.
Hollywood porn stars developed military inventions that have been used by future generations to this day. They are really strange people!
Heidi was born on November 9, 1914, in a Jewish banker's family in Vienna, Austria.
My mother is also a Jew and a well-known pianist.
At the age of 12, Heidi won the Vienna Beauty Contest, opening a bright future for herself.
Compared to her stunning beauty, what went unnoticed in her childhood was that her two Jewish parents left her with a very smart IQ.
When she was 4 years old, her father gave her a gold watch, and she asked her father why the watch was spinning in circles and how it did it.
He took apart and reassembled the music box at home, like a boy.
This habit stayed with her even after she became a Hollywood star: In the living room, she set up a special inventor's corner, which contained a drafting table, a lamp and all the necessary drawing tools.
Due to her outstanding appearance, she was noticed by a film studio when she was 15 years old. She dropped out of school and embarked on an acting career. In the following year, she went abroad to Berlin with the producer.
A few years before making the movie, she did not attract public attention.
When she was 19 years old, she boldly appeared naked in the film "Bewitched" and was hailed as a porn star by popular magazines and was highly praised.
She is known as the first actress in film history to appear naked.
The year is 1933.
This year, the Austrian arms tycoon Mandel watched her film and was fascinated by her film. He spent a lot of money to pursue her crazily.
A few months later, the tycoon captured her heart and the two announced their marriage.
Mandel was 14 years older than him. After their marriage, he did not allow her to act in movies again, and he bought back and destroyed all her copies of "Charmed".
In a flash marriage, a crisis of trust is inevitable.
Four years later, Heidi decided to run away from this rich and powerful man because she could not stand her husband's arbitrary behavior and interference in her acting career.
At a banquet, she used hypnotic drugs to charm the maid who was following her and monitoring her, and she jumped out of the window and escaped decisively.
She escaped from Austria by taking a train, came to Paris, France, and finally moved to London, England.
After that, she signed a contract with an American company and broke into Hollywood.
After that, she starred in a series of romance dramas, suspense dramas, thriller dramas and comedies.
With her outstanding Jewish beauty, she was hailed as "the most beautiful woman in the world" by Hollywood.
Because she looks so beautiful, the roles she plays are all sexy beauties and have very few lines, which makes her feel that filmmaking lacks creativity.
As a result, she devoted her interest and energy in innovation and invention in the real world.
The telephone was invented in 1876, and Hertz proved the existence of electromagnetic waves in 1887. A few years later, Armstrong obtained a patent for frequency modulation.
After that, the telephone was quickly used in the military field.
What followed was research on signal confidentiality.
This field was quickly invaded by the Hollywood porn star in the entertainment industry, like a dark horse.
Although Heidi's first husband was annoying to her, she also benefited a lot.
Since her husband never avoided her when he was researching arms and asked her to be his assistant, Heidi learned many courses on advanced weapons from an early age.
For example, she and her husband watched live test videos of torpedo systems.
For example, when she and her husband attended banquets held by weapons experts, or even met with tycoons such as Mussolini, the husband would have his beautiful wife accompany him.
Others use their beautiful wife as a vase, but who knows that this vase is intelligent. With her ears and eyes immersed in it, she discerned the mystery.
She likes research and creation. A few years later, she suddenly had inspiration and overcame a major problem in the US military.
In 1939, after the outbreak of the World War, the Germans and Italians concentrated on researching torpedo technology.
They are all thinking about using radio technology to control to improve the accuracy of torpedoes.
At the same time, the absolute confidentiality of the control process must be ensured.
Torpedo control requires radio signals.
What is the principle of this?
It means that you send out a signal at the operating end here, and there must be a receiving device inside the torpedo that understands what you mean.
In this way, the signal can be sent synchronously and translated simultaneously, so that the instructions can be executed accurately.
The signal is sent on a certain channel. If this frequency is detected by the enemy, it will be easily deciphered and interfere with torpedoes.
How to keep the signal secret?
In August 1940, the National Invention Council of the United States was established. After hearing about it, Heidi volunteered to join.
She told the committee that she knew many weapons development technologies because of information she received from her former husband.
Soon, with her powerful connections, she found Antel, the former inspector of U.S. munitions.
After an in-depth conversation, she told Antel that she was uncomfortable sitting in Hollywood and making a lot of money, but she was very familiar with many new weapons.
In subsequent interactions, she told Antel that she had imagined a radio signal security technology, that is, inventing a frequency that jumps back and forth so that the signal can jump back and forth among several channels. without affecting transmission.
How is this possible?
She said that based on piano principles, this is feasible.
She sat Antheil in front of the piano and asked him to tap on the keyboard. She followed suit on another piano and the sound was exactly the same.
"Look, we are all typing on the keyboard, but it is constantly changing at the same time."
This shows that the signal can jump between different frequencies at will.
In this way, she used piano rolls to control different pianos, thus synchronizing the two pianos.
In other words, the signal that controls the torpedo can also be switched back and forth between different frequencies. As long as the signal settings of the transmitting and receiving devices on both sides are the same, frequency hopping can be performed at the same time to keep the signal clear and correct.
For the enemy, they are monitoring on a fixed frequency, so they will only hear noise continuously.
Heidi also drew a circuit diagram, simulating the 88 keys of a piano for the first time and setting up 88 channels.
This invention was quickly patented.
Unexpectedly, when she presented the patent to the Invention Committee, she was ridiculed:
"Ah, you want to put the piano device into the torpedo? The space is not that big. Son!"
"The most beautiful woman in the movie" should be a spokesperson for war bonds and play a greater role for the country.
…
Sometimes, inherent labels such as beauty can become a stumbling block for you to do something else.
But there is no way, Heidi’s label is too obvious.
Although many years later, people proved that her invention was correct, great and precious, at this time, when she obtained the invention patent and sincerely wanted to contribute to the US military, she was still regarded as Look at it like a porn star.
Therefore, her serious invention will inevitably be regarded as serious nonsense.
After World War II, transistors were used in electronic systems. Against this background, in 1957, American engineers adopted Heidi's design concept.
Later, with her design concept as the core, computer chips were born, and frequency hopping technology began to be widely used.
Satellite systems, wireless Internet transmission, mobile phones, etc. are all inseparable from this basic confidential transmission technology: frequency hopping.
Engineers realized that Heidi Lamarr, the pioneer of this technology, was indispensable, and they all initiated efforts to fight for Heidi's honor.
In 1997, the Electronic Frontier Foundation finally awarded this patent to the first applicant: Hedy Lamarr.
At this time, 55 years have passed since Heidi first proposed a patent and promoted her patent to the US military.
In 1955, she had already faded out of people's sight and became an old woman.
At the award ceremony, her son accepted the award on her behalf.
On the podium, the organizer contacted her. On the other end of the phone, she said tremblingly:
"It's about the time! (This moment has finally arrived. )"
Since then, Hedy Lamarr has been honored as the "Mother of CDMA" and "Mother of WIFI" by scientists. Some people even compared her to Edison, Watt, Bell, etc.
The late honor will always arrive.
This may be the last gift given to Heidi in her life.
More than 2 years later, in January 2000, 86-year-old Heidi passed away.
When she was alive, no one thought she was an inventor. What everyone remembered was her beauty;
After her death, people also used mobile phones and wifi very... Few people know that her greatest legacy to the world is her intelligence.
History will never be forgotten. In 2014, Heidi was inducted into the American Inventors Hall of Fame.
Smart people are not as beautiful as her, and beautiful people are not as smart as her.
