The Hollywood actress, who is as famous as Edison, once revolutionized torpedo launching technology

On November 9, 1914, a little girl with a golden key was born in Vienna, Austria. Her father was a Jewish banker and her mother was a famous pianist.

The girl was named Hedwig Eva Maria Kiesler, which was really too long, and later she took a more appropriate stage name for herself: Heidi Rama .

Rama is not only beautiful since she was a child, she has learned ballet and piano performance at the age of 7 and can perform on stage, and she has excellent grades in various subjects at the Swedish Girls' School. As a girl, she is also very good at science.

​​Everyone thinks that Rama will develop in this way, and she should first become a high-class socialite, then marry a wealthy businessman and become a lady, and then her husband and son will eventually grow old gracefully.

But that's not the life she wanted, Rama had a dream of becoming an actress as a child.

In 1931, Rama, who was only 17 years old, decisively gave up his communication major and went to Berlin, Germany to study acting with the famous director Max Reinhardt of , Austria at that time.

It is undeniable that Rama, who has been beautiful since she was a child, does have the foundation to be an actress, and her thinking is very avant-garde, and she is willing to pay for her art and dreams.

​​In 1932, Rama starred in a movie called "Crazy Headed", which was released on Czechoslovakia . This movie probably tells the story of the heroine marrying a man who is much older than herself. The difference, the young heroine can't stand the tedious life after marriage, and later escapes the marriage and falls in love with another young man.

In fact, this is not the main point. The point is that in this black and white film in the 1930s, there was basically no dialogue. Rama appeared completely nude. This was also the first time in the history of the film that an actress appeared completely nude. At this time, Rama was only 18 years old.

​​At that time, many countries in Europe announced that the film would be banned, and Rama's father was stunned when he saw the film.

​​In the second year of the film, Rama met her first husband, Austria's third-largest arms dealer. After seeing the movie starring Rama, the wealthy businessman started a crazy pursuit of her.

Arms dealers needless to say, money rights are just as much. Rama's parents are also very supportive of the marriage. In fact, Rama is not worried about finding a rich and powerful husband. The main reason is that Rama's parents think that if their daughter makes such a movie, no one will dare. married woman.

​​Rama then got married in the third month of knowing the wealthy businessman, but what Rama didn't expect was that the wealthy businessman was very possessive and restricted Rama's movements everywhere, not even allowed to go shopping.

​​What's even more incomprehensible is that her husband started to buy back Rama's naked movie "Crazy," because he didn't want others to see his wife naked.

​​The most important thing is that the wealthy businessman often took Rama to the gatherings of high-ranking Nazi officials, because Rama's beauty can satisfy the rich businessman's vanity and bring him more orders.

Rama himself hated the Nazis, and because he was used as a "tool", Rama couldn't bear the marriage.

In 1937, while attending a banquet with her husband, Rama escaped through a hotel bathroom window while using the toilet. He fled to Paris overnight, and a year later came to Hollywood in the United States.

Excellent people will be favored everywhere, Heidi Rama has starred in many movies, and also co-starred with movie stars like Clark Gable , she also broke the break by playing " Cape Wandering Soul " Hollywood The logic that only blond actresses will be popular, and the black-haired Rama will be a hit as long as she starred in the movie.

At this time, the second half of her life began.

Rama's previous husband had been discussing with Nazi officials radio-controlled torpedoes and radio communication jamming technology. This research was originally a military secret, but Rama's husband did not shy away from Rama's audition.

​​Rama, who studied communications, was intrigued by the research and took a lot of notes. She brought this information to the United States with her.

​​At this time, Rama, who was focusing on his acting career, saw an article about the endocrine of human glands in the newspaper. Rama hoped that his body proportion could be adjusted better, so he directly contacted the article Author of George Antares.

​​After the two met, Rama discovered that George's research on glands and was just a hobby. In fact, he was also a Hollywood film scorer and a pianist. The two were quickly attracted to each other and became good friends.

George is also an all-rounder, and he also has a lot of research on radio communication technology, and then the two talked about the U-boats of Nazi Germany at that time.

and the two believed that the torpedo launch technology of the submarine was guided by radio signals to hit the target. If the other party's channel can be detected in advance, it can effectively interfere with the other party's torpedo and make it deviate from the target. Because early radios only used a single channel to transmit, if the other party detected that channel, they could effectively jam the signal.

​​But Rama and Antel think that if a single channel is turned into a multi-channel, each frequency only controls one message, and when launching a torpedo, it can be transmitted through multiple channels of information. When it arrives, it is impossible to find the correct frequency, so as to achieve the effect of anti-interference.

​​Antel also believes that this technology can be combined with the theory of the automatic piano. The automatic piano is also played through pre-coded punched paper. Each hole controls a sound, and the combination can become a song.

​​designed a patent drawing based on this theory. In 1941, the two officially named this technology "frequency modulation technology" and applied for a patent.

In 1942, Rama wanted to donate the patent to the US government free of charge to fight against Nazi Germany, but Rama, who gave a speech on the technical principle at the joint meeting, was laughed at by the officers present.

​​Because this technology is too advanced, people in the military did not understand what Rama was talking about, thinking that the piano and torpedoes spoken by the actress were fooling the US military.

​​is not only that, FBI people also began to question Rama's identity, because his ex-husband has been doing arms deals with the German Nazis, and Rama will be an "undercover" sent by Germany.

The military eventually sealed the patent.

​​Rama saw that he could not persuade the US government, so he used another method to support the anti-fascist struggle. She started a campaign to sell "War Bonds" by auctioning off "Heidi · Mara" kisses, hoping to sell 680 kisses for $17 million against the German Nazis. What

didn't expect was that Rama raised $25 million on one tour, which was in the 1940s, or roughly $350 million today.

to After the end of World War II , the US government gave Rama's patented technology to the Hoffman Radio Company at that time, and the name of the patent inventor has been erased. On the basis of this patent,

Hoffman completed the research and development of the "frequency modulation technology" device. Later, the US military began to use unmanned remote control aircraft in the Vietnam War , which was also based on this technology.

​​includes Qualcomm, the world's top 500 company with a market value of more than 100 billion US dollars. Their core technology is also the CDMA wireless digital communication system, and the theoretical source of this technology is the patent of Rama and Antel. Dave Mock, a well-known engineer in the

​​communications industry, also said: "As long as you have used a mobile phone,It is necessary for you to know and thank her, this sexy female star has made unparalleled contributions to the global wireless communication . "

​​In 2000, Rama passed away peacefully at the age of 86 at home.

In 2014, Heidi Rama was inducted into the American Inventors Hall of Fame, and she was the only actress to be inducted.

Rama's life responded to a word he said : "Movies are often limited to a certain region or a certain era, while technology is eternal. "

To this day Heidi Lamarr is still called "the mother of mobile phones" and even "the mother of Wi-Fi".

In this face-seeing era, "beautiful vases" are everywhere, but those who are full of unknown things Girls who are curious and dare to try new things are truly charming.
