In 1997, when CDMA-based communication technology began to enter public life, the scientific community finally remembered Hedy Lamarr, the founder of the theory of frequency hopping technology. For this reason, the Electronic Frontier Foundation awarded Hedy Lamarr the "Electronic Frontier Fund - Pioneer Award" that year, and the scientific community unanimously called her "the mother of CDMA" and "the mother of WIFI".
In our daily life, WIFI is used by everyone, and the emergence of WIFI has made all families install their own wireless networks, providing great convenience for everyone to access the Internet, but for the inventor of WIFI, people do not seem to be very familiar, so who is the person who invented WIFI? Speaking of this problem, everyone must be speculating whether it is a famous scientist, but the fact is that the person who invented WIFI is a Hollywood actress named Hedy Lamarr.
Hedy Lamarr was born in 1914 in Vienna, Austria, to a wealthy family, the father of a successful banker and a mother of a well-known pianist. As an only daughter, Hedy Lamarr was doted on by her parents, and because of this, she developed a spontaneous and self-serving personality from an early age. In 1930, 16-year-old Hedy Lamarr resolutely gave up the communication major he was studying in order to pursue his artistic dream, despite the strong opposition of his parents, and followed the theater director Max Reinhart to Berlin, Germany to study acting.
Her amazing beauty has also entered people's vision, entering the film studio at the age of 16 in Rama, Haiti, starring in her first movie, and in the camera, because she is the world's first naked actress to be controversial, but everyone has to admit that Hedy Lamarr has amazing beauty, and it cannot prevent Hedy Lamarr from having a very high reputation.
But what many people don't know is that Hedy Lamarr studied communications before entering the entertainment industry, and during World War II in 1940, Hedy Lamarr discussed with his friends about the great maritime power of the German army, while the Allies seemed to be unable to withstand the German offensive. So the thoughtful Hedy Lamarr began to think about what means could stop the German power at sea. Then Heidi Lamarr found his own inspiration on the piano keys, it turned out that Hedy Lamarr when hitting the piano, heard the piano emitted different syllables of high and low length, so he thought of the "frequency conversion blocking" theory, and applied for a patent the following year, although this theory is quite advanced and has strong implementability, but due to the imminent outbreak of war and the limitation of technical strength, this theory was sealed by the military at that time. This seal is more than ten years.
In 1985, Qualcomm was founded in San Diego, a small company that was still unknown at the time, and it was on the basis of "frequency hopping" technology that finally developed the CDMA wireless digital communication system, and thus embarked on a rapid development track. Today, Qualcomm has become a leader in the global communications industry, ranking among the world's top 500 companies, but few people in the world know that the theoretical source of the CDMA wireless digital communication system developed by this company is the long-outdated star Hedy Lamarr.
Hedy Lamarr's scientific work earned him honor half a century later
Fortunately, history has not forgotten Hedy Lamarr. In 1997, when CDMA-based communication technology began to enter public life, the scientific community finally remembered Hedy Lamarr, the founder of the "frequency hopping technology" theory. To this end, the Electronic Frontier Foundation awarded Hedy Lamarr the "Electronic Frontier Fund – Pioneer Award" that year in recognition of her great contributions to the communications industry. Not only that, the scientific community unanimously called Hedy Lamarr "the mother of CDMA" and "the mother of WIFI", and Boeing has issued a series of promotional advertisements to commemorate this technology woman.
In 1958, Hedy Lamarr announced her retirement from filming and switched to becoming the owner, producer and director of a production company, but this experience was quite a failure, and after struggling for 9 years, her production company was finally forced to close. During this period, Hedy Lamarr published a controversial autobiography, which was listed by Playboy magazine as one of the "Top Ten Erotic Autobiographies of All Time" because of the fact that the book described a lot of sexual privacy, and once again attracted endless criticism to Hedy Lamarr.
Heidi Lamarr in old age
In her later years, Heidi began to become depraved, immersed herself in cosmetic surgery and drugs, and was charged several times with theft and rape, and was even arrested and imprisoned at one point. On January 19, 2000, Hedy Lamarr died quietly in her sleep at the age of 86. Although Hedy Lamarr's later years are controversial, she has always been the most beautiful movie star for loyal fans, and she is a respectable technology star for the general public who fully enjoy the convenience of WIFI.
