In 19, the word ——Television first appeared. The birth of television is one of the greatest events in the 2th century, and history will remember the name of its inventor-a 14-year-old American boy named Philo T.Farnsworth. Farnsworth was born in a farmhouse in Utah, USA on August 19th, 196. Farnsworth showed signs of early wisdom when he was young. He has photographic memory and natural understanding of any mechanical device he has ever seen. Philo Farnsworth studied in a small school near his farm. He did well in school. He asked his teacher to give him special help in science. The teacher began to help Philo learn a lot of scientific knowledge, which was incomprehensible to most primary school students.

Farnsworth's parents keep moving to find an ideal land to live in. When they settled in Idaho, 11-year-old Ferro was ecstatic when he learned that his new home had power lines. He found bundles of old magazines on science and technology in the attic of his home, and began to teach himself and decided to be an inventor. He soon started experimenting with electricity. He built an engine by himself at the age of 12, and then he built the first electric washing machine for his family.

As early as 192s, when Baird was addicted to mechanical manufacturing methods, in 1921, a 14-year-old boy who was farming potato fields in his hometown was preoccupied with a difficult problem: how to design a novel radio so that it could transmit moving pictures and sounds together? Farnsworth began to seriously consider developing television. He almost instinctively realized that it was not feasible to transmit images by mechanical devices. The young man also has an intuition that the research of electronics, a field of physics that makes him feel novel, may hold the answer to this problem. In any case, electrons can move at a speed unmatched by mechanical devices, which makes the image much clearer and means that there is no need for moving parts. He reasoned that if a picture can be converted into an electronic stream, it can spread in space like a radio wave, and finally it can be reassembled into an image by the receiver. This is a fairly simple idea in essence, but no one seems to have thought of such a simple idea. Philo Farnsworth must solve several problems before he can develop a TV system. One problem is that he is only 14 years old and he knows that no one will listen to a child. In fact, experts say that at that time, only a dozen scientists in the world could understand his ideas. Another problem is that he has no money to realize his idea. One night, Philo saw an article in a magazine about the idea of transmitting images and sounds in the air. Anyone can receive this kind of electronic information by using a certain device, and then they can watch these images. The article said that some of the greatest scientists in the world are working hard for this idea, and these scientists are trying to make a device that can transmit images by using special machinery. This article caused Philo to think. The 14-year-old Philo confirmed that these famous scientists were wrong. He thought that such a machine was impossible to operate, and the speed of this machine could never be fast enough to clearly capture and reproduce electronic signals transmitted through the air. Philo believes that such a device must be electronic, not mechanical. Philo knows that the transmission speed of such electronic devices must be very fast. All he has to do is how to develop such an electronic device. Soon, Philo came up with the idea of developing a receiver: capturing light in a container and transmitting it with a wire. Philo called this "light in a bottle". A few days later, Philo talked to his teacher about a device that could capture images. He drew up a plan and gave it to his teacher. Philo's plan seems simple, but it still clearly conveys the message that a TV set needs to be developed. In fact, all TV sets today still use Philo's early ideas. Philo's teacher is Justin Durman. Many years later, Philo said that Mr. Durman guided him to imagine and opened the door to science for him. His idea of developing a TV system will have to wait. After graduating from high school for two years, Philo entered Brigham Young University in Utah, but he didn't finish his college studies. After his father died, he had to leave school. Philo didn't give up the idea of developing TV sets. A few years later, when he moved to San Francisco, California, he began to work hard to realize his idea. At that time, he was 21 years old. History will remember the name of its inventor-Philo T.Farnsworth.

before Farnsworth, the British scientist John Logie Baird (1888 ~ 1946) had been devoted to the transmission of TV images by mechanical scanning. On October 2, 1925, he finally made the first mechanical TV set that could transmit images, which was the embryonic form of TV. Although the puppet's face is blurred and noisy, it still attracts people's great interest to see vivid images in an inconspicuous black box. The new TV is called "Magic Box". On September 7, 1927, Philo started a device, which was the first working TV receiver. In another room, it was the world's first TV camera. At the beginning of this year, Philo invented this special image tube. The picture presented by the TV receiver is not very clear, but the machine works and TV is invented. In the following months, Philo has found that several people are willing to invest in his invention. Baird is a representative who advocates the development of TV by mechanical scanning. In 1928, the first color TV set was developed, and in 193, his system began to broadcast audio TV programs, which made people feel like they were there, and made the old fable that "a scholar can know what's going on in the world without going out" come true. Therefore, Baird is called "the father of television". He died in 1946.

when the U.S. patent office finally decided that Farnsworth should be the holder of all major patents on television, it was already in the late 193s, which was too late for Farnsworth, and his funds were almost exhausted. With the approach of World War II, the federal government soon announced that it would suspend the development of the television industry. In this way, it had to be postponed until 1946, when the patent of Farnsworth had exceeded the protection period. In August 193, the American government awarded Philo patent certificates, which protected his invention from being copied by others. However, before long, several inventors claimed that they had invented the television device. Among these inventors, one was Ferati Mill Sforokin, who worked for the powerful American Broadcasting Corporation (RCA). RCA began to use legal means to compete with Philo Farnsworth for the right to television invention. It is said that Mr. Sforokin invented the television in the 192s. The powerful ABC claims that it, not the small Philo Farnsworth Television Company, has the right to produce, develop and sell TV sets.

The lawsuit between ABC and Farnsworth TV Company lasted for several years. ABC has proved that Mr. Sforokin has made a TV set, but there is no valid evidence that this TV set has ever worked. At the same time, ABC also claimed that Mr. Farnsworth invented his TV picture tube after Mr. Sforokin invented it. When Farnsworth said that he had this idea a long time ago, ABC said that it was almost impossible for a fourteen-year-old child to have the idea of developing a TV set. The representative of the company also said that Mr. Farnsworth might not even be a scientist. He never graduated from college. ABC said Philo Farnsworth must provide evidence that he invented the TV picture tube. Philo can't provide such evidence, but his teacher can. In the court, Justin Durman came up with a plan made by Philo when he was a student a few years ago. At this time, ABC's legal experts knew that their lawsuit had lost, Philo Farnsworth won the lawsuit, and he had the right to invent TV. However, he has no funds to develop his TV industry. It was not until the 195s that television had an important influence on American life. The names of ABC's presidents, Vratimir Sforokin and David Chanove, are associated with this new industry. However, the manufacturers who were interested in making TV sets at that time seemed to be only interested in mechanical TVs that were destined to be eliminated. Almost no one appreciated Farnsworth's invention, with the exception of American Radio Corporation. This company hired Russian immigrant Zorkin in 193. At that time, Zorkin had made a prototype, the principle was similar to that invented by Farnsworth in 1927, but the imaging effect was not good, with only 4 ~ 5 lines per frame. Zorkin went to San Francisco to visit Farnsworth, who claimed to be a researcher interested in television. Farnsworth had no idea that Zorin was an "industrial spy". Zorin Jinhua spent three days watching in Farnsworth's laboratory, got the most confidential part of the invention, and then returned to the American radio company. Three years later, he made a TV and began to advertise. Farnsworth was in a hurry at this moment, and quickly sought cooperation from big companies in the industry. But at that time, most electronic factories produced radios and had to use the patents of American radio companies. They didn't want to get into trouble. Farnsworth and investors have no choice but to sue American Radio Company to the US Patent Office. The invention turned into a protracted legal battle. Farnsworth's TV patent was obtained in 1927. Although the laboratory of American Radio Company only made TV in 1933, the company argued that a patent of image technology obtained by Zorkin in 1923 was the embryonic form of TV, while Farnsworth produced earlier evidence. Tolman, his teacher, testified that Farnsworth conceived the principle of television as early as when he was in middle school, and he also drew a sketch of Farnsworth's conception in court. In 1934, the United States Patent Office ruled that the television patent belonged to Farnsworth. The American Radio Company refused to accept the appeal, and the appeal lawsuit lasted for another 16 months. The company lost again, but it still refused to admit defeat. Various small lawsuits dragged on for several years. The entanglement of American Radio Company just responded to a famous saying of the company at that time: "We only charge royalties and never pay royalties." When Farnsworth finally legally owned all the major patents on television, it was in the late 193s. It was too late for Farnsworth, and his funds were almost exhausted. With the approach of World War II, the American government soon announced that it would suspend the development of TV industry. As a result, the legal production of television had to be postponed until after 1946, when Farnsworth's patent had exceeded the protection period. As soon as the patent period expired, American Radio Corporation began to mass-produce TV sets, and in the overwhelming public relations activities, it promoted Zorkin and the company's boss as the father of TV. Farnsworth couldn't fight back any longer. He sold his last property to the international telephone and telegraph company, and returned to his hometown in a gloomy mood. He was depressed, lived on alcohol anesthesia, had poor health and was bedridden for several months.

Since then, the name farnsworth has completely disappeared from people's sight. The only time he appeared on a national television program in the United States was in 1957. At that time, as a mysterious guest, he participated in a game program called "I know a secret" on CBS. In the program, the guests present could ask all kinds of questions to the guests, and finally guess the names of the guests to win. Unfortunately, the guests didn't guess who he was, and farnsworth, as the winner, got a prize of $8. Among the questions, one question is: "Have you invented something that will be painful to use?" Farnsworth replied, "Yes, sometimes it is very painful." In his later years, Farnsworth fiercely criticized TV as an invention that wasted people's time, and even once banned children from watching TV. But just like pain, occasionally he can find happiness from TV. In July, 1969, Farnsworth and his wife, elma, were watching TV at their home in Maine. The screen was showing the first human step on the surface of the moon. He said quietly to his wife, "You know, it's all worth it for today."

Farnsworth died of pneumonia in June 1971. The New York Times called him one of the greatest and most charming inventors in the world in his obituary. Since then, rigorous experts in the history of science and technology have determined that Farnsworth invented television on September 7, 1927. In 1983, the United States Postal Service issued a commemorative stamp for him in recognition of his contribution to the development of human society. Time magazine listed him among the 1 greatest scientists and thinkers of the 2th century. Philo Farnsworth died in March 1971. Today, a statue of him is located in the US Capitol. He is one of the most important inventors in the 2th century.
