1847 ~ 193 1
Thomas Alva Edison, a great inventor, was born in Milan, Ohio on 1847. He has only received three years of formal education, and all his teachers think he is a mentally retarded student!
Edison invented his first invention-electronic voting recorder when he was only 23 years old. There is no market for this kind of instrument. Edison devoted himself to inventing what he thought was easy to enter the market. Shortly after the invention of the tape recorder, Edison invented an improved automatic recorder for stock quotes, which earned 40,000 dollars, which was a huge income at that time. Edison went on to make a series of other inventions and soon gained fame and fortune. Perhaps his most creative invention is the phonograph, and he applied for a patent at 1877. But more importantly to the world, he invented the practical incandescent light bulb in 1879.
Edison was not the first person to invent the electric light device. As early as a few years ago, Paris used solitary lights to illuminate the streets. However, Edison's light bulb, together with the transmission device he invented, enabled ordinary families to use electricity for lighting. 1882, his company began to produce household electricity in new york, and since then, household electricity has spread all over the world.
Edison established the first transmission company to transmit electricity to private homes, which laid the foundation for the development of a huge industry. Today, after all, it's not just electric lights that use this power supply, but a whole series of household appliances from TV sets to washing machines. Because the electricity in the transmission network established by Edison is easy to use, it greatly promotes the application of electricity in industry.
Edison made great contributions to the development of movies, cameras and projectors. He is interested in telephones (his carbon microphone greatly improves his hearing), telegrams and typing?

One of the reasons why Edison's work efficiency is so amazing is that early in his career, he set up a research laboratory in Menlo Park, New Jersey, and hired a group of talented assistants to help him with his work. Since then, many industrial companies have established large-scale research laboratories, the prototype of which is Edison's laboratory. Edison's modern and well-equipped research laboratory, where many people work together as a whole, is one of his most important inventions, although he will certainly not get a patent for this invention.
Edison was not only an inventor, but also engaged in manufacturing, and established several companies, the most important of which later became General Electric Company.
Although Edison did not have the temperament of a pure theoretical scientist, he made an important scientific discovery. In 1882, he found that in a state close to vacuum, current can pass between wires that are not in contact with each other. This phenomenon is called Edison effect, which not only has great theoretical significance, but also has important practical application, and finally leads to the establishment of vacuum tube and electronic industry.
Edison suffered from severe deafness for most of his life, but his efforts and perseverance completely made up for this defect. Edison was married twice.
His first wife died when she was young. Both wives gave birth to three children. He died in Orange, New Jersey in 193 1.
It is recognized that Edison is a genius, the greatest invention genius ever. Looking at his practical inventions, a sense of awe arises spontaneously, although most of them may have been made by others within thirty years. But if we look at his inventions separately, we will find that none of them are really significant. For example, incandescent lamps, although widely used, are not an irreparable gap in modern life. In fact, fluorescent lamp, an invention made by completely different principles, is also widely used; If there were no incandescent light bulbs at all, our daily life would not be very different from now. Indeed, before the advent of electric light, people generally thought that candles, oil lamps and gas lamps were quite satisfactory light sources.
Of course, the phonograph is a great musical instrument, but people think that it is eclipsed by the changes that radio, television or telephone bring to our daily life. In addition, completely different recording methods, such as tape recorders, have appeared in recent years. If there is no phonograph or tape recorder at all today, it is relatively irrelevant. Many of Edison's patents are reforms of devices that others have invented, and they are quite useful. Although such reform is beneficial, it cannot be considered as significant in the whole historical process.
Although none of Edison's inventions are outstanding, we should remember that he invented not only one, but a thousand. It is for this reason that I ranked Edison ahead of gagel's Mo Marconi and Alexander Graham Bell.

Thomas Alva Edison is a world-famous American electrician and inventor. He is not only famous for his phonograph, electric light and electricity.
Besides inventions and contributions in telephone, telegraph and film, there are also many famous innovations in mining, construction and chemical industry.
Creativity and insight. Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization.
Edison was born in1February, 847 1 1, Milan, Ohio, in the midwest of the United States. Father is Dutch.
Descendants, my mother used to be a primary school teacher. She is a descendant of Scots. When Edison was 7 years old, his father lost money in the tile business.
The family moved to a suburb north of Lake Huron, Michigan, and settled down. Shortly after moving here, Edison suffered from scarlet fever.
He has been ill for a long time because of a fever. It is believed that this disease is the cause of his deafness. Edison went to school at the age of 8, but read only.
After three months' study, the teacher thought the book was an "imbecile" and kicked it out of school. Since then, his mother has been his "tutor"
Teacher. "Thanks to his mother's good educational methods, he took a keen interest in reading." He not only reads widely,
And the ten lines are clear at a glance, have a look. "At the age of eight, he began to read Shakespeare, the most important playwright in the English Renaissance.
Dickens' works and many important historical books. By the age of 9, he could quickly read difficult books, such as Parker's.
Philosophy of nature and experiment. 10 years old, he loved chemistry. At the age of 1 1, he experimented with his first telegram. Buy in order to make money
After buying chemicals and equipment, he began to work. /kloc-When he was 0/2 years old, he got a job selling newspapers on the train and moved to Port Huron.
And Detroit, Michigan. While selling newspapers, he also deals in fruits and vegetables. Whenever he has time, he goes to the library.
Read a book. He bought an old printing press and began to publish his own weekly newspaper, The Herald. The first issue of the weekly newspaper was published on the train.
Printed in the newspaper. With the money he earned, he set up a chemistry laboratory on the baggage car. Unfortunately, once the chemicals catch fire,
He was thrown out of the car with all his equipment. Another time, when Edison tried to board a freight train, a train
The driver grabbed him by the ear and helped him into the car. This action led to Edison's lifelong deafness.
1862 In August, Edison rescued a dying boy on the train track with fearless heroism. children
Zi's father is grateful for this, but he is willing to teach him telegraph technology because he has no money to reward him. From then on, Edison and this
The mysterious electric new world has a relationship and embarked on a scientific journey.
1863, Edison worked as a telecom operator in Stratford Hub Station, the main railway line. From 1864 to 1867
In, I worked as a telegraph operator in all parts of the midwest and lived a life similar to wandering. Footprints include Stratford and Adri.
Ann, fort wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville and Huron.
Wait for a place.
1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first invention patent.
This is a device for automatically recording votes. Edison thought that this device would speed up the work of Congress and would be very popular.
Yes However, a congressman told him that they had no intention of speeding up the agenda, and sometimes they voted slowly because of politics.
The needs of. From then on, Edison decided never to make any inventions that people didn't need.
At the beginning of June 1869, he came to new york to look for a job. While he was waiting to be summoned in the broker's office, a computer.
The telegram is out of order. Edison was the only person there who could repair the telegraph, so he found a better one than he expected.
Work. On June+10, 5438, he and Pop established "Pop-Edison Company", specializing in electrical engineering science.
Instrument. Here, he invented "Edison Universal Printing Machine". He dedicated this printing machine to a big company on Wall Street.
The manager wanted 5000 dollars, but he didn't have the courage to say it. So he asked the manager to give a price, and the manager gave it.
Forty thousand dollars.
Edison used the money to build a factory in Ward Street, Newark, New Jersey, which specializes in manufacturing all kinds of motors.
He worked all night. He trained many capable assistants, and at the same time, he happened to meet diligent Mary, who was the first one in his future.
A bride. In Newark, he invented wax paper and mimeograph. From 1872 to 1875, Edison successively
Invented double and quadruple telegrams, and helped others make the world's first English typewriter.
1in the spring of 876, Edison moved to Menlo Park, New Jersey again. He's here.
The completion of the first "invention factory" marked the beginning of collective research. 1877, Edison improved the early
