Chinese Name: Thomas Alva Edison
English Name: Thomas Alva Edison
a world-famous American electrician and inventor, known as the "king of invention in the world", has made more than 1000 inventions in his life. In addition to his invention and contribution in phonograph, electric lamp, telephone, telegraph, film and other fields, he also has many famous creations and insights in mining, construction, chemical instry and other fields. Edison had about 2000 inventions in his life, which made great contributions to the civilization and progress of mankind
Edison was also a great entrepreneur. In 1879, Edison founded "Edison Electric lighting company". In 1880, incandescent lamps went on sale. In 1890, Edison had established its various businesses into Edison General Electric Company. In 1891, Edison's thin filament and high purity blank incandescent bulb were patented. In 1892, Tom was born; Houston incorporated with Edison power lighting to form general electric company. General Electric began to dominate the electric field for a century< Edison was born on February 11, 1847 in Milan, Ohio, a small town in the Midwest of the United States. His father is a descendant of the Dutch, and his mother, a former primary school teacher, is a descendant of the Scots. When Edison was 7 years old, his father lost money in the tile business and moved his family to Fort gratiott, a northern suburb of Huron, Michigan. Soon after he moved here, Edison suffered from scarlet fever, which is believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of reading, he was expelled from school by his teacher as an "imbecile". From then on, his mother was his "tutor.". Because of his mother's good ecation method, he became interested in reading“ He not only read extensively, but also read everything at a glance. At the age of 8, he read the works of Shakespeare and Dickens, the most important playwrights in the British Renaissance, and many important historical books. At the age of 9, he could quickly read difficult books, such as nature and experimental philosophy by Parker. When I was 10 years old, I loved chemistry. At the age of 11, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on the train, traveling between Port Huron and Detroit, Michigan. He sells newspapers while doing fruit and vegetable business. Whenever he has time, he goes to the library to read. He bought an old printing press and began to publish his weekly, the herald, the first of which was printed on the train. With the money he earned, he set up a chemical laboratory on the luggage cart. Unfortunately, once a chemical caught fire and he and his equipment were thrown out of the car. Another time, while Edison was trying to get on a freight train, a conctor grabbed his ears to help him get on. This action led Edison to be deaf for life< In August 1862, Edison rescued a boy who was about to die on the train track with great courage. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison served as the telegrapher of Stratford junction station on the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. Footprints, including Stratford, Adrian, Fort Wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville, Huron and other places< In 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention. This is an automatic voting device. Edison thought the device would speed up the work of Congress, and it would be popular. However, one congressman told him that they had no intention of speeding up the agenda and that sometimes voting slowly was out of political need. From then on, Edison decided not to invent anything that people didn't need< In early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison universal press". He dedicated the press to the manager of a big Wall Street company. He wanted to ask for $5000, but he didn't have the courage to say it. So he asked the manager to give him a price, and the manager gave him $40000<
Edison used the money to build a factory on ward street in Newark, New Jersey, which specializes in manufacturing all kinds of electrical machinery. He works all night. He trained a lot of capable assistants. At the same time, he also ran into the diligent Mary, his first bride in the future. In Newark, he made such inventions as wax paper and mimeograph. From 1872 to 1875, Edison invented the double Telegraph and quadruple telegraph, and helped others build the world's first English typewriter< In the spring of 1876, Edison moved to "Monroe Park" in New Jersey. He built the first "invention factory" here, which "marks the beginning of collective research". In 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented his favorite project, the phonograph. Telephone and Telegraph "is a revolution to expand human sensory function"; Gramophone is one of the three great inventions that changed people's lives. "From the perspective of invention imagination, this is his extremely important invention achievement.". By this time, people called him "the magician of Monroe Park"< When Edison invented the phonograph, he finally made a breakthrough in the research of electric lamp after numerous failures. On October 22, 1879, Edison lit the first electric lamp with wide practical value. In order to extend the life of the filament, he retested, and tried out more than 6000 kinds of fiber materials before finding a new luminous body, Japanese bamboo silk, which lasted for more than 1000 hours, and achieved a rable purpose. In a way, this invention is the highest achievement of Edison's life. Then he created a power supply system that allowed distant lamps to be distributed from a central power station, a major technological achievement
his first discovery in pure science appeared in 1883. When experimenting with electric lamps, he observed what he called the Edison effect: an electric charge in the lighted bulb passes through space from the hot filament to the cold plate. Edison patented the discovery in 1884, but did not study it further. Other scientists used the Edison effect to develop the electronic instry, especially radio and television
Edison tried to do what the phonograph did for the ear for the eye, and the film camera was born here. Using a new Celluloid film invented by George Eastman, he took a series of photos and projected them onto the screen quickly and continuously, creating the illusion of movement. He first experimented with films in the laboratory in 1889 and patented them in 1891. In 1903, his company proced the first feature film "train robbery". Edison did a lot of work for the formation and standardization of the film instry< After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to make procts and promote sales for his various inventions; These companies later merged into Edison General Electric Company, later known as general electric company. Since then, his interest has shifted to fluorimetry, ore crushers, magnetic separation of iron, batteries and railway signaling devices
ring World War I, he developed torpedo mechanisms, flamethrowers and underwater periscopes< On October 21, 1929, on the 50th anniversary of the invention of electric light, people held a grand celebration for Edison. Famous scientists such as Einstein of Germany and Madame Curie of France congratulated him one after another. Unfortunately, at this celebration, when Edison delivered his reply, he suddenly fainted e to excessive excitement. From then on, his health went from bad to worse. On October 18, 1931, the scientist who had made great contributions to mankind died of illness at the age of 84
Edison's ecation level is very low, but his contribution to mankind is so great. What's the "secret" here? In addition to a curious heart, he has an instinct to test himself, that is, he has the infinite energy and bold spirit of extraordinary hard work. When someone called Edison a "genius", he explained: "genius is one percent inspiration and ninety-nine percent perspiration." In the "invention factory", he organized many people of different professions, including more than 100 scientists, engineers, technicians and workers. Many of Edison's major inventions were successful thanks to this collective force. His achievements are mainly e to his hard work and creative ability as well as the collective strength. In addition, his wife also played a very important role< In August 1862, Edison rescued a boy who was about to die on the track of a train. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it.
