Thomas Alva Edison (1847-1931): although Americans have only read books in school for three months in their life, they are diligent in learning and thinking, and have invented more than 1000 achievements, such as electric light, telegraph, phonograph, film and so on. They have become famous inventors and known as "king of invention", It has 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 company and Edison Electric lighting company merged to establish general electric company, which started the dominance of General Electric in the field of electric for a century< Edison was born on February 11, 1847 in the small town of Milan, Ohio 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 seven 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 because of his teacher's "incompetence". From then on, his mother was his "tutor" and decided to teach his son to read and read, and taught him to be honest, love the motherland and love human beings. Because of his mother's good ecation method, he had a strong interest 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
Edison's earliest interest in natural science was in chemistry. When I was 10 years old, I loved chemistry. He collected about 200 bottles, and saved every penny to buy chemicals and put them in bottles. 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 trains, 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. In 1861, the civil war broke out in the United States. Edison, who had just turned 14 years old, bought an old printing press and used the convenience of the train to run a tabloid (weekly), the herald, to convey the war situation and the news along the way. The first weekly was printed on the train. He is a journalist, editor, typesetter, proofreader, printer and distributor. The tabloids were popular, and he gained talent, knowledge and experience from his intense work. He also earned a lot of money to continue his chemical experiments. With the money he earned, he set up a chemical laboratory on the luggage cart. But unfortunately, when he was doing an experiment on the train, the train suddenly bumped, causing a piece of phosphorus to fall on the board and cause combustion. The conctor came to put out the fire and slapped him in the face. He was driven off the train when Edison was only 15 years old Another way is: Unfortunately, once a chemical caught fire, 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 1868, he invented an automatic electric recorder, which was his first invention. Later he invented two new types of telegraph. In 1877, he invented the carbon telephone transmitter, which made the original telephone sound clearer; In addition, he invented the phonograph. People call him "the magician"< In September 1878, Edison began to study electric lights at the age of 31. At that time, the gas lamp had replaced the kerosene lamp, but the flame flickered and proced harmful gas when it was extinguished; Arc lamp has also been invented and used in public places, but it is not suitable for indoor use because of the hissing sound and too bright when burning. At that time, many European and American scientists had been exploring the manufacture of a new stable luminescent body< After studying the arc lamp, Edison announced that he could invent a satisfactory light, but it needed money. At that time, he was already a person with 170 invention patents. His invention brought great profits to capitalists, so a consortium was willing to provide him with financial support. After thousands of failures, in April 1879, he improved the previous rod-shaped and tubular lamp and made a glass ball; On October 21, 1879, he fixed a carbon treated cotton thread in a glass bubble, pumped out air, sealed the mouth, and applied electric current. It glowed, and a new kind of lighting appeared
from 1880 to 1882, Edison designed electric light socket, button, fuse, current cut-off device, electric meter, hanging lamp, main line and branch line system, made the largest generator in the world at that time, built the first power plant in New York, and opened the first civil lighting system. Later, together with George Eastman, he invented the motion picture camera. Edison's three great inventions: phonograph, electric light and power system, film camera, enriched and improved the civilized life of mankind< Edison died on October 18, 1931, at the age of 84. However, so far no one has been able to break his record of 1099 invention patents. People call him the king of invention< The cause of death was uremia. Setting: West Orange, USA; Buried in: West Orange, USA on August 1, 1931, Edison felt unwell. According to the doctor's diagnosis, he suffered from a variety of diseases: chronic nephritis, uremia and diabetes. The medical bulletin published in the New York Times on August 4 said: & quot; Mr. Edison is like a small boat sailing in the dangerous channel. It may pass safely, or it may hit the rocks. On October 13, Edison ran into & quot; Reef;, And fell into a coma. On October 18, 1931, Edison died at the age of 84< When Edison was a child, his family was very poor. At that time, candles and kerosene were very expensive goods, almost all of which had to be imported. Then Edison thought and thought and thought every day, and finally came up with a very good way, because at that time the cheapest was the power supply. So Edison connected the light-emitting device to the power supply and proced the light for lighting to benefit the poor people all over the world
the story of Edison
one snowy night, Edison's mother suddenly fell ill, and his father rushed to the doctor. The doctor said, "your mother has acute appendicitis and needs an operation.". At that time, there was only oil lamp, but no electric lamp. The light of the oil lamp was very dark, and it would be wrong if you were not careful. Edison suddenly thought of a good way, he took out all the oil lamps at home, and then put a mirror behind the oil lamp to let the doctor finish the operation smoothly. The doctor said, "son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to make a night's sun."< 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. 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. The footprints include Stratford, Adrian, Fort Wayne, Indianapolis, Connecticut, Nashville, Tennessee, Memphis, Louisville and Huron< 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 ran into the diligent Mary Stilwell, 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
