Edison (1847.2.11~1931.18): an American, although he only went to school for a few months when he was a child. Edison likes to play with some strange little experiments at home, and sometimes it is inevitable to make some jokes and make some small mistakes. His father forbade him to do small experiments again. Edison said anxiously, "How can you learn knowledge without doing experiments?" How can we achieve something? "After listening to his words, mom and dad moved to withdraw the" ban ". Through unremitting efforts, he not only made inventions and contributions in the phonograph, electric light, telephone, telegraph and film, but also had many famous creations and opinions in the fields of mining, architecture and chemical industry, and became a famous inventor, known as the "king of invention". Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization. It is said that IQ is 160.

Edison was also a great entrepreneur. 1879, Edison founded "Edison Electric Lighting Company". 1880, incandescent lamps went on sale. 1890, Edison merged its various businesses into Edison General Electric Company. 189 1 year, Edison's thin filament and high vacuum incandescent bulb were patented. 1892, Tom Houston Company and Edison Electric Lighting Company merged to form General Electric Company, which opened the hegemony of General Electric in the electrical field for a century. [Edit this paragraph] Edison 1847+ 1 was born in Milan, Ohio, in the midwest of the United States in February. My father is descended from Dutch, and my mother is a primary school teacher, descended from Scots. When Edison was 7 years old, his father lost money in the tile business, so his family moved to Otterborg, a suburb north of Huron, Michigan. Shortly after moving here, Edison suffered from scarlet fever and was ill for a long time. It is believed that this disease is the cause of his deafness. Edison went to school at the age of eight, but after only three months of study, he was dismissed as an "imbecile" by his teacher and expelled from school (he was ordered to drop out of school for being "stupid"). From then on, his mother was his "mentor" and decided to teach his son to read and write, and to educate him to be honest, love his motherland and love mankind. Because of his mother's good educational methods, he became interested in reading. He not only reads widely, but also reads all kinds of books. At the age of eight, he read the works of Shakespeare and Dickens, the most important playwrights in the English Renaissance, and many important historical books. By the age of nine, he could quickly read difficult books, such as Parker's philosophy of nature and experiment.

Edison's earliest interest in natural science was in chemistry. 10 years old, he loved chemistry. He collected about 200 bottles and saved every penny to buy chemicals and put them in bottles. At the age of 1 1, 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 and traveled between Portron, Michigan and Detroit. While selling newspapers, he also deals in fruits and vegetables. Whenever he is free, he goes to the library to read books. 186 1 year, the American civil war broke out. Edison, who just turned 14 years old, bought an old money printing machine and used the convenience of taking the train to run a tabloid (weekly) Herald to convey the war situation and news along the way. The first issue of this weekly is printed on the train. He is also a journalist, editor, typesetter, proofreader, printer and publisher. The tabloids are very popular, and he also gained talent, knowledge and experience from his intense work, and earned a lot of money to continue his chemical experiments. With the money he earned, he set up a chemistry laboratory on the baggage car. 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 burning. The conductor came to put out the fire and gave him a heavy slap, which made him deaf. He was kicked off the train when Edison was 15 years old. Another way of saying it is: Unfortunately, once a chemical caught fire, he was thrown out of the car with his equipment. Another time, when Edison tried to board a freight train, a conductor grabbed him by the ear and helped him get on the train. This action led to Edison's lifelong deafness. )

Frustration did not discourage Edison. He fell in love with the telegraph again. After repeated research, he invented the automatic power recorder at 1868, which was his first invention. Later, he invented two new types of telegrams. 1877, he invented the carbon telephone transmitter to make the original telephone sound clearer. In addition, he invented the phonograph. People call him a magician.

1878 In September, Edison began to study electric lights when he was 3 1 year old. At that time, the gas lamp had replaced the kerosene lamp, but the flame flickered and when it was extinguished, it would produce harmful gas; Arc lamp has also been invented and used in public places, but it is not suitable for indoor use because it hisses when burning and is too bright. At that time, many European and American scientists were already exploring to make a new and stable luminous body.

Edison studied the arc lamp and announced that he could invent a satisfactory lamp, but he needed money. At that time, he was a man with 170 invention patents, and his inventions brought huge profits to capitalists, so a consortium was willing to provide him with financial assistance. After thousands of failures, in April of 1879, he improved the rod-shaped and tubular lamps of his predecessors and made a glass ball. 1879 65438+1Oct. 2 1 He fixed a carbon-treated cotton thread in a glass bulb, pumped out air, sealed the mouth, applied current to make it glow, and a new lighting object appeared.

From 1880 to 1882, Edison designed light sockets, buttons, fuses, current breakers, electric meters, chandeliers, and also designed main line and branch line systems, making the world's largest generator at that time, establishing the first power plant in new york and opening up the first civil lighting system. Later, he and george eastman invented the movie camera together. Edison's three great inventions: the phonograph, the electric light and power system and the movie camera enriched and improved the civilized life of mankind.

Edison died on 193 1, 10,18 (10,9) at the age of 84. However, so far no one can break his record of holding 1099 invention patents, and people call him the king of invention.
