about Edison

The Birth of the Inventor and the Road to Invention Although Edison's first patented product was not practical, in January 1869, the Telecom News published the news that "Edison became an inventor." Edison left Boston for New York, but could not find his friend at first, so he wandered on the streets for a few days, and finally found him a temporary shelter in the basement of an electrical factory. One night three days later, Edison heard a sudden loud noise from the factory above, so Bagua went up to take a look. It turned out that a large machine was broken. He saw a group of people sweating while working. Immediately, he took the initiative to ask for help. With his knowledge of the machine, he soon discovered that a slingshot had fallen into the middle of the pile of gears and got stuck. The factory director agreed that Edison had some materials, so he offered to hire him with a monthly salary of 300 US dollars. As a technician, his life improved and he got to know another important friend who was also a technician - Franklin. Lianat. Pope (Franklin Leonard Pope), and it is said that this job was strongly recommended by Pope. Not long after, on September 24, 1869, the gold price surged in New York. The company they were working on was acquired by a consortium because it could not support it, so the two decided to start their own business. Opening a joint venture and factory Edison and Bob found several partners to open an electrical company together, specializing in dealing with electrical issues, and the business was good. Many people came to them as consultants along the way, and Edison took care of his customers. While doing his own research, he continued to apply for patents for his inventions. Most of his inventions during this period were used in business, such as gold quotation machines, stock market quotation machines, etc. One time, Edison was helping a factory repair a large machine. When he discovered that he could dismantle the machine and reinstall it, the productivity increased by more than three times. The boss of the factory was overjoyed and asked Edison to turn the machine into a new one. The repair and construction patents were sold to him. Edison thought of asking for three thousand U.S. dollars, but he told the boss that he would give him forty thousand U.S. dollars at the first price. Edison never thought of charging so much money, and had to go to the bank to cash the check and collect cash. At that time, I stuffed some ten and twenty dollar bills into everyone and exposed them. Because of this large amount of capital, in 1871, when Edison was 23 years old, he refinanced a joint venture and opened the first factory with only 18 employees. In the same year, the factory's first The first finished product, the telegraph printing press, was officially launched. This was a machine that could turn telegraph prints into text. With Edison's continuous introduction of inventions, the factory grew stronger. He continued to invent and research, and had obtained 37 patents in 1872, and 35 more in 1873, bringing the number of patents in his hands to more than one hundred and twenty. 2012-01-11 18:26:31 Supplement: The first research institute: In 1876, Edison opened the Menlo Park Laboratory in Menlo Park, New Jersey; Like his family, he often immersed himself in the laboratory doing experiments and making inventions. Because of this, many inventions or improved products at that time were produced here. Not long after the battle for the invention of the telephone began, someone published a "telegraph that knew how to talk", which was the prototype of the telephone. A telecommunications company invited Edison to join the ranks of telephone invention. Later, he and another electrical inventor Alexander. Graham. Alexander Graham Bell published a telephone based on the principle of electromagnetic vibration at about the same time, but due to competition, Bell finally won the right to invent the telephone (later he decided to actually invent the telephone 2012-01-11 18:26 :54 Supplement: More inventions and research In 1880, Edison made the first electric locomotive in the United States. In 1881, Edison moved to New York to continue his research, and opened a school upstairs in the house to teach electrical technology. , Edison opened the first power station in New York. There were new wireless machines, research on improved photographic technology, etc. Edison and his talkies were in the West in 1883. A temporary research institute was opened in West Orange, and the Wenluboga Research Institute was closed in 1884. It was not until 1887 that the West Orange Research Institute was greatly expanded. At this time, the system was officially established and Keep it at home.

In 1889, the 42-year-old Edison invented the "depressing photo" - a silent projector. In 1891, he invented the "Edison beneficiation method" and started operating iron ore, but it lasted eight years

The first research institute: In 1876, Edison opened the Menlo Park Laboratory in Menlo Park, New Jersey; Like his family, he often immersed himself in the laboratory doing experiments and making inventions. Because of this, many inventions or improved products at that time were produced here. Not long after the battle for the invention of the telephone began, someone published a "telegraph that knew how to talk", which was the prototype of the telephone. A telecommunications company invited Edison to join the ranks of telephone invention. Later, he and another electrical inventor Alexander. Graham. Alexander Graham Bell announced a telephone based on the principle of electromagnetic vibration at about the same time. However, due to competition, Bell finally won the right to invent the telephone (it was later determined that the real inventor of the telephone had already been invented by one person). But looking back, the carbon particle vibration transmission device designed by Edison was actually more insightful than the coil vibration transmission device designed by Bell, because Edison's invention was exactly the same as the transmission structure principle of the telephone we later used. Phonograph picture reference: bits.wikimedia/skins-1.18/mon/images/magnify-clip Edison’s first public display of the electric light bulb was on October 21, 1879. At that time, there were already journalists waiting outside the institute. news, and Edison was confident enough to hold an immediate small press conference. A large group of people gathered around the laboratory and talked about it. After Edison called out and turned on the electricity, the lamp bulb using processed cotton wire to make carbon filament shone for a full forty hours. The light was heavier than all the lighting tools that had been used. Many times more violent; starting from this time, electric lights officially replaced the solitary lamp and became a daily lighting tool. However, Edison was still not satisfied, so he continued to look for materials to study ways to improve and extend the burning time of the filament. Finally, he discovered that he could use bamboo chips mixed with coal pellets and asphalt to make a filament. In 1880, Edison finally announced that it could last for 1,000 taels. Electric light bulbs that last for hundreds of hours are cheaper and more durable than light bulbs made of cotton wire. In order to be able to use many, many light bulbs at the same time, Edison worked hard on the invention of generators, plugs, switching systems, and fuses. In 1881, Edison held a light-up event and turned on many groups of light bulbs at the same time. The news immediately caused a sensation around the world. In the same year, he won his first international award at the Paris Exposition. Edison was thirty-four years old at the time. The second wife was married to the first wife Mary. Two years after Edison's death, on February 24, 1886, the 39-year-old Edison met another 19-year-old girl, Mena. He married Mina Miller and also gave birth to three children, namely:

In 1876, he established the first industrial research laboratory in the United States, the "Edison Invention Factory" in Menlo Park. In the next two years, he invented the phonograph, which shocked the world and earned him the title of French knight. Edison's greatest contribution in his life was the invention of the electric light. It took him more than 1,600 experiments with heat-resistant materials and more than 600 plant fibers to create the first light bulb. Later, he continued to improve the manufacturing methods on this basis.

In order to promote the use of electric lights, he developed various additional equipment for electrical systems such as parallel circuits, fuses, insulation materials, and copper wire networks; he also created voltage-stable generators and three-wire switches for economical power distribution. In 1882 he established an electric power grid in New York. Although his use of direct current transmission method limited the distance that power could be transmitted, this great contribution has greatly improved human life. In 1883, Edison discovered the phenomenon of thermionic emission, laying the foundation for the advent of the electron tube. In 1887 he established a larger laboratory in West Orange. There he invented countless more, the more significant of which were the movie camera in 1888; the movie projector and the nickel-iron battery in 1896.
