Edison is also a great entrepreneur, he was formed in 1890 Edison General Electric Company (Edison General Electric Company), its two main business composed of the big-name General Electric Company (GE).
Biography
Edison was born on February 11, 1847, in Milan, Ohio, a small town in the west-central United States of America. His father was of Dutch descent and his mother, who worked as an elementary school teacher, was of Scottish descent. When Edison was seven years old, his father lost money in the shingle business and moved the family to Fort Gratiot, a northern suburb of Huron, Michigan. Soon after moving here, Edison contracted scarlet fever and was ill for a long time, and it is believed that this disease was the cause of his deafness. Edison went to school at the age of eight, but after only three months of schooling, he was thrown out by his teacher as an "imbecile". From then on, his mother was his "tutor". Because of his mother's good education methods, he has a strong interest in reading. "At the age of 8, he read William Shakespeare, the most important playwright of the English Renaissance, Dickens, and many important history books, and by the age of 9, he could quickly read difficult books, such as Parker's Philosophy of Nature and Experimentation. 10 years old, he had a passion for chemistry. At age 11, he experimented with his first telegram. He began working to earn money to buy chemicals and equipment, and at age 12, he got a job selling newspapers on trains, traveling between Port Huron and Detroit, Michigan. He sold newspapers, had a fruit and vegetable business, and read books in the library whenever he could. He bought an old printing press and began publishing his own weekly newspaper, the Herald, the first issue of which was printed on the train. With the money he earned he set up a chemical laboratory in the baggage car. Unfortunately, on one occasion the chemicals caught fire and he was thrown out of the car with all his equipment. On another occasion, when Edison was trying to board a freight train, a conductor grabbed him by both ears and helped him on board. This action resulted in Edison becoming deaf for life.
In August 1862, Edison saved a boy who was about to be killed on the train tracks with fearless heroism. The boy's father was grateful for this, but with no money to pay him back, was willing to teach him telegraphy. From then on, Edison became involved with this mysterious new world of electricity and embarked on a journey of science.
In 1863, Edison worked as a telecommunication telegraph operator at Stratford Junction station of the Grand Trunk Railway. From 1864 to 1867, he lived a nomadic life as a telegraph operator throughout the Midwest. His travels included Stratford, Adrian, Fort Wayne, Indianapolis, Cincinnati, Connecticut, Nashville, Tennessee, Memphis, Louisville, and Huron.
In 1868, Edison came to Boston (Boston) as a newspaper clerk. That same year, he received his first patent for an invention. It was a device that automatically recorded the number of votes cast. Edison thought the device would speed up the work of Congress and that it would be popular. However, a congressman told him that they had no intention of speeding up the agenda and that there were times when slow voting was politically necessary. From then on, Edison decided that he would never again work on any invention that people didn't need.
In early June 1869, he traveled to New York to look for work. While he was waiting to be summoned at a broker'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, and in October he joined with Pope to form the Pope-Edison Company, which specialized in scientific instruments for electrical engineering. Here he invented the "Edison Universal Press". He offered this printing press to the manager of a large Wall Street company, wanted to ask for 5,000 dollars, but lacked the courage to say it. So he asked the manager to give him a price, and he gave him $40,000 dollars.
Edison used the money to build a factory on Ward Street in Newark, New Jersey, specializing in all kinds of electrical machinery. He worked through the night. He developed many capable assistants, and also met the industrious Mary (Mary Stilwell), his first future bride. In Newark, he made inventions such as waxed paper and the mimeograph, and from 1872 to 1875, Edison invented the two- and four-weight telegraph, and assisted others in getting the world's first English-language typewriter.
In the spring of 1876, Edison moved again, this time to New Jersey (New Jersey) "Monroe Park". Here he built the first "invention factory", which "marked the beginning of collective research". 1877, Edison improved the early invention of the telephone by Bell, and put it into practical use. He also invented one of his beloved projects, the phonograph. The telephone and telegraph "were a revolution in the extension of the functions of the human senses"; the phonograph was one of the three major inventions that changed people's lives, and "from the point of view of the imagination of the invention, it was his most significant inventive achievement." By this time, people were calling him "the magician of Menlo Park".
Edison in the invention of the phonograph at the same time, after countless failures finally made a breakthrough in the study of electric light, October 22, 1879, Edison lit the first really have a wide range of practical value of electric light. In order to extend the life of the filament, he re-examined, about tried more than 6000 kinds of fiber materials, only to find a new luminescent body - Japanese bamboo filament, which can last for more than 1,000 hours, to achieve the purpose of durability. In one respect, this invention was the crowning achievement of Edison's life. Next, he created a power supply system that allowed distant lamps to distribute electricity from a central power station, a major craft achievement.
His first discovery in pure science came in 1883. Experimenting with electric lamps, he observed what he called the Edison effect: a charge traveling from a hot filament through space to a cold plate inside a lit bulb. Edison patented this discovery in 1884, but did not study it further. Instead, scientists next to him used the Edison effect to develop the electronics industry, especially radio and television.
Edison also attempted to do for the eye what the phonograph did for the ear, and the movie camera was born. Using a strip of George Eastman's newly invented celluloid film, he took a series of photographs and projected them rapidly and continuously onto a curtain, creating the illusion of motion. He first experimented with motion pictures in his laboratory in 1889 and applied for a patent in 1891, and in 1903 his company produced its first feature film, "Train Robbery." Edison did much to organize and standardize the film industry.
After Edison moved his laboratory to West Orange in 1887, he founded a number of commercial companies to manufacture and market his many inventions; these companies were later merged into the Edison General Electric Company, later known as General Electric. Thereafter, his interests turned to fluoroscopy, ore mashing machines, magnetic separation of iron, storage batteries, and railroad signaling devices.
During World War I, he developed torpedo mechanisms, flamethrowers and underwater periscopes.
On October 21, 1929, on the 50th anniversary of the invention of the electric light, a great celebration was held for Edison, with famous scientists such as Albert Einstein of the German Bundes*** and States and Madame Curie of the French **** and States congratulating him. Unfortunately, in this celebration, when Edison made a speech, due to excessive excitement, he suddenly fainted. Since then, his health is deteriorating. 1931 October 18, this has made great contributions to mankind's scientists died of illness, aged 84 years.
Edison's culture is very low, the contribution to mankind is so great, here's the "secret" is what? In addition to a curious heart, a personal test instinct, is that he has more than ordinary people's hard work of endless energy and bold spirit. When someone called Edison a "genius", he explained: "Genius is two percent inspiration plus 98 percent sweat." He was in the "invention factory", the organization of many different professional people, including scientists, engineers, technicians, workers *** more than 100 people, Edison's many major inventions is to rely on the collective strength of this success. His achievements are mainly attributed to his hard work and creative talent and the power of the collective, in addition, his wife had also played a fairly important role.

Edison
Curious nature
Edison was a world-famous inventor. He invented about two thousand things in his life, such as phonograph, electric light, movie, storage battery and so on. Edison's contribution to mankind can be great! In the history of the world's scientific development, his name seems to be a bright star, always shining brightly.
February 11, 1847, Edison was born in Milan, Ohio.
When he was a child, his body was thin and weak, and he did not like to speak, he was very quiet, he loved to use his brain, he loved to think about problems, and he was always full of a kind of curiosity about all the things that happened around him. He often sat alone by the crossroads of the village, watching how the big elm tree sprouted green buds, and how the autumn wind dyed the maple leaves red. He also pondered for a long time: why did the sun always rise slowly from the east in the morning and then hide behind the mountains in the west in the evening? Why are there white clouds floating in the blue sky ......
One day, when he was five years old, Edison suddenly disappeared. Dad looked around in a hurry and finally found him squatting in a chicken coop!
"What are you doing here?" Dad asked curiously.
"I'm hatching chicks." Edison answered seriously. It turned out that the day before, he had seen a hen lying on an egg and hatching chicks, so he wanted to try it himself to see if he could hatch chicks.
Dad pulled him up in a good-natured and amused manner and said to him, "Silly boy! You won't be able to hatch chicks! Get out of here!"
Little Edison frowned, unsatisfied, and asked, "Why can't I hatch chicks, but hens can?"
Edison was such a curious child that he wanted to know everything and try everything himself.
On another occasion, he found a wild beehive on the garden fence. Ah, what mysteries were in it? He cautiously probed and looked inside, and it seemed that none of the bees were home. What a great opportunity! I'll see what's in the hive today," he thought. He picked up a stick and poked it inside. This is bad news! A swarm of wild bees flew out of the nest with a "buzz" and swooped down on him. Edison's face swelled up like a loaf of bread, and he dropped the stick and ran.
He often went to the neighboring sawmills, shipyards, where all kinds of tools are particularly interested in, he always love to pester the master worker asked this and that, sometimes asked the other people can not answer, had to say "I do not know". He did not stop, non-chase asked "why you do not know". Edison is such a child.
When Edison was seven years old, his family moved to Port Huron, Michigan. where he went to school.
At that time, only three classes were offered in school: reading, writing, and arithmetic. In the classroom, the teacher gave boring lectures, but often punished students with wooden planks. Edison liked to break the sand pot to ask the end, often asked the teacher open-mouthed, unable to speak. The teacher was furious and often called him a "fool" in public.
Edison could not bear such insults, and returned home in tears, telling his mother about his grievances and saying that he would never enter a school again.
His mother had been a teacher and knew better how to educate. She sympathized with her son's situation and said angrily,
"Teachers can't treat students like this!" She took her son by the hand, found the school, and chided the teacher, saying, "The fact that you can't teach such a student only shows your own incompetence! I'm going to educate him myself and show you what kind of person he can become!" In a fit of rage, mom withdrew Edison from school. From then on, Edison left school.
When he returned home, his mother called him by his nickname and said to him seriously, "Tom, from now on, I will teach you to read, do you have the determination to learn?"
Mom's words y touched Edison's heart. With a rare serious look, he replied, "Mom, don't worry! I will study hard and do something in the world when I grow up!"
Edison was very diligent and studious. He was under the specific guidance and patience of his mother's help, carefully studied English, arithmetic, chemistry, geography, history ...... which most attracted him or chemistry. He tried to find a chemistry book to read, and all the pocket money he had saved to buy instruments and medicines for experiments.
The cellar at home became his "laboratory". On top of his homemade wooden frame, there were more than two hundred bottles containing various medicines. Every day after he finished his classes at his mother's place, he ran into the cellar as fast as he could to do his beloved experiments. This was a most joyous thing for Edison.
One day, Edison looked up and saw birds soaring freely in the sky, and a thought came into his head: if birds can fly, why can't people? Can we come up with a way to let people also fly to the sky? He pondered, suddenly thought: if the human body is filled with gas, not also like a balloon up to the sky? After careful observation, Edison found that there is a kind of medicine powder can produce gas. He was so happy that he went to mobilize his young friend Midgeley to do a test. Edison put a large dose of powder to let Mijili drink, not long ago, Mijili stomach pain in the ground straight rolling, crying loudly, the whole family are alarmed. Mom and Dad asked about the situation, very alarmed, rushed to call the doctor, to save the life of Midgeley. Dad was so angry that he whipped Edison severely with a willow whip. But while Edison was being beaten, he was still thinking in his mind, "It's a shame that Midgeley is halfway through his trial, but he won't put up with it!"
Edison's recklessness, so that the mother was very annoyed, she thought, these chemicals, most of them are poisonous, randomly eaten will be life-threatening, little Tom is too much nonsense! So, she angrily rebuked: "This cellar is not allowed to use you again, also not allowed you to engage in experiments." Edison was so anxious to hear that he cried. He felt that he was doing wrong, and was afraid that his mother really did not let him do experiments, so he begged his mother bitterly, "If I don't do experiments, how can I study and learn? How can I make a career?"
Mom couldn't help but be secretly surprised when she heard her son's words. It turned out that the child's oath, not just say, this is his engraved in the heart of the ambition. Mom withdrew the ban, and Edison's first chemistry lab lived on.
Special lab
Edison was 12 when the newly built railroad from Huron to Detroit opened. Not wanting his mom and dad to add to the cost of his experiments, he decided to go on the train and sell newspapers to earn some money to supplement his family's income.
Edison sold newspapers and read at the same time. He left the house at seven o'clock in the morning and returned home at nine-thirty at night. The train had to stop for a few hours in Detroit, so he used the opportunity to go to the city's largest library and read, rain or shine, without fail.
One day, out of the blue, a gentleman asked him, "I've often seen you in the library; how many books have you read?"
"I've read 15 feet of books."
Hearing this peculiar answer, the gentleman laughed, and asked gravely, "What is the object of your reading, when the book you have just read, and the book you now hold in your hand, are entirely different in content?"
Edison, not understanding the meaning of the question, said, "I read in the order of the shelves, and I want to read all the books in this library, one after the other!"
The gentleman was even more surprised and said, "Gee! Your ambition is great! However, reading books without a purpose and reading everything will not be very effective. I hope you'll choose a goal first, and then work toward that goal before you'll be rewarded."
This chance conversation inspired Edison greatly, and had a very profound guiding significance for his reading, learning and growth.
On the train, Edison had some spare time besides selling newspapers. Unwilling to let the time go by in vain, he asked the old conductor to borrow a corner of the baggage car to do experiments. The old wagonmaster, though grumpy, was kind-hearted. He agreed to the boy's earnest request. Edison was overjoyed, and he brought many chemicals and instruments. So the little baggage car soon became the world's first train laboratory.
Suddenly, disaster struck.
That day, the train was speeding along the uneven track, shaking the cars from side to side. A bottle of white phosphorus was knocked to the ground with a loud bang. White phosphorus is a chemical element, it has two strange temperament: one is easy to oxidize, once encountered in the air and the air in the oxidation of the combination, and immediately heat, so that the temperature continues to rise. Secondly, it has a low ignition point, that is, the temperature at which it can catch fire is very low, about 50 degrees Celsius, and it burns itself. Therefore, when the bottle of white phosphorus was shocked to the ground, immediately on fire, this small laboratory smoke and fire. Seeing the bad situation, Edison hurriedly took off his coat and put out the fire, shouting, "Put out the fire! Put out the fire!"
The old captain and the workers heard the news, could not find out the cause of the fire, rushed to extinguish the fire. After a struggle, the fire was finally extinguished. However, the old wagonmaster was furious, he pulled up his voice, Edison scolded a pass, but also heavily hit him a few slaps. At that time, Edison only felt "buzzing" a moment, his ears can not hear anything. It turned out that his right eardrum was ruptured. The future inventor paid the price of one ear for his favorite experiment.
The unfortunate encounter did not cause Edison to stumble. Unable to conduct his experiments on the train, he planned to return home after selling his newspaper. By this time, his interest had shifted to electricity.
Edison teamed up with a neighbor's kid and installed a simple transceiver. They set up bamboo poles between the two homes, pulled up wire for the wires, and found some glass bottles to use as insulators, and the two kids often practiced from evening until late at night, and sometimes, until early in the morning.
It was a coincidence that soon after the fire, Edison suddenly got a good opportunity to learn about electricity.
One morning in August 1862, Edison was selling newspapers at a small station. When he looked up, he saw a three- or four-year-old boy squatting beside the railroad tracks playing with stones, and a wagon train was speeding toward him. Edison "oops", threw down the newspaper, rushed down the platform, a grabbed the child. At this time, the train whistled past his ear. So close to it! Edison fell to the tracks with the boy in his arms, his face and hands cut, however, the child was saved.
The little boy's father's name was McKenzie, and he was the stationmaster at this station, and he was an excellent telegraph operator. McKenzie saw this thrilling scene with his own eyes and was so moved that he couldn't speak coherently, "Thank ...... you, thank you for saving ...... saving my child!"
Edison, however, smiled unconcernedly, he picked up the newspaper from the ground, patted the dust and dirt on his body, boarded the train and left.
The next day, when the train Edison was traveling on came into the station, McKenzie was already waiting on the platform. He said to Edison with great sincerity, "I have nothing to remunerate you for. I have heard that you are interested in telegraphy, and if you wish, I can teach you the art of sending and receiving telegrams, and make you a telegraph operator." These words spoke right to young Edison's heart. He gladly accepted McKenzie's kind offer and followed him to learn the art of sending and receiving telegrams.
Edison was a dedicated student and made rapid progress. Only three months of work, he sent and received the telegraph technology has been very skillful, McKinsey recommended him to work as a train station telegraph operator, this very unexpected learning opportunity for Edison later carried out the great invention, laid a good foundation.
The quest for learning
In the five years between Edison's 16th and 21st years, he was forced to leave his hometown in search of a career, wandering around, often living in hunger and cold. But as soon as he had a little extra money, he immediately went to buy books and lab supplies.
On one occasion, Edison was working as a night clerk during the day in a city in the southern United States, and he bought dozens of books in an old bookstore, ready to take them home after work.
Early in the morning, three or four o'clock, Edison went home from work. He walked with his head down carrying a heavy bag of books. The police on night patrol saw him from afar with a big bag, walking in a hurry, suspected that it was a thief, shouted at him to stop. But Edison because of deafness, did not hear, still in a hurry. The police mistakenly thought he was trying to escape, raised his gun and let go, until the whistling bullets swept past his ears, he only stood still, and immediately lie down. That's when the police arrived and caught him.
After questioning, the police realized that he was deaf. When he opened the package again, it was full of old books. The policeman said, "Kid, you're lucky! If my shot had been accurate, then you would have given up your life for nothing!"
In the early winter of 1868, Edison was introduced by a friend to the Western Union Telegraph Company in Boston as a telegraph operator. The telegraph service here was very busy, and telegrams often accumulated in large stacks and could not be sent out in a timely manner. Edison thought: If we could send two telegrams at the same time on one line, wouldn't it be twice as efficient? However, he tried it many times without success. Once, he got financial support from Mr. Manager of the company, so he worked day and night on this method of sending double telegrams.
How intense was his life! He slept only four hours a day and spent the rest of his time working. One night he bought a copy of Faraday's Complete Works. As soon as he got off work at night, he read it lovingly, from midnight until the next morning. His friend in the same room asked him, "Aren't you hungry?" Edison looked up, shook his head, and said, "Life is too short, and there are so many things to do, how can I not make every second count!"
Faraday's writings opened Edison's eyes to an extremely rich knowledge of electricity. He once told someone that it was the most instructive book he had ever read. From then on, he was more energetic in his experiments. Finally, when the spring snow had not yet melted, he succeeded in building a double transmitter. Edison's name began to appear in newspapers.
Poor life
One day in 1869, Edison took a steamboat to New York City to try to find a career. He was penniless, and his first breakfast in New York was a begging cup of black tea.
After a day of running around, he finally found a friend, borrowed a dollar, and got a place to rest his head. The friend introduced him to the machine room of the Gold Price Exchange. In the corner of the machine room spread a few burlap sacks. This was Edison's bed.
The exchange had an electric gold price scale machine that automatically displayed the local price of gold at the time. The pivotal part of the machine was in this room. Edison took a keen interest in it, and every day he studied the machine carefully.
Time flew by, and in a flash he had been in New York for three days and had not yet found an occupation. He had to sit quietly in the corner of the machine room every day, watching the movements of the machinery with both eyes.
The financial world of the United States at that time was very chaotic, the rise and fall of the price of gold can directly dominate the city's prices, so the gold price marking machine naturally became the center of attention. Coincidentally, at this juncture, the gold price marker broke down. Reporting the gold price of the communication links cut off. All of a sudden, the crowd tidal wave of people crowded to the front of the exchange, even shouting and cursing, scared the management of the machine technician even where the fault is not known, anxious manager Rouse on the sidelines jumping straight to the feet. At this time, the clever Edison, however, in the side of the calm observation, he has seen where the fault lies, then interjected: "There is a contact spring inside the machine broke and fell into the middle of the two gears."
Laws, hearing that someone had figured out the cause, though he didn't know Edison, hastened to say, "Fit it! Fit it! Hurry!"
Edison quickly disassembled the machine, pressed the spur gears, and took out the broken spring. He worked for two whole hours, and the machine ran normally again.
Laws was so grateful to Edison that he inquired about Edison's origins and immediately gave him a rigorous examination next to a stack of chemistry and physics books. Raus appreciated this young man, found that he not only knows the construction of this machine by heart, but also thought of many ways to improve it. Rouse decided to hire Edison to manage all the technical work of the machine at a salary of $300 per month. Edison was overjoyed because he had never earned so much money before. From then on, he would be able to buy more books and lab supplies. And the job allowed him to further utilize his ingenuity. Later, Edison invented a new type of commercial quotation machine, which paid him 40,000 dollars. Edison was not lured by money to a life of pleasure; he used all the money to open a factory and devoted himself to his inventions.
The inventor's career made Edison work even harder, often day and night. He once told someone, "Sleep is the greatest hindrance to research. People have a death anyway, and when they die they can sleep for a long time, so they don't need to sleep much when they are alive, and they should do more work when they are alive."
