In 1894 Edison and his assistants invented

Hello, host!

It’s not called an invention, because on April 14, 1894, Edison and his assistants opened the first kinetoscope theater in New York.

About Edison’s various inventions, there is also the following information for reference:

Thomas Alva Edison is a world-famous American electrician and inventor. In addition to his inventions and contributions to the phonograph, electric light, telephone, telegraph, and movies, he also had many famous creations and insights in the fields of mining, construction, and chemical industry. Edison made about 2,000 inventions during his lifetime, making great contributions to human civilization and progress.

Edison was born on February 11, 1847, in the small town of Milan, Ohio, in the midwestern United States. His father is of Dutch descent, and his mother worked as a primary school teacher and is of Scottish descent. When Edison was 7 years old, his father lost money in the roofing business, so the family moved to Fort Gratiot in the northern suburbs of Huron, Michigan. Shortly after moving here, Edison contracted scarlet fever and remained ill for a long time. The disease was believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of studying, he was dismissed by the teacher as an "imbecile" and kicked out of school. From then on, his mother was his "home tutor". Because of his mother's good education methods, he developed a strong interest in reading. "He not only read a lot of books, but he also read ten lines at a glance and could recite them after reading them." When he was 8 years old, he read the works of Shakespeare and Dickens, the most important playwrights of the English Renaissance, and many important historical books. By the age of 9, he could quickly read more difficult books, such as Parker's "Nature and Nature". Experimental Philosophy. I loved chemistry when I was 10 years old. At the age of 11, he experimented with his first telegraph. To earn money to buy chemicals and equipment, he started working. When he was 12 years old, he got a job selling newspapers on a train, traveling between Port Huron and Detroit, Michigan. While selling newspapers, he also runs a fruit and vegetable business. Whenever he has time, he goes to the library to read. He bought an old printing press and started publishing his own weekly magazine, the Herald. The first issue of the magazine was printed on the train. He used the money he earned to build a chemistry laboratory on a luggage cart. Unfortunately there was a chemical fire and he was thrown out of the car along with his equipment. Another time, when Edison was trying to board a freight train, a conductor grabbed his ears to help him get on. This action resulted in Edison becoming permanently deaf.

In August 1862, Edison used fearless heroism to rescue a boy who was about to be killed on the train tracks. The child's father was grateful for this, but since he had no money to repay him, he was willing to teach him telegraph skills. From then on, Edison became involved with this mysterious new world of electricity and embarked on a scientific journey.

In 1863, Edison served as a telegraph operator at the Stratford Junction Station of the Grand Trunk Railway. From 1864 to 1867, he worked as a telegraph operator in various places in the Midwest and lived a wandering life. His footprints include 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 his first invention patent. This is a device that automatically records votes. Edison thought the device would speed up the work of Congress and that it would be welcomed. However, one MP told him that they had no intention of speeding up the agenda and that sometimes voting slowly was politically necessary. From then on, Edison decided not to make any inventions that people didn't need.

In early June 1869, he came to New York to look for work. While he was waiting to be summoned at a broker's office, a telegraph machine broke down. Edison was the only one there who could fix the telegraph, and he got a better job than he expected. In October, he and Pope jointly established a "Pop-Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison Printing Press." He dedicated the printing press to the manager of a large Wall Street company. He wanted to ask for $5,000, but he lacked the courage to say it. So he asked the manager to give him a price, and the manager gave him $40,000.

Edison used the money to build a factory on Ward Street in Newark, New Jersey, specializing in manufacturing various electrical machinery. He worked all night long. He trained many capable assistants, and at the same time, he also happened to meet the diligent Mary, his future first bride. In Newark, he made inventions such as wax paper and mimeograph machines. From 1872 to 1875, Edison invented the double and quadruple telegraph machines, and helped others build the world's first English typewriter.

In the spring of 1876, Edison moved again, this time to "Menlo Park" in New Jersey. Here he built the first "invention factory", which "marked the beginning of collective research." In 1877, Edison improved the telephone invented by Bell earlier and put it into practical use. He also invented one of his pet projects - the phonograph.

The telephone and telegraph "were a revolution that expanded human sensory functions"; the phonograph was one of the three great inventions that changed people's lives. "From the perspective of his inventive imagination, this was his most significant inventive achievement." By this time, he was known as "The Magician of Menlo Park."

While inventing the phonograph, Edison finally made a breakthrough in the research on electric lights after numerous failures. On October 22, 1879, Edison ignited the first electric light with widespread practical value. In order to extend the life of the filament, he tried again and tried more than 6,000 fiber materials before he found a new luminous body - Japanese bamboo filament, which can last for more than 1,000 hours, achieving the purpose of durability. In a way, this invention was the pinnacle achievement of Edison's life. He then created a power supply system that allowed distant lamps to distribute power from a central power station, a major technological achievement.

His first purely scientific discovery appeared in 1883. While experimenting with electric lamps, he observed what he called the Edison effect: a charge inside a lit bulb traveling from a hot filament through space to a cold plate. Edison patented his discovery in 1884 but did not pursue further research. Other scientists used the Edison effect to develop the electronics industry, especially radio and television.

Edison also attempted to do for the eyes what the phonograph had done for the ears, and this is where the movie camera came into being. Using a strip of George Eastman's newly invented celluloid film, he took a series of photographs and projected them onto a screen in rapid succession, creating the illusion of movement. He first experimented with film in the laboratory in 1889 and applied for a patent in 1891. In 1903, his company produced its first feature film, "The Train Robbery." Edison did much to organize and standardize the motion picture industry.

After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to manufacture and market his many inventions; these companies later merged into Edison General Electric Company, later known as General Electric Company. Thereafter, his interests turned to fluoroscopy, ore crushers, magnetic separation of iron, batteries and railway 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, people held a grand celebration for Edison. Famous scientists such as Einstein of Germany and Marie Curie of France congratulated him. . Unfortunately, at this celebration, when Edison was giving a speech, he suddenly fainted due to excessive excitement. From then on, his health deteriorated. On October 18, 1931, this scientist who had made great contributions to mankind died of illness at the age of 84.

Edison’s education level is extremely low, but his contribution to mankind is so huge. What is the “secret” here? In addition to having a curious heart and an instinct for personal experimentation, he also has infinite energy and determination to work hard that are beyond ordinary people. When someone called Edison a "genius", he explained: "Genius is two percent inspiration and ninety-eight percent perspiration." In his "invention factory", he organized people from many different professions There are more than 100 scientists, engineers, technicians, and workers inside. Many of Edison's major inventions relied on the strength of this collective to achieve success. His achievements are mainly due to his hard work, creative talent and collective strength. In addition, his wife also played a very important role.

American inventor. He is famous in history for establishing factory laboratories and pioneering ways to closely integrate technological development and scientific research. Born on February 11, 1847 in Mylan, Ohio, to a Dutch immigrant family. Died on October 18, 1931 in West Orange, New Jersey. He only received 3 months of formal education when he was young. Since the age of 12, he has worked as a newsboy, hawker, and telegraph operator to make a living. Influenced by M. Faraday, he devoted his life to electrical experimental research and invention. In 1868, he invented a vote recorder and tried to sell it to Congress, but it was not adopted. Edison's first invention did not find a market, which made him pay more attention to the practicality of the invention. In 1869, Edison moved to New York from Boston. He improved the telegraph machine of the Golden Indicator Telegraph Company, which was appreciated by the company manager and was employed with a monthly salary of US$300 (which was a very high monthly salary at the time). In 1870, he moved to New Jersey and began his period of efficient invention. The typewriter was improved in 1874. In 1876, a carbon microphone was added to the telephone invented by A.G. Bell to improve the sound of receiving calls.

In 1876, he founded his famous laboratory.

In this laboratory, he broke the tradition of individual scientists conducting research alone, and organized a group of specialized talents (including N. Tesla and others) who proposed topics and assigned tasks to work together on a project. invention, thereby creating the correct way for modern scientific research. In 1877, he invented the phonograph, which made him famous all over the world. In 1878, he began research on incandescent lamps. After many failures in more than ten months, he successfully lit an incandescent carbon filament lamp on October 21, 1879, and it lit up stably for two whole days. In 1882, the world's second public thermal power plant was built on Pearl Street in New York, and the electric lighting system in New York City was established, becoming the prototype of the modern power system. The realization of electric lighting not only greatly improved people's production and labor conditions, but also heralded the coming era of electrification of daily life. In 1883, while experimenting with a vacuum light bulb, Edison accidentally discovered that there was an electric current flowing between the hot and cold electrodes. This phenomenon later became known as the Edison effect and became the basis of the tube and electronics industry. In 1887, he moved to West Orange and in the same year established a larger and more equipped laboratory in the city, the famous Edison Laboratory (later known as the Invention Factory). Here, based on the invention of G. Eastman, his own camera was made. In 1914, the earliest sound film system was made with a phonograph and camera.

In his later years, his inventions and innovations included batteries, cement mixers, recording telephones, duplex and multiplex telegraph systems, railway brakes, etc. During World War I, he served as chairman of the Naval Technical Advisory Committee, directed research on torpedoes and anti-submarine equipment, and invented dozens of weapons. For this, the U.S. government awarded him the Distinguished Service Medal in 1920, and the French government awarded him the Legion of Honor. In 1928, the United States Congress awarded him the Medal of Honor. Throughout his life, Edison and his laboratory were awarded 1,093 invention patents.

Edison invented many inventions in his life, but after all, he lacked systematic scientific knowledge and therefore could not make correct judgments on the development of modern technology. At the end of the 19th century, the AC transmission system had appeared, but he still insisted on DC transmission, and lost the contract to build the Niagara Hydropower Station in the fierce competition with G. Westinghouse; his laboratory blindly trial-produced magnetic mineral separation equipment, consuming After running out of money from the invention of the electric light, he finally had to give up. However, Edison's contributions to the development of electricity, the manufacture of electrical appliances and the promotion of the application of electrical energy have made him one of the greatest inventors in human history.
