Who invented the bulb and when
Before the invention of the electric bulb, people used candles and oil-burning lamps for lighting. These lights could not be used for long and had to be maintained but, the discovery of the bulb changed human life forever. But do you know that this important tool to remove darkness Bulb ka avishkar kisne kiya tha and when? So let us tell, many scientists tried to make it, but in 1879, American scientist and businessman Thomas Alva Edison got complete success.
Edison not only invented the bulb, but he also discovered more than 1000 small and big devices, including – gramophone, motion picture camera, carbon telephone transmitter, alkaline storage battery etc. He was the first person to start 'mass production' in the world. He has patents for the invention of 1093 instruments in America.
Invention of the bulb and interesting facts from the life of Edison
1.) Amazingly, Edison did not learn to speak until he was 4 years old and had a larger than average head size and an unusually wide front.
2.) In 1954, at the age of seven, Edison started going to school and left school in just 12 weeks! The main reason for which was their hyperactivity and lack of attention, due to which even the teachers could not handle them. In the end his mother stopped him from going to school and himself taught him at home till the age of 11.
3.) Edison loved the plays of William Shakespeare and wanted to become an actor. However, he had to drop the idea very soon because of his loud voice and shy nature in front of the audience!
4.) Edison is the only scientist in the world who obtained a patent for some new invention every year for 65 consecutive years (1868-1933).
5.) Thomas Alva Edison had decided that he would not invent any such device which was not in demand in the market and was not sold!
6.) Edison's first invention was a Universal Stock Printer, which he was able to sell along with his other new inventions to General Left, the owner of the Gold and Stock Telegraph Company. An interesting thing related to this is as follows-
Edison felt that the cost of his invention was 5 thousand US dollars and he agreed to sell it for 3 thousand dollars. But Lefts wondered how the $40,000 deal would hold up.
In later years, he told that he had fainted in some way after hearing the proposal of General Left, but still he managed himself somehow and accepted that proposal considering it appropriate.
7.) Early in life Edison worked as a telegraph operator. This work inspired him to make many new devices in the field of telecommunications.
8.) After briefly selling newspapers at the age of 13, Edison decided to start his own newspaper. And started a newspaper called 'Grand Trunk Herald'. He sold this newspaper to his old customers, which he liked very much and he was also successful in this small business.
9.) In 1876, he established his first laboratory in Menlo Park, California, which later became the world's first industrial research laboratory.
10.) Edison made so many world-changing inventions from the laboratory established in Menlo Park that people started calling him 'The Wizard of Menlo Park'.
11.) It took Edison a year and a half to make the world's first electric bulb. When it was burnt, it was burnt for more than 13 hours. Its filament was made from carbonized thread.
12.) On December 31, 1879, the laboratory complex in Menlo Park was illuminated with electric bulbs made by Edison. Thousands of people had gathered to see it for the first time. Interestingly, Albert Einstein was also born in the same year.
13.) Thomas Alva Edison's first invention in the laboratory of Menlo Park was a phonograph made of a thin layer of tin. He was also invited by the White House to demonstrate this invention to the US President - Rutherford Birchard Hayes.
14.) A funny thing about Edison is that he made a device to kill even cockroaches! In which they could easily be killed by using electricity.
15.) Thomas Edison was the first person in the world to play a motion picture on the screen with the help of a motion picture projector on April 23, 1896.
16.) Edison was once experimenting with developing a method for separating ore from stones but he failed in this and had to suffer millions of dollars in losses. He considered it the biggest failure of his life.
17.) By the year 1870, Thomas Edison was counted among the rich people of America. In the same year, he married 16-year-old 'Mary' who worked in his own factory. He had two children from this marriage. They named the two children 'Dot' and 'Dash' in honor of their old Telegraph days.
18.) Unfortunately, his first wife 'Mary' died in 1884 and he married the second 'Mina Miller' in 1886.
19.) After his second marriage, Edison moved to West Orange, a city in the state of New Jersey. Here he built another laboratory for his experiments. The laboratory complex consisted of five buildings. In later years they set up factories around the complex for production. This laboratory and factories were spread on about 25 acres of land which provided employment to about 8000-10000 people.
20.) In his most productive years, Edison worked 18 hours a day.
21.) A terrible fire on December 9, 1914 destroyed most of Edison's factories. But still Edison did not panic about it and decided to raise them again with a new resolution. Within a few months, together with his team, he had rebuilt those factories.
