The Inventor
inventor of the incandescent lamp:Thomas Alva Edison
He is one of the inventors who made a major contribution to the world thanks to his invention of the incandescent lamp. He was also a businessman who first mass-produced his invention of the light bulb.
he was born in Milan, Ohio on February 11, 1847. His father was Samuel Odgen Edison and his mother was Nacy Mathews. In 1854, his parents moved to Port Huron, Michigan, where he grew up.
As a child Edison only attended school for 3 months. His teacher complained that because he always got low grades, he could not study at school so his mother decided to teach her own child at home.
he was considered a childhood fool,
his mother worked as a teacher. This is done because when at school by his teacher, Edison is considered a student who is often left behind, stupid and he is considered as an untalented student.
Even so his mother believed that he was not a stupid and backward child.That belief made Edison known as one of the greatest inventors in history and remembered by the world forever.
he has great curiosity, even though it's not school, it's not school, Before reaching school age he had dissected the animals because of his great curiosity.Even at the age of 11 years Edison had built a simple chemical laboratory in the basement. A year later he managed to make a telegraph with a primitive model but still functioning.
Trial after experiment is done with hard effort and high patience. Not a few also need a large enough cost - at least for the size of teenagers at that time. But all of this is not a barrier. Edison then worked as a newspaper and candy suitcase on a train majoring in the cities of Port Huron and Detroit. He also built a small laboratory in one of the train cars in order to continue to conduct various experiments or just read literature. Of course he did so with the permission of the railroad company, Grand Trunk Railway.
In 1861, civil war broke out between the northern and southern states. Edison then had the idea of publishing the first newspaper on a train that was useful to meet people's need for information. He bought an old printing press for US$12, and created his own newspaper called the Weekly Herald. His newspaper sells, he also pocketed US$400 in a day.
In his personal life, Edison was married twice. The first was in 1871 with a woman named Mary Stilwell and ended in 1884, and the second was with Mina Miller from 1886 until the end of her life. The founder of General Electric in 1890 was also blessed with 6 children, Marion Estelle Edison (1873-1965), Thomas Alva Edison **. (1876-1935), William Leslie Edison (1878-1937), Madeleine Edison (1888-1979), Charles Edison (1890-1969), and Theodore Miller Edison (1898-1992).
Through the 1920s, Edison's health condition worsened. He died on October 18, 1931 at the age of 84. His name continues to be remembered as the most prolific inventor of his time. There are 1,093 patents to his name. He is also known as a person who contributed to the defense of the American government after researching various things such as detecting aircraft, destroying periscopes with machine guns, detecting submarines, stopping torpedoes with nets, and even making them more difficult, increase the power of torpedoes, camouflage ships, and many others.
