Thomas Edison
Born in Milan (United States) on 11/02/1847; Death in West Orange (United States) on 18/10/1931

Thomas Edison is an American inventor who has filed more than a thousand patents during his career. In particular, it enabled the commercialization of the incandescent electric bulb and contributed to the development of electricity.

Thomas Edison was born in 1847 in a modest family. He is a precocious child, devouring many books and possesses, from the age of 10 years, his small chemistry laboratory. Interested in telegraph and trains, he began in 1866 working as a telegraph operator. In the same year, he invented a duplex telegraph, which became a multiplex in 1869 and which he marketed in the early 1870s to manage stock market prices. With the money raised, he created his own research laboratory in 1874 and filed numerous patents. He invented the phonograph in 1877, recording and reproducing all sounds mechanically.


In 1878, he had the idea of ​​introducing an electrically heated filament into an ampoule to produce light. The concept of the electric light bulb, already invented in 1835 by Lindsay, was taken over by Edison and his team who patented a light bulb in 1879 with a bamboo filament (which holds for only 30 hours). One of his engineers produced in 1881 an incandescent bulb with carbon filament. Thomas Edison, who founded the Edison Electric Light Company in 1879, markets his light bulbs. It is a revolution. In 1882, he founded the first power plant in the world and sought to make electricity accessible to all. The inventor is also the forerunner of the cinema since in 1888 he created the first camera in history, the kinetographer (to record) and the Kinetoscope (to reproduce the images). Thomas Edison continued his research until the end of his life and died in 1831, at the age of 84 years.
