Thomas Edison and his inventions
The lack of education did not allow Thomas Edison to carry out mathematical and technical expertise of his developments and his constructive solutions relied almost exclusively on his own intuition.
So, continuing to work on the improvement of the telegraph, in 1877, Edison made one of his most famous discoveries — the phonograph — when he developed a system for recording telegraph messages.
A public demonstration of a new recording device made Edison world famous.
This was only the first of his discoveries, which fundamentally changed the second half of the XIX century - Edison designed the incandescent lamp, a movie camera prototype, and a film projector.
In 1887, he opened his own laboratory in West Orange, where, with several dozens of employees, he continued to work on new devices - a power station, an alkaline battery, an electric railway, and so on.
