Thomas Edison, the business man who reinvented the world

It is a known fact that Thomas Edison was a great businessman and that he also improved on previous inventions. You would believe that he was the father of the electric age, but it was Nikola Tesla, one of the greatest geeks of all times, who invented alternate current to send electricity far away.

Thomas Edison is known for improving the light bulb, for the phonograph, for improving the battery. He loved chemistry very much and thus he experimented on creating ways to record music and he did this by using was cylinders for his phonograph records. He settled on disc sheets and used polymers coated on a wooden core to build those discs.

The phonographs were the first devices that could replay music recorded on a cylinder or on a disc.
