One of the many inventions established by Edison was the tin foil phonograph. When Edison was working on his invention he noticed that the tape of the machine sprang off a noise resembling spoken words when worked at a high speed. The machine had 2 needles in it one was used for recordings and the other for playbacks, the machine plays cylinders rather than disks.
At around the age of 12, Edison started to lose his hearing. What caused this to happen was a train conductor smacked him in the ears when he started a fire in a boxcar whilst doing experiments.
Edison was an inquisitive child but also a poor student as his mind often wandered. Edison was the youngest of 7 siblings. One day when Edison was at school his school teacher screamed at him and said that he was rather addled.
When his mother found out that someone had discovered him as a scientist his mother was very furious and pulled him out of school and she hmoe schooled him instead.
