Alexander Graham Bell was famous for making the telephone. He was born in the year 1847 in Edinburgh.
His mother was nearly deaf sometimes she tried to listen to Alexander playing the piano although she was nearly deaf.
Before the telephone?
His dad challenged him and his brother to invent something that would be able to make a sound that would make a word. So he and his brother started to make the first telegraph and at the end they made it the telegraph.
Alexander wanted to upgrade the telegraph so he called a man called Watson because he was good at electronics. They tried to make something that would be able to speak from any distance.
They made it but it was not working but then he poured a bit of acid and that was a mistake and it worked and he thanked him.
