Alexander Graham Bell was born in Britain in 1847 in edinburgh ,scotland.Bell had a background of studying about sound and was a teacher for the deaf.The teacher used Visible Speech to help teach the kids how to speak .Visible Speech,which his father invented to help Eliza,his deaf wife ,is made up of pictures of a mouth moving in different ways.In 1875 Bell moved toBoston and took on Mr Watson to help him on the telephone.Mr Watson was very smart,and he was a good person to have around.Mr Watson worked on the transmitter day and night,and was very good at it.Bell worked on the receiver and almost every other day ther would check it together.His first sentence was,"Mr Watson,come here ,i want to see you.''It took forty weeks to get the telephone to carry the sound of human talk.The telephone used a transmitter,receiver and wires.
When they finally made a telephone successfully in1876,Bell wanted to show it to the public.He brought it to the PhiladelphiaCentennial Exposition where the scientists thought it was a silly instrument and only gave him a little corner of the buiding.When the scientists finally came tohim ,they were very tired from their long day of work.They said that they were too tired to check his telephone and they thought it was stupid anyway.Then a lucky thing happened.Dom Pedro,the Emperor of Brazil who had once visited Bell class,recognised Bell,and said that he was a very smart man.The scientists were very tired,but they said OK.When they looked at it ,they said that it had to be put in a higher place in the building and that he had won!Alexander Graham Bell is best -known for the telephone,and it is very useful to people now.He was a very thoughtful person and he thought about whatever he did.We should be thankful for him.
