Grade 8




On March 3, 1847,
Alexander Graham Bell
was born in Edinburgh.
He was a Scotsman although later he
emigrated, first to Canada and then to The
USA in the 1870s.




In America, he worked with deaf-mutes at
Boston University. Soon, Bell started
experimenting with ways of transmitting

speech over a long distance. This led to the
invention of telephone.




Bell and his assistant,
Thomas Watson, conducted
many experiments and
finally came up with a device
which they first introduced in 1876.
Bell said on the phone: “Mr. Watson, come
here. I want you.” This was the first
telephone message.




Traveling all over America,
Bell demonstrated his
invention to the public
countless exhibitions,
and by 1877 the first
telephone was in commercial use.
