e. Bell experimented with ways of transmitting speech between deaf - mutes over a long distance
On March 3, 1847, Alexander Graham Bell was born in Edinburgh. He was a Scotsman although he later 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 the 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 telephone: `Mr. Watson, come here. I want you.` This was the first telephone message.
Traveling all over America, Bell demonstrated his invention to the public at countless exhibitions, and by 1877 the first telephone was in commercial use.
