ALEXANDER GRAHAM BELL

         Alexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA. His mother was almost entirely¹ deaf, so Alexander became interested in helping² deaf people communicate and in deaf education. This interest led him to invent the microphone. He found that by pressing his lips against his mother's forehead, he could make his mother understand what he was saying.
         He believed that one should always be curious and his most famous saying was:
         "Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never seen before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought."
 It was this exploring around problems and his dynamic spirit that led to his most famous invention - the telephone in 1876. Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. This original telegraph sent a message over distances using Morse code (a series of dots tapped out along a wire in a particular order). But only one message could go at a time. Bell wanted to improve it so that it could send several messages at the same time. He designed a machine that would separate different sound waves and allow different conversations to be held at the same time. But he found the problem difficult to solve. One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass, Bell noticed that when he spoke³ into the ear, the straw drew sound waves on the glass. Suddenly he had a flash of inspiration⁴. If sound waves could be reproduced⁵ in a moving electrical current, they could be sent along a wire. In searching to improve the telegraph,
Bell had invented the first telephone!
          Bell was fully⁶ aware of the importance of his invention and wrote to his father:
          "The day is coming when telegraph wires will be laid on to houses just like water or gas – and friends will talk to each other without leaving home."
           The patent was given in 1876, but it was not until five days later that Bell sent his first telephone message to his assistant Watson. The words have now become famous:
           "Mr Watson - come here - I want to see you."
    Alexander Graham Bell was not a man to rest and he interested himself in many other areas of invention. He experimented with helicopter designs and flying machines. While searching for a kite strong enough to carry a man into the air, Bell experimented putting triangles together and discovered the tetrahedron shape. Being very stable, it has proved invaluable⁷ in the design of bridges.
    Bell was an inventor all his life. He made his first invention at eleven and his last at seventy- five. Although he is most often associated with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybody's life.
