TEXT

What do the following items have in common: the National Geographic Society the American magazine science, aircraft ailerons, and sheep with lour nipples? No, it's not Trivial Pursuit. All were steered into existence by the same man the inventor of the telephone.

To most people the telephone is one of the greatest inventions of all time. Yet one American newspaper reporter wrote "It is an interesting toy... but it can never he of any practical value."

That reporter was not alone in dismissing the new invention. A British official thought it might prosper in the colonies but not in Britain since "we have an abundance of messenger boys". And the great Western Union Telegraph company rejected an offer to buy the patent. "Bell's profession is that of a voice teacher," they observed. "Yet he claims to have discovered an instrument of great practical value in communication which has been overlooked by thousands of workers who have spent years in the field."

The patent Western Union turned down was one of the most lucrative ever issued, for the commercial success of the telephone was as immediate as it was dramatic. Although Bell at first gave lectures and demonstrations to raise much-needed cash (reserved seats cost 50 cents and the first profit was $i49) the success of the telephone made him and his assistant. Thomas Watson, financially secure by 1881. The telephone was by then a mere five years old.

Western Union did, however, get one thing right in their assessment of Bell: he as indeed a teacher of the deaf.

Born in Edinburgh on March 3.1847, he was christened Alexander. On his eleventh birthday he decided he would like a second Christian name and chose Graham. He and his two brothers inherited a family tradition of teaching elocution. His grandfather had practiced in London and his father was the inventor of a phonetic alphabet called Visible Speech. Both Bell's mother and his wife were deaf Helping deaf people learn to speak became his main career.

Bell received his early education from his mother and he became an accomplished pianist. At ten years of age he started school.

By the time he entered University College, London. At 20, he had taught elocution at Elgin, Edinburgh and Bath.

At university he studied anatomy and biology. But before that in a letter to his father, he had written up his first scientific research, on the resonant pitches of mouth cavities. As a result of this he was introduced to the work of Helmholtz and gained his first knowledge of electricity.

In Quebec, Bell taught his father's Visible Speech to deaf pupils and began to teach teachers of the deaf. In i873 he was appointed professor of vocal physiology at Bteton University. Nine years later he became a US citizen, and very proud of the fact he was too.
