FIVE

One hot afternoon in June, about forty years ago, a young man was

standing in a grimy workshop by the side of a crude little machine

composed of a clock spring reed, a magnet, and a wire. He was bending

over this queer machine listening intently. Suddenly he bent nearer, a

startled look of excitement upon his face. From the clock spring had

come a faint, almost inaudible sound. The young man straightened up

and ran into an adjoining room, where another man stood near a second

instrument similar to the first.

“Snap that reed again!” he cried excitedly.

The assistant obeyed him, and again came that faint twang from the

spring in the front room. The telephone was born!

And the man who accomplished this wonder was a poor young professor of

elocution in Boston, Alexander Graham Bell. He was not an American by

birth. He was born in Edinburgh, Scotland, on March 1, 1847. His father

was Alexander Melville Bell, the inventor of a system by which the deaf

can read speech by observing the motion of the lips.

The Bell family moved to Canada in 1870, and Alexander, the younger,

took up teaching the deaf and dumb in Boston. He became instructor

of phonetics, or the science of articulate sound, in Monroe’s School

of Oratory. He was a hard worker, but poor. One time when he had

rheumatism his employer had to pay his hospital expenses.

It was about this time that Bell began experimenting with the

transmission of sound by electricity. For a number of years other

people had been trying to do this. Sir Charles Wheatstone in England

had discovered that wires charged with electricity often carried noises

in a curious way. In 1869 Reis, a German professor, constructed an

instrument that sent a series of clicks along an electric wire to an

electromagnetic receiver at the other end. And others were turning

their attention to this interesting phase of telegraphy.

But it was Alexander Graham Bell who first succeeded in grasping the

correct idea. A few months after the incident described above, on a day

in January, 1876, he called some of his pupils into a room and showed

them an instrument that transmitted singing from the cellar of the

building to where they were on the fourth floor.

People were at first slow to appreciate the importance of this great

invention: but gradually they came to see its value, and today there

are over seven million telephones in use in the United States alone.

Money and honors have poured in upon the inventor, who still lives

to enjoy his triumph. His income is said to be more than $1,000,000

a year. In 1880 the French government awarded him the Volta prize of

$10,000, and two years later he received from the same country the

ribbon of the Legion of Honor.
