10 Great Inventions by Youngest Inventors of All Times


6. Alexander Graham Bell

(March 3, 1847 – August 2, 1922)
INVENTION: Telephone
AGE: 29

Alexander Bell one of the great youngest inventors was born in Edinburgh, Scotland. He had two brothers, both of whom died of tuberculosis. His father developed a Visible speech system, a set of written symbols, to help the deaf in speaking.


Bell used to be very interested at the possibility of transmitting speech over wires. At the start, Bell’s main interest was in improving telegraph transmission, which could only transmit one message at a time. His harmonic telegraph was based on the idea that several notes could be sent using the same wire if the notes differ in pitch. Between 1873 and 1874, he spent all his time trying to improve the harmonic telegraph. Than eventually he was side tracked by the idea to transmit human voice over wires.

But since he was not a technical person, he found himself an assistant Thomas A. Watson. The two men worked very hard for a year and were successful in sending their first every voice message on March 10, 1876. The famous words were “ Watson – come here – I want to see you”. Bell organized a telephone company in July 9, 1877. When he died in 1922, the whole telephone system was shut down for a minute to give him tribute. Until now, his idea remains to be the number one in the list of great inventions.
