Alexander Graham Bell birthday!
03/03/1847, Edinburgh, Scotland. Alexander Graham Bell was born, hday. The man behind one of the inventions that changed this world!

There's nothing else that influenced our lives, and we probably would have to list Ford, Marconi, Einstein as part of the people who marked the transformations we had in the last 150 years. Bell was 27 years old when he worked out the principle of transmitting speech electrically, and was 29 when his basic telephone patent was granted in 1876.

The patent was issued on March 7, 1876. Three days later, Bell transmitted human speech for the first time. Bell and Watson, in different rooms, were about to try a new type of transmitter that Bell had briefly described in his patent. Then Watson heard Bell's voice saying, "Mr. Watson, come here. I want you!" Bell had upset the acid of a battery over his clothes, but he quickly forgot the accident in his excitement over the success of the new transmitter.

Bell demonstrated his telephones at the Centennial Exposition in Philadelphia in June 1876. One of the judges, the Emperor Dom Pedro of Brazil, was impressed by Bell's instruments. The British scientist Sir William Thomson (later Lord Kelvin) called the telephone "the most wonderful thing in America."

The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for hydroairplanes, and two for a selenium cell.
