Alexander Graham Bell

Alexander Graham Bell (3 March 1847 - 2 August 1922) was a Scottish scientist, inventor and innovator. Throughout his early life, Alexander Graham Bell was a British subject but in 1915, he characterized his status as: "I am not one of those hyphenated Americans who claim allegiance to two countries." Despite this declaration, Bell has been claimed as a "native son" by Canada, Scotland and the United States. Born and raised in Edinburgh, Scotland, he emigrated to Canada in 1870, and then to the United States in 1871, becoming a U.S. citizen in 1882. Bell would spend his final, and some of his most productive years in residence in both Washington, D.C. and Beinn Bhreagh (Gaelic: beautiful mountain), a summer retreat he built in Nova Scotia, Canada. Recognized as an eminent scientist and inventor, Alexander Graham Bell is most often associated with the invention of the telephone. In later life, Bell considered his most famous invention was an intrusion on his real work and refused to have a telephone in his study.

Bell è stato a lungo tempo considerato come l'inventore del telefono, anche se questo argomento è stato discusso ampiamente, con molte autorità che affermano che fu Antonio Meucci il vero inventore (infatti nel giugno 2002 il parlamento statunitense approvò un documento che attribuiva ufficialmente a Meucci i meriti per l'invenzione del telefono). Altri, poi, sostengono che il merito fu di Elisha Gray, il fondatore della Western Electric Manufacturing Company. Oltre al suo contributo nella tecnologia delle telecomunicazioni, apportò notevoli contributi nella tecnologia dell'aviazione e degli idroscafi.
