Alexander Graham Bell è stato un ingegnere, inventore e scienziato statunitense di origine scozzese.

Bell è stato il primo a brevettare un telefono funzionale ed è noto nella cultura popolare e in gran parte della comunità scientifica come l'inventore di tale apparecchio. Altri soggetti a cui è stata attribuita l'invenzione del telefono includono Charles Bourseul, Innocenzo Manzetti, Antonio Meucci, Johann Philipp Reis ed Elisha Gray.

Il padre, il nonno e il fratello di Bell sono stati tutti associati a lavori sull'elocuzione e il linguaggio, e sia sua madre che sua moglie erano sorde, fattori che influenzarono profondamente gli studi di Bell. Le sue ricerche lo portarono a sperimentare dispositivi acustici che culminarono nel primo brevetto per il telefono nel 1876. In retrospettiva, Bell considerò la sua più famosa invenzione un'intrusione nel suo vero lavoro come scienziato e rifiutò di avere un telefono nel suo studio..

Nel corso della sua vita Bell raggiunse molti altri traguardi, tra cui rivoluzionari contributi alle telecomunicazioni ottiche, all'ingegneria degli idroscafi e all'aviazione. Nel 1888 Bell fu uno dei soci fondatori della National Geographic Society. È stato descritto come una delle figure più influenti nella storia dell'umanità..

Frasi Alexander Graham Bell

„I had made up my mind to find that for which I was searching even if it required the remainder of my life.“

—  Alexander Graham Bell
Context: I had made up my mind to find that for which I was searching even if it required the remainder of my life. After innumerable failures I finally uncovered the principle for which I was searching, and I was astounded at its simplicity. I was still more astounded to discover the principle I had revealed not only beneficial in the construction of a mechanical hearing aid but it served as well as means of sending the sound of the voice over a wire. Another discovery which came out of my investigation was the fact that when a man gives his order to produce a definite result and stands by that order it seems to have the effect of giving him what might be termed a second sight which enables him to see right through ordinary problems. What this power is I cannot say; all I know is that it exists and it becomes available only when a man is in that state of mind in which he knows exactly what he wants and is fully determined not to quit until he finds it. As quoted in Making a Habit of Success: How to Make a Habit of Succeeding, How to Win With High Self-Esteem (1999) by MacK R. Douglas, p. 45. Unsourced variant: What this power is, I cannot say. All I know is that it exists... and it becomes available only when you are in that state of mind in which you know exactly what you want...and are fully determined not to quit until you get it.

„You cannot force ideas. Successful ideas are the result of slow growth.“

—  Alexander Graham Bell
Context: You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day, no matter how much study is put upon them.

„Night is a more quiet time to work. It aids thought.“

—  Alexander Graham Bell
Context: I begin my work at about nine or ten o'clock in the evening and continue until four or five in the morning. Night is a more quiet time to work. It aids thought.

„The most successful men in the end are those whose success is the result of steady accretion.“

—  Alexander Graham Bell
Context: The most successful men in the end are those whose success is the result of steady accretion. That intellectuality is more vigorous that has attained its strength gradually. It is the man who carefully advances step by step, with his mind becoming wider and wider — and progressively better able to grasp any theme or situation — persevering in what he knows to be practical, and concentrating his thought upon it, who is bound to succeed in the greatest degree.

„The inventor...looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea. The spirit of invention possesses him, seeking materialization.“

—  Alexander Graham Bell
Context: The inventor... looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea. The spirit of invention possesses him, seeking materialization.

„Don't keep forever on the public road. Leave the beaten track behind occasionally and dive into the woods.“

—  Alexander Graham Bell
Context: Don't keep forever on the public road. Leave the beaten track behind occasionally and dive into the woods. You will be certain to find something you have never seen before, and something worth thinking about to occupy your mind. All really big discoveries are the result of thought. As quoted in "The Chemistry of Life" by Ralph Whiteside Kerr in Rosicrucian Digest (1947), p. 131.

„Don't keep forever on the public road, going only where others have gone.“

—  Alexander Graham Bell
Context: Don't keep forever on the public road, going only where others have gone. Leave the beaten track behind occasionally and dive into the woods. You will be certain to find something you have never seen before, and something worth thinking about to occupy your mind. All really big discoveries are the result of thought. Quoted in Design of Devices and Systems (1998) by William H. Middendorf, p. 177.

„Before anything else, preparation is the key to success.“

„The final result of our researches has widened the class of substances sensitive to light vibrations, until we can propound the fact of such sensitiveness being a general property of all matter.“
