Alexandre Graham Bell citations

Alexander Graham Bell, né le 3 mars 1847 à Édimbourg en Écosse et mort le 2 août 1922 à Beinn Bhreagh au Canada, est un scientifique, un ingénieur et un inventeur scotto-canadien, naturalisé américain en 1882, qui est surtout connu pour l'invention du téléphone, pour laquelle l'antériorité d'Antonio Meucci a depuis été officiellement reconnue le 11 juin 2002 par la Chambre des représentants des États-Unis. Il a été lauréat de la médaille Hughes en 1913.

La mère et la femme d'Alexander Bell étaient sourdes, ce qui a encouragé Bell à consacrer sa vie à apprendre à parler aux sourds. Il était en effet professeur de diction à l'université de Boston et un spécialiste de l'élocution, profession connue aujourd'hui sous les noms de phonologue ou phoniatre. Le père, le grand-père et le frère de Bell se sont joints à son travail sur l'élocution et la parole. Ses recherches sur l'audition et la parole l'ont conduit à construire des appareils auditifs, dont le couronnement fut le premier brevet pour un téléphone en 1876. Toutefois, Bell considéra par la suite son invention la plus connue comme une intrusion dans son travail de scientifique et refusa même d'avoir un téléphone dans son laboratoire.

D'autres inventions marquèrent la vie d'Alexander Graham Bell : les travaux exploratoires en télécommunications optiques, l'hydroptère en aéronautique. En 1888, il devint l'un des membres fondateurs de la National Geographic Society. Wikipedia

Alexandre Graham Bell: Citations en anglais

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

Bell Telephone Talk (1901)
Contexte: 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.

“There cannot be mental atrophy in any person who continues to observe, to remember what he observes, and to seek answers for his unceasing hows and whys about things.”

Statement to a reporter a few months before he died, as quoted at Alexander Graham Bell Family Papers at the Library of Congress http://memory.loc.gov/ammem/bellhtml/bellinvent.html

“Neither the Army nor the Navy is of any protection, or very little protection, against aerial raids.”

As quoted in The Military Quotation Book by James Charlton, p. 37.

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

Bell Telephone Talk (1901)
Contexte: 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.”

Bell Telephone Talk (1901)
Contexte: 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.

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

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.
Contexte: 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.

“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.”

As appears on plaque in the entrance to the Alexander Graham Bell Museum http://www.pc.gc.ca/lhn-nhs/ns/grahambell/index_e.asp in Baddeck, Nova Scotia, Canada.

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

As quoted in "The Chemistry of Life" by Ralph Whiteside Kerr in Rosicrucian Digest (1947), p. 131.
Disputed
Contexte: 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.

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

As quoted in Sophia's Fire (2005) by Sango Mbella, p. 133.

“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.”

Statement to the American Association for the Advancement of Science, in Boston, Massachusetts (27 August 1880): published as "On the Production and Reproduction of Sound by Light" in American Journal of Sciences, Third Series, vol. XX, n°118 (October 1880), pp. 305-324.

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

Quoted in Design of Devices and Systems (1998) by William H. Middendorf, p. 177.
Disputed
Contexte: 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.

“Mr. Watson — Come here — I want to see you.”

First intelligible words spoken over the telephone (10 March 1876), as recorded in Bell's Journal entry (10 March 1876) http://memory.loc.gov/cgi-bin/ampage?collId=magbell&fileName=253/25300201/bellpage.db&recNum=21. These are often misquoted as "Mr. Watson, come here, I want you." Watson later recounted that Bell had spilled battery acid and had called for him over the phone with these words, but this may have been in a separate incident.
