Qui saurait de nos jours se passer du fameux téléphone? Nous devons cette merveilleuse invention à Alexandre Graham Bell. Durant cette présentation, nous allons vous parler de ce personnage qui a changé l’histoire de la communication.

Alexandre Graham Bell est né le 3 mars 1847 à Édimbourg en Écosse. Il devient citoyen Canadien en 1882. Il avait deux frères : Melvin James Bell et Edward Charles Bell. Tous deux morts de la tuberculose. À sa naissance, Bell n’avait pas encore de deuxième prénom. Ce n’est qu’à l’âge de 11 ans qu’il fit la demande pour avoir Graham inclus dans son nom. C’était son cadeau d’anniversaire.

Ses parents s’appelaient Alexander Melvin Bell et Eliza Grace. Son père était un professeur de diction.

Durant son enfance, Alexandre collectionnait des espèces botaniques et réalisait déjà ses premières expériences. Encouragé par sa mère, Bell s’intéresse aussi à l’art, la poésie et la musique.

Quand Bell avait douze ans, sa mère commença à perdre graduellement l’audition. C’est pour cette raison qu’il a appris le langage des signes pour pouvoir communiquer avec elle. La surdité de sa mère amène Alexandre à étudier l’acoustique.

À l’école, la science et la biologie étaient ses intérêts principaux. Ses notes, cependant étaient piètres, car il manquait souvent les cours.

Il déménage à Londres pour vivre avec son grand-père après avoir quitté l’école. C’est dans cette période de sa vie qu’il prit goût à l’enseignement. À 16 ans, à Weston House Academy, il fut nommé étudiant-professeur de diction et de musique. Il étudie à l’université d’Oxford, en Angleterre.

Il fut professeur de diction pour les malentendants et c’est ainsi qu’il rencontra Mabel Gardiner Hubbard, son élève. Celle-ci était sourde à cause d’une scarlatine. Ils se marièrent et eurent 4 enfants. Mme. Bell avait aussi des intérêts pour la science et la philanthropie. À partir de 1910, elle milite pour le droit de vote en faveur des femmes avec ses deux filles.

En 1870, Bell et sa famille déménage au Canada. Un an plus tard, il part pour les États-Unis. Là-bas, il fonde une école pour les personnes atteintes de surdité. En 1872, il commence à travailler sur sa future invention révolutionnaire, LE TÉLÉPHONE.

Dès 1874, Bell est certain de pouvoir transformer les ondes sonores en impulsion électrique. C’est le 10 mars 1876 à Boston, au Massachussetts qu’Alexandre Graham Bell réussie à transmettre sa voix à distance pour la première fois.

Au début son appareil s’appelait le vibraphone. Il obtient son brevet dans la même année que son invention. Le vibraphone connaît un immense succès dès sa sortie. Bell passe beaucoup de temps à faire la promotion commerciale de son produit aux États-Unis. Il se fait cependant poursuivre à nombre reprise pour le brevet de son téléphone, mais il gagne à chaque fois. Il devient riche dès 35 ans.

Avec la fortune que lui procure son invention, Bell fonde la national geographic society quelques années plus tard. Il fonde aussi en 1876 la Compagnie de téléphone Bell comme on la connait aujourd’hui.

Lors de l’exposition du centenaire de l’indépendance des États-Unis, à Philadelphie, Bell rencontra l’empereur du Brésil. Dom Pedro 2. Celui-ci était intéressé sur le fonctionnement du téléphone et lui demanda de lui en faire une démonstration. Bell décida de lui réciter un monologue d’Hamlet. Le fameux to be or not to be au téléphone.

Alexandre Graham Bell consacre le reste de sa vie à la science. Que se soit en l’expérimentant lui-même ou en finançant d’autres recherches scientifiques.

Son invention est controversée car il déclare que c’est au Canada qu’il a inventé le téléphone et non aux États-Unis d’Amérique. Il affirme que le téléphone a seulement été fabriqué aux États-Unis.

En 1913, il fut lauréat de la médaille Hughes. Ce prix existe depuis 1902 pour récompenser les grandes découvertes scientifiques.

Ce grand inventeur est décédé le 2 août 1922 à Baddeck, Nouvelle-Écosse à l’âge de 75 ans. Son épouse mourra peu après en 1923.

À la mort de Graham Bell, le Canada et les États-Unis coupèrent les lignes téléphoniques pendant 1 minute à sa mémoire.

En terminant, nous avons choisi Alexandre Graham Bell comme héro canadien, parce qu’il a rendu honneur au Canada et que son invention a changé le cours de l’histoire. Grâce à lui, le domaine de la communication a évolué grandement. Il mérite qu’on connaisse son histoire.

On pourrait le comparer à Reginald Fessenden un Canadien qui a inventé le sondeur sonore et les appareils de transmission sous-marine de signaux. Il eut plus de 500 brevets. Il est né en 1866 dans les Cantons-de-l’Est, dans le compté de Brome. À l’âge de 10 ans, il a même assisté à une conférence de Bell, sur le téléphone en Ontario. Il fut très inspiré par les travaux d’Alexandre et les étudia. Son rêve était de transmettre la voix humaine sans fil. Reginald Fessenden fut malheureusement reconnue pour ses recherches en radiodiffusion que récemment. Il meurt en 1932.

Merci de nous avoir écoutées. J’espère que vous en avez appris un peu plus sur le téléphone et son inventeur. N’oubliez que c’est grâce à lui qu’on peut de nos jours, parler avec nos amis ou avec notre famille même s’ils sont loin de nous. Que ce soit avec un cellulaire ou avec un plus vieil modèle de téléphone.

The Modern Telephone

...22 July 2009 The Modern Telephone In today’s society, instant communication seems to be the norm. I’ve had a cellular phone for the past fifteen years, and cannot see myself without one in the future. It is almost like I cannot live without one.

Telephone Systems

...Week 2 / Individual Assignment Week 2 / Individual Assignment The system used for this paper is one from a previous employer. The system is a ROLM 9751 private branch exchange (PBX) with automatic call distribution (ACD). A major bank uses this system for the Mortgage Banking. Approximately 200 - 500 employees used the system at each site. One aspect of the system is the automatic call distribution group (ACD). An ACD creates a system for the customer service group to take incoming calls. The system also had some unique phone features not available in other systems. The Rolm system also had two T1 trunks, and a tie line trunk group for internal calls from site to site. This system is state of the art, at the time of installation. The downside is the telecommunications group prefers Nortel, so support is not easy. Even though the system is not well supported by telecommunications, the system is a good system because redundancy and integrated ACD. Automatic Call Distribution System An ACD is defined as a computerized phone system that can evenly distribute call to agents [ (ACD Definition from PC Magazine Encyclopedia, 2010) ]. The calls come into the center and hear music until a representative is available or go directly to an available representative. At the time, most ACD systems were not a part of the PBX. They were separate units that are attached to the PBX system. This process worked well most of the time, but the ongoing success rate was not as high...

Telephone Conversation

...Keeping Conversation Flowing Some conversations refuse to flow. Often, this is a result of a clash of the conversational styles of the two people involved. One may be all enthusiasm and sympathy; the other may be quiter and more private. As a result, the other backs off. Another problem is when someone is not interested enough in the other person. A. Improving Your Style Good conversation requires diplomacy and tact. It is give and take. Avoid the following conversation killers: 1. Talking too much. 2. Talking too little. 3. Interrupting. 4. Too much personal disclosure. 5. Going into too much detail. 6. Constantly bringing the conversation back to you. The conversation of most people is all "I", "myself" and "me". Don't fall into this trap. 7. Trying to be funny all the time. 8. Imitating the other person's accent. 9. Being too critical. Being Too Critical Some people are hopeless perfectionists. The standards they demand of life are impossibly high. As a result, most things fall short of their standard and friends stay away from them. Little can be gained from being critical unless: 1. You are criticizing something that can actually be changed. 2. You offer an alternative to the thing you are criticizing. 3. You are specific and clear about what you are criticizing and why. 4. You let others know that what you are saying is only your opinion. 5. You balance your criticism with...

Old and Modern Telephones

...and Livelihood Education II I. INTRODUCTION: Early telephones were technically diverse. Some used a liquid transmitter, some had a metal diaphragm that induced current in an electromagnet wound around a permanent magnet, and some were "dynamic" - their diaphragm vibrated a coil of wire in the field of a permanent magnet or the coil vibrated the diaphragm. The dynamic kind survived in small numbers through the 20th century in military and maritime applications where its ability to create its own electrical power was crucial. The Edison patents kept the Bell monopoly viable into the 20th century, by which time the network was more important than the instrument. Early telephones were locally powered, using either a dynamic transmitter or by the powering of a transmitter with a local battery. One of the jobs of outside plant personnel was to visit each telephone periodically to inspect the battery. During the 20th century, "common battery" operation came to dominate, powered by "talk battery" from the telephone exchange over the same wires that carried the voice signals. By the end of 2009, there were a total of nearly 6 billion mobile and fixed-line subscribers worldwide. This included 1.26 billion fixed-line subscribers and 4.6 billion mobile subscribers. In some countries, many telephone operating companies (commonly abbreviated to telco in American English) are in competition to provide telephone services.

Journal 1: Answering the Telephone

...Journal 1: Answering the Telephone For this project I surveyed and researched the “Telephone Response Violation.” By doing so I would answer my phone and not say a word then I would jot down my observations of the other persons response. However, before I started my violation survey I was really quite worried. It doesn’t matter if you’re in China or America; it’s an impolite behavior to not answer or greet when someone phones you. Perhaps the person calling me might think I accidently hit the wrong button or something, which would potentially lead to them hanging up and redialing me again. I assume if I don’t answer within 5 seconds the person calling me would just hang-up and try again or try text messaging me. The past few days that I have been attempting the survey has been a bit difficult for me because I am use to always answering with “hello.” However, I made a concerted effort and achieved good results for this project. My friend, Savina, and I were planning on hanging out Thursday afternoon. I waited for her to pick me up at the CRCC business building. She called me when she arrived, and I answered her phone call, but didn’t say a word. This (non-conversation) silence lasted for 23 seconds and then she asked “hello Caroline, are you there?” I did not expect this patient reaction from her. After we met, I asked her why she waited on the phone for a whole 23 seconds instead of saying something immediately. Her response to why she didn’t say something sooner and instead...

Nurses and Telephone Liabiity

...Telephone calls from patients seeking a nurse's advice have increased. Accordingly, nursing informatics must include and address the issue of providing telephone consultations to patients, whether one is a nurse on-call or a triage nurse. Nurses must also be certain that any person they are responsible for supervising understands how to address telephone consultations as well (Buppert, C., 2008). Telephone consultations can be beneficial in that minor illnesses can be addressed without an office visit, recurring problems can be addressed without an office visit and the cost of an office visit is reduced (Medical Insurance Exchange of California (MIEC), 2008). Despite the benefits, telephone consultations can also create liability risks. In many ways they pose a higher level of risk than in-person consultations because there are certain observations that cannot be made over the telephone and a first-hand examination is not being completed (Sosin, 2006). The nurse must use their best judgment in evaluating the patients statements. Depending on the position of the nurse, there are several ways that a patient telephone call can be handled. The nurse can refer the patient to their treating health care provider, refer the patient to the facility call center or “try to gather enough information to give the patient sound professional advice”(Austin, 2008, p. 6). If the nurse decides to address the patient's issue themselves, they should make sure that they are not “exceeding...

Telephone Network

...switched telephone network The public switched telephone network (PSTN) is one of the world's public circuit-switched telephone networks. Originally PSTN is a network of fixed-line analogue telephone systems. Today, the PSTN is totally digital in its core and also includes mobile along with fixed (plain old telephone service, POTS) telephones. Early History The first telephones were in private use, had no network and were wired together in pairs. If a user wanted to talk to different people, he had as many telephones as necessary for that purpose. A user who wished to speak whistled into the transmitter till the other party heard him. Soon, a bell was added for giving signal, and then a switch hook was also added, and telephones took advantage of the exchange principle that was already implemented in telegraph networks. Each telephone was connected through wires to a local telephone exchange, and the exchanges were connected together with trunks. Networks were connected together in a hierarchical manner till they spanned to cities, countries, continents and oceans. This was the beginning of the PSTN, the term PSTN was not known for many decades. Pulse dialling between the phone and the exchange was introduced through Automation, and then among exchanges, followed by more sophisticated address signalling including the multi-frequency. Digital Channel Although this network was made by using analogue voice connections through manual switchboards, then automated telephone exchanges...

The Telephone, the Device That Changed the Way We Communicate

...The Telephone, the Device that Changed the Way We Communicate The Telephone, the Device that Changed the Way We Communicate Voice communication is the most commonly used way of expressing our wants, needs and thoughts. The telephone changed the way we communicate. It has been allowing people to talk in almost real time without seeing each other since its development in 1876. Until then, mail and the telegraph was the normal and only means to talk across the country. Although it was effective, those methods were all silent. Now with the telephone, you could truly convey your feelings to someone in a personal way. The other end could hear the happiness, the sadness, or the anger in your voice. Can you imagine life today without it? The telephone, which means far speaking in Greek, was developed in 1784. For years many people were working to bring this concept into reality. In March 10, 1876 a functioning model was completed by Alexander Graham Bell. “Mr. Watson, come here, I want you!” (Casson, p.12) were the first words spoken by Bell to his assistant, Thomas A. Watson. Finally, after many years of working on a way to transmit the voice over wires, Bell was successful with his design and protection of his product. He even had the foresight to have the patent paper work already done days before his invention was working. The next task would be getting people to use the telephone. When the telephone was invented it wasn’t very popular. In fact people didn’t...
