how did alexander graham bell invent the telephone

Bell pointed to a variable resistance device in his previous application in which he described a cup of mercury, not water. Sure enough, the U.S. government decided to weigh in and brought fraud charges against Alexander Graham Bell. Bell's principle rival, Elisha Gray, also presented an invention at this . [29][failed verification], His father encouraged Bell's interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. According to some accounts, the metal detector worked flawlessly in tests but did not find Guiteau's bullet, partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. Bell concentrated on experimenting with electricity to convey sound and later installed a telegraph wire from his room in Somerset College to that of a friend. [51] Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved. With no formal training, he mastered the piano and became the family's pianist. A wealthy lawyer and politician, Hubbard was supporting Bells experiments financially but would not let him marry his daughter, Mabel, until he had perfected his invention! [160] Garfield's surgeons, led by self-appointed chief physician Doctor Willard Bliss, were skeptical of the device, and ignored Bell's requests to move the President to a bed not fitted with metal springs. To help celebrate his life, his wife asked guests not to wear black (the traditional funeral color) while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson's "Requiem":[191]. Let us know if you have suggestions to improve this article (requires login). Each pupil would play an important role in the next developments. Alexander Graham Bell is often credited as the inventor of the telephone since he was awarded the first successful patent. [147][N 19] Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family. Then in 1887 they sold their patents to the American Graphophone Company, which later evolved into the Columbia Phonograph Company. But could Bell truly lay claim to inventing the telephone? Updates? With little convincing, visitors believed his dog could articulate "How are you, grandmama? In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk. Marian was born only days after Bell and his assistant. In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims. It is most likely that both Bell and Gray independently devised their telephone designs as an outgrowth of their work on harmonic telegraphy. Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity. [96][97] The final test certainly proved that the telephone could work over long distances, at least as a one-way call. But few know that the central interest of his life was education for deaf children or that he was one of the strongest proponents of oralism in the United States. They had rides in the Forlanini hydrofoil boat over Lake Maggiore. Bell had a lasting impact on a variety of fields beyond the telephone, including optical telecommunications, hydrofoils, and aeronautics, and served as the second . [113] The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. When we think of an inventor, we often think of someone with a singular passion for whatever it is that they're . Until Now", https://en.wikipedia.org/w/index.php?title=Alexander_Graham_Bell&oldid=1138226265, Marian Hubbard Bell (18801962) who was referred to as "Daisy". In 1984, the former AT&T agreed to divest its local telephone operations but retain its long distance, R&D and manufacturing arms. The arrangement was for teacher and student to continue their work together, with free room and board thrown in. [182] Other members of the board included Luther Burbank, Roswell H. Johnson, Vernon L. Kellogg, and William E. Alexander Graham Bell was the first to secure a patent for the telephone, but only just. [63] In 1893, Keller performed the sod-breaking ceremony for the construction of Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf".[64][65]. Birth City: Chelsea. Why did Alexander Graham Bell invent the telephone? There is considerable debate about who arrived first and Gray later challenged the primacy of Bell's patent. Phone listing (1848-1849)National Museums Scotland. His efforts resulted in a remarkably lifelike head that could "speak", albeit only a few words. Although Edison had invented the phonograph in 1877, he soon turned his attention to other technologies, especially electric power and lighting, and his machine, which recorded and reproduced sound on a rotating cylinder wrapped in tinfoil, remained an unreliable and cumbersome device. The elder Bell took great efforts to have his young pupil learn to speak clearly and with conviction, the attributes that his pupil would need to become a teacher himself. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant,[N 13] and the two of them experimented with acoustic telegraphy. In 1879, the Bell company acquired Edison's patents for the carbon microphone from Western Union. His mother was almost deaf, and his father taught elocution to the deaf, influencing Alexanders later career choice as teacher of the deaf. Gender: Male. Alexander Graham Bell died on 2 August 1922 aged 75. Soon after filing their patents, Bell and Watson had perfected their new invention, and the telephone was ready for the public. He also developed medical technology. In August of that year, he was on the receiving end of the first one-way long-distance call, transmitted from Brantford to nearby Paris, Ontario, over a telegraph wire. In 1903 his son-in-law, Gilbert H. Grosvenor, became editor in chief of the National Geographic Magazine, and Bell encouraged Grosvenor to make the magazine a more popular publication through more photographs and fewer scholarly articles. [107][108], The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. Prior to perfecting the telephone, Alexander Graham Bell invented and demonstrated the harmonic telegraph at the Centennial Exposition of 1876, held in Philadelphia's Fairmount Park. When he was just 12, the young Alexander invented a device with rotating paddles and nail brushes that could quickly remove husks from wheat grain to help improve a farming process. At age 16,. These so-called harmonic telegraphs used reeds or tuning forks that responded to specific acoustic frequencies. You likely already know that Alexander Graham Bells telephone invention changed the world. Most notably, Bell is credited for his invention of the telephone, which grew out of his research on the telegraph. Steve Jobs, left, and Alexander Graham Bell. Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat. On June 21, 1880, Bell's assistant transmitted a wireless voice telephone message a considerable distance, from the roof of the Franklin School in Washington, D.C., to Bell at the window of his laboratory, some 700 feet (213m) away, 19 years before the first voice radio transmissions.[153][154][155][156]. In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Bell was in his laboratory with this latest experimental version of a telephone transmitter. [48][N 7], At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his "dreaming place",[50] a large hollow nestled in trees at the back of the property above the river. (1870's)National Museums Scotland. [151][152] Both men later became full associates in the Volta Laboratory Association. His older brother Melville had married and moved out. [80] When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. [68] Bell has been criticised by members of the Deaf community for supporting ideas that could cause the closure of dozens of deaf schools, and what some consider eugenicist ideas. This type of model was used to teach anatomy students the complexities of human vocal physiognomy. [23] Bell's preoccupation with his mother's deafness led him to study acoustics. Alexander Graham Bell, one year younger than Lars Magnus Ericsson, had been born in Edinburgh. [213] The French government conferred on him the decoration of the Lgion d'honneur (Legion of Honor); the Royal Society of Arts in London awarded him the Albert Medal in 1902; the University of Wrzburg, Bavaria, granted him a PhD, and he was awarded the Franklin Institute's Elliott Cresson Medal in 1912. [150] 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. Bells other major undertaking was the development of an electrical bullet probe, an early version of the metal detector, for surgical use. By the summer of 1875 he had succeeded in transmitting sounds, though still not recognisable speech, on a gallows frame telephone like this one. [28] The following year, he attended the University of Edinburgh, joining his older brother Melville who had enrolled there the previous year. In 1881 they successfully sent a photophone message nearly 200 metres between two buildings. [183] A summary of the event notes that Bell was a "pioneering investigator in the field of human heredity". And it almost cost him his marriage At the age of eleven he chose to add the middle name Graham, which stuck for the rest of his life. The pair demonstrated the probe in the autumn of 1881. Of Alexander Graham Bell's 19th century invention of the telephone, Thomas Edison said it "annihilated time and space and brought the human family in closer touch." It is true that having the ability to hear the voices of loved ones over great distances changed how the American people . He sketched out a rudimentary diagram of the transmitter and receiver, and the very next day, he and Watson were experimenting on the worlds first telephone. 1876 1876 Having lost her hearing after a near-fatal bout of scarlet fever close to her fifth birthday,[74][75][N 11] she had learned to read lips but her father, Gardiner Greene Hubbard, Bell's benefactor and personal friend, wanted her to work directly with her teacher. 174,465 dated March 7, 1876, and No. Inspired to Invent Bell was born in Edinburgh, Scotland, in 1847. Many of the lawsuits became rancorous, with Elisha Gray becoming particularly bitter over Bell's ascendancy in the telephone debate, but Bell refused to launch a countersuit for libel. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." So before the genius idea for Alexander Graham Bells telephone invention came along, he first set out to improve upon the telegraph. [citation needed], Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. With aspirations to obtain a degree at University College London, Bell considered his next years as preparation for the degree examinations, devoting his spare time at his family's residence to studying. The property consisted of an orchard, large farmhouse, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River. In fact, his tinkering and experimentation with the telegraph was just a passion project. His younger brother, Edward "Ted," was similarly affected by tuberculosis. This led him and Bell to the development of practical hydrofoil watercraft. Bell's parents embarked upon a long-planned move when they realized that their remaining son was also sickly. The transmitter comprised three partsa drumlike device (a cylinder with a covered end), a needle, and a battery. Elisha Gray, 1876, designed a telephone using a water microphone in Highland Park, Illinois. Bell began working with her in 1873, when she was 15 years old. Meucci was born in Florence, Italy, and began testing early telephone models there. His father published a variety of works on the subject, several of which are still well known, especially his The Standard Elocutionist (1860),[21] which appeared in Edinburgh in 1868. Bell would later write that he had come to Canada a "dying man". In the bedroom, his assistant Watson waited with a reed receiver pressed against his ear. [9][N 3]. [131] One unusual request exacted by his fiance was that he use "Alec" rather than the family's earlier familiar name of "Aleck". He continued his research in sound and endeavored to find a way to transmit musical notes and articulate speech, but although absorbed by his experiments, he found it difficult to devote enough time to experimentation. The stamp became, and remains to this day, the most valuable one of the series.[218]. Bell colluded with The USA Patent Office agent to steal the device and designs from their rightful owner, an Italian inventor name Antonio Meu. Upon his brother's death, Bell returned home in 1867. So the inventor of the telephone left promptly to recover the bones of the man who had given the United State $508,418 (about $10 million today) to create an institution for the "increase and . His mother and his wife were both deaf, and he was devoted to the cause of helping the deaf community. Edisons work culminated in the quadruplex, a system for sending four simultaneous telegraph messages over a single wire. Although Alexander Graham Bell is best remembered as the inventor of the telephone, he invented other devices too. Articles from Britannica Encyclopedias for elementary and high school students. There he also devoted himself to improving the phonograph. [15] Born as just "Alexander Bell", at age 10, he made a plea to his father to have a middle name like his two brothers. [78] Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. Bell's success was due to his sound experiments, as well as his family's desire to assist the deaf in communicating. Alexander passed the entrance examinations for University College London in June 1868 and matriculated there in the autumn. Bell sought to use this property to develop the photophone, an invention he regarded as at least equal to his telephone. The vibrations were then converted into an electric current which traveled along the wire to the receiver. In 1876, Watson plucked a spring in one room, and the sound came through on a receiver in the other. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. [44], In 1870, 23-year-old Bell travelled with his parents and his brother's widow, Caroline Margaret Ottaway,[45] to Paris, Ontario,[46] to stay with Thomas Henderson, a Baptist minister and family friend. Controversy remains as to whether Bell or his father-in-law might have had access to the details of Grays patent through a patent office clerk in Hubbards pay. [103] Influential visitors to the exhibition included Emperor Pedro II of Brazil. The Bell stamp became very popular and sold out in little time. In 1868, not long before he departed for Canada with his family, Bell completed his matriculation exams and was accepted for admission to University College London. This depth of knowledge made Alexander Graham Bell one of the greatest inventors of all time. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. By this time, his parents had moved to Canada then Boston, and Bell was heavily invested in his invention processes. What year was Alexander Graham Bell the inventor of the telephone? As with many innovations, the idea for the telephone came along far sooner than it was brought to reality. [121] However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002, stated that Meucci's "work in the invention of the telephone should be acknowledged". Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. But while Bell encountered failure in his long career, it did not stop him from exploring new ideas. And in 1891-92, he served as AIEE president.

Bell was in Boston on February 14 and did not arrive in Washington until February 26. In November 1920, Bell returned to Edinburgh for a visit. His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. Sensing potential, he. [101] Bell's investors would become millionaires while he fared well from residuals and at one point had assets of nearly one million dollars. [41] Throughout late 1867, his health faltered mainly through exhaustion. (1877-01-12)LIFE Photo Collection. Nevertheless, it contributed to research into the photovoltaic effect that had practical applications later in the 20th century. When did Alexander Graham Bell invent the telephone? Bell travelled the country promoting his invention, even demonstrating the device to Queen Victoria, who was so amused she asked to keep the temporary installation in place. Alexander (Graham was not added until he was 11) was born to Alexander Melville Bell and Eliza Grace Symonds. At age 11 he entered the Royal High School at Edinburgh, but he did not enjoy the compulsory curriculum, and he left school at age 15 without graduating. He did experimental work on aeronautics and hydrofoils. Alexander Graham Bell had pioneered a system called visible speech, developed by his father, to teach deaf children. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. 2 His father and grandfather were elocution experts, known today as speech pathologists. Alexander Graham Bells observations about how sound traveled along a wire gave rise to his idea of transmitting a human voice in the same manner. The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. Omissions? He had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires. By the 1870s, telegraph wire connected cities across the globe. In 1876, Alexander Graham Bell invented the telephone. On March 7, 1876, 29-year-old Alexander Graham Bell receives a patent for his revolutionary new invention: the telephone. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. "[180] The paper's author concludes by saying "A wiser way to prevent the extension of hereditary deafness, it seems to us, would be to continue the investigations which Dr. Bell has so admirable begun until the laws of the transmission of the tendency to deafness are fully understood, and then by explaining those laws to the pupils of our schools to lead them to choose their partners in marriage in such a way that deaf-mute offspring will not be the result. A scientific notebook in which Alexander Graham Bell recorded his invention of the telephone and the first words ever spoken by phone, as well as correspondence from his assistant, Thomas Watson, are among the last items added to an online collection of the Alexander Graham Bell Family Papers. Best Known For: Lewis Howard Latimer was an inventor . He was an enthusiastic boater, and Bell and his family sailed or rowed a long series of vessels on Bras d'Or Lake, ordering additional vessels from the H.W. Bell decided that a promising approach was to use an induction balance, a by-product of his research on canceling out electrical interference on telephone wires. In 1880, Alexander Graham Bell and Tainter developed a device they called the "photophone," which transmitted sound on a beam of light. That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. The first telephones - called box telephones because of their shape - went on sale later that year. At the age of eleven he chose to add the middle name. He could decipher Visible Speech representing virtually every language, including Latin, Scottish Gaelic, and even Sanskrit, accurately reciting written tracts without any prior knowledge of their pronunciation. [219] Additionally, the Government of Canada honored Bell in 1997 with a C$100 gold coin, in tribute also to the 150th anniversary of his birth, and with a silver dollar coin in 2009 in honor of the 100th anniversary of flight in Canada. In February, they successfully sent a photophone message nearly 200 metres between two buildings.
