how did alexander graham bell invent the telephone

"[177], A review of Bell's "Memoir upon the Formation of a Deaf Variety of the Human Race" appearing in an 1885 issue of the "American Annals of the Deaf and Dumb" states that "Dr. Bell does not advocate legislative interference with the marriages of the deaf for several reasons one of which is that the results of such marriages have not yet been sufficiently investigated." That summer, the Bells had a vacation on Cape Breton Island in Nova Scotia, spending time at the small village of Baddeck. Our editors will review what youve submitted and determine whether to revise the article. Alexander Graham Bell invented the telephone. Updates? 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]. On February 23, 1909, Bell was present as the Silver Dart flown by J. The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of 60. Model of larynx (1860)National Museums Scotland. Alexander Began to test out new ideas through a long life. He was born into a family of elocutionists and speech therapists, and he used his knowledge of anatomy and physiology to develop the telephone. How was the technology developed and improved? [25] His school record was undistinguished, marked by absenteeism and lacklustre grades. 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. At the age of 12, Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation at the mill and used steadily for a number of years. After the hard work of Bell and his team, the first message of Alexander Graham Bell was delivered to his assistant Mr. Watson. [176], In November 1883, Bell presented a paper at a meeting of the National Academy of Sciences titled "Upon the Formation of a Deaf Variety of the Human Race". Alexander Graham Bell was the first to secure a patent for the telephone, but only just. 4041 (image 22)", "Alexander Graham Bell 18471922 Inventor of the Bell System", "Invention of the Telephone National Historic Event", "Inventing the TelephoneAnd Triggering All-Out Patent War", "Bell's centennial telephone transmitter, 1876", "140 Years Since the First Telephone Call to Queen Victoria on the Isle of Wight", "Alexander Graham Bell demonstrates the newly invented telephone", "pdf, Letter from Alexander Graham Bell to Sir Thomas Biddulph, February 1, 1878", "United States V.

A year later Bell moved to the United States, where he taught speech to deaf students. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. You likely already know that Alexander Graham Bells telephone invention changed the world. Henry replied that Bell had "the germ of a great invention". [212] He also served for many years as a Regent of the Smithsonian Institution (18981922). They called their device the Graphophone and applied for patents, which were granted in 1886. He also developed medical technology. The first telephone to become popular was a box-shaped device with a crank on the side and a receiver held to the ear. The project that Bell himself called his greatest achievement in 1880 he named the photophone. Bell considered himself more of a teacher of the deaf than an inventor, but he is best known for inventing the telephone, which he considered an intrusion on his work as a scientist. After the shooting of U.S. Pres. So before the genius idea for Alexander Graham Bells telephone invention came along, he first set out to improve upon the telegraph. [106] She later asked to buy the equipment that was used, but Bell offered to make "a set of telephones" specifically for her. Hello didn't become "hi" until the telephone arrived. This plaque (on the right) is outside Alexander Graham Bells birthplace in Charlotte Square, Edinburgh. [208][bettersourceneeded] The Volta Prize was conceived by Napoleon III in 1852, and named in honor of Alessandro Volta, with Bell becoming the second recipient of the grand prize in its history. In 1880 he began research on using light as a means to transmit sound. Bell later shifted his attention to aerial technology. Birth date: September 4, 1848. But Meucci didn't give up easily, and he improved his prototypes. Still widely known as the inventor of the telephone, by his early thirties Bell had given up his interest in this invention. 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. The paper did not propose sterilization of deaf people or prohibition on intermarriage,[179] noting that "We cannot dictate to men and women whom they should marry and natural selection no longer influences mankind to any great extent. Alexander Graham Bell was a remarkable man who overcame many obstacles in his life. Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old "Georgie" Sanders, deaf from birth, and 15-year-old Mabel Hubbard. Hubbard's financial support to the research efforts fell far short of the funds needed, necessitating Bell to continue teaching while conducting his experiments. [132][133] They had four children: The Bell family home was in Cambridge, Massachusetts, until 1880 when Bell's father-in-law bought a house in Washington, D.C.; in 1882 he bought a home in the same city for Bell's family, so they could be with him while he attended to the numerous court cases involving patent disputes. In 1906, Davenport, who was also the founder of the American Breeder's Association, approached Bell about joining a new committee on eugenics chaired by David Starr Jordan. During his world tour of 191011, Bell and Baldwin met with Forlanini in France. While days and evenings were occupied by his teaching and private classes, Bell began to stay awake late into the night, running experiment after experiment in rented facilities at his boarding house. [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. 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. In 1871, Bell invented a "harmonic telegraph," for which he received a patent. When Bell was just a teenager, he and his brother invented a speaking machine that could mimic the voice of a baby saying mama. They studied their fathers anatomy books and recreated the elements of a human mouth and vocal cords. [27] At the age of 16, Bell secured a position as a "pupil-teacher" of elocution and music, in Weston House Academy at Elgin, Moray, Scotland. While pursuing his teaching profession, Bell also began researching methods to transmit several telegraph messages simultaneously over a single wirea major focus of telegraph innovation at the time and one that ultimately led to Bells invention of the telephone. His father, Alexander Melville Bell, inspired him greatly and often set him to task with innovative challenges. On 11 August 1877, Bell and his wife Mabel arrived in Britain from the USA on honeymoon. [76], By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success.

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. [128][N 17]. The pair demonstrated the probe in the autumn of 1881. [107][108], The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. The telegraph was one of the most important inventions of its time. The property consisted of an orchard, large farmhouse, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River. However, in May 1870, Melville died from complications due to tuberculosis, causing a family crisis. That same morning, Bell's lawyer filed Bell's application with the patent office. Heres how he did it. At the end of July, he began searching for Garfields bullet, but to no avail. But his work on the harmonic telegraph was hugely influential in his quest to transmit the human voice itself. The stamp became, and remains to this day, the most valuable one of the series.[218]. Encouraged by his father, young Bell attempted to make working models of ears and vocal cords, aiming to create a mechanical speech device. Bell typically signed his name in full on his correspondence. [32] After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". Answer (1 of 12): Bell never invented the telephone, and a few years ago history and The USA courts finally got the story straight by releasing the facts. Alexander Graham Bell is often credited as the inventor of the telephone since he was awarded the first successful patent. A replica of liquid transmitter telephone (1870's)National Museums Scotland. Bell understood that if sound could be transmitted as an electrical current, it would be possible for a receiver to interpret those vibrations. alexander graham belltelephonealexander graham bell telephonehistory of the telephone,what did alexander graham bell invent,who invented the telephonetelepho. [145] By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory,[146] were begun that the Bells would name Beinn Bhreagh (Gaelic: Beautiful Mountain) after Bell's ancestral Scottish highlands. [189][203][204][205][206][207] Among the luminaries who judged were Victor Hugo and Alexandre Dumas, fils. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. [16][N 4] For his 11th birthday, his father acquiesced and allowed him to adopt the name "Graham", chosen out of respect for Alexander Graham, a Canadian being treated by his father who had become a family friend. He was the inventor of the hydrofoil boat, a man-carrying kite, the aileron, a moveable part of an airplane wing that helps control rolling, and the landing/take-off airplane tricycle gear. [88], Although Bell was, and still is, accused of stealing the telephone from Gray,[89] Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment,[90] to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. From his laboratory in Boston, Bell applied his knowledge of phonetics to create a harmonic telegraph. He wanted to make a telegraph that could send several different notes simultaneously on the same wire. This revelation became the genesis for Alexander Graham Bells telephone invention. In later years, Bell described the invention of the telephone and linked it to his "dreaming place". And I laid me down with a will. Yesterday afternoon [on January 25, 1915], the same two men talked by telephone to each other over a 3,400-mile wire between New York and San Francisco. From his early years, Bell showed a sensitive nature and a talent for art, poetry, and music that was encouraged by his mother. [71] Ultimately, in 1880, the Second International Congress on Education of the Deaf passed a resolution preferring the teaching of oral communication rather than signing in schools. 174,465 dated March 7, 1876, and No. Bell's principle rival, Elisha Gray, also presented an invention at this . Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever. [7] This depth of knowledge made Alexander Graham Bell one of the greatest inventors of all time. It was a bright twang, and it sounded the same on the receiver as when Watson plucked it. Bell's success came through his experiments in sound and the furthering of his family's interest in assisting the deaf with communication. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. With the successful flight, the AEA disbanded and the Silver Dart would revert to Baldwin and McCurdy, who began the Canadian Aerodrome Company and would later demonstrate the aircraft to the Canadian Army. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and 10 per session. As with many innovations, the idea for the telephone came along far sooner than it was brought to reality. Soon after filing their patents, Bell and Watson had perfected their new invention, and the telephone was ready for the public. Thanks to his contributions, communications continue to expand and improve across the globe, allowing people to stay connected from virtually anywhere. Birth Country: United States. 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. [215] [N 28][216] Since 1976, the IEEE's Alexander Graham Bell Medal has been awarded to honor outstanding contributions in the field of telecommunications. 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. Gender: Male. The first telephone had two parts: a transmitter and a receiver. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. Alexander Graham Bell . | Start ASL", "Eugenics and Deaf People in 20th Century America", "Alexander Graham Bell and Thomas Watson", "Underrated entrepreneur: Thomas Edison's overlooked business story", "Alexander Graham Bell Lab notebook pp. The queen considered the process to be "quite extraordinary" although the sound was "rather faint". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. The next step would be to find investors. [140], Bell was a British subject throughout his early life in Scotland and later in Canada until 1882 when he became a naturalized citizen of the United States. [citation needed], On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray's design. Surgeons adopted it, and it was credited with saving lives during the Boer War (18991902) and World War I (191418). Bells idea was that he could speak into it, and when his pupil mimicked him, they could compare the lines and help the deaf improve their pronunciation. [84], Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. Illustration of Bell's equipment used (1877)National Museums Scotland. But while Bell encountered failure in his long career, it did not stop him from exploring new ideas. [24] Bell became so proficient that he became a part of his father's public demonstrations and astounded audiences with his abilities. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. [113] Bell's laboratory notes and family letters were the key to establishing a long lineage to his experiments. To give the organization scientific credibility, Davenport set up a Board of Scientific Directors naming Bell as chairman. Calling from the AT&T head office at 15 Dey Street in New York City, Bell was heard by Thomas Watson at 333 Grant Avenue in San Francisco. A group of investors led by Gardiner Hubbard wanted to establish a federally chartered telegraph company to compete with Western Union by contracting with the Post Office to send low-cost telegrams. Reluctantly, Bell also had to conclude a relationship with Marie Eccleston, who, as he had surmised, was not prepared to leave England with him. [N 12] While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. 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! [113] The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. Bell patented his telephone first and later emerged the victor in a legal dispute with Gray. The transmitter comprised three partsa drumlike device (a cylinder with a covered end), a needle, and a battery. [21] Bell was also deeply affected by his mother's gradual deafness (she began to lose her hearing when he was 12), and learned a manual finger language so he could sit at her side and tap out silently the conversations swirling around the family parlour. If I had been able to read German in those days, I might never have commenced my experiments! How did Alexander Graham Bells telephone work? These early experiments in speech creation, along with his knowledge of anatomy, informed his own experiments on transmitting speech, which he began in earnest from 1873. Bell developed several sonic technologies, including the photophone (1880) and the Graphophone (1886). [181], Bell's interest and research on heredity attracted the interest of Charles Davenport, a Harvard professor and head of the Cold Spring Harbor Laboratory. Married. At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. [169] On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America. [41] Throughout late 1867, his health faltered mainly through exhaustion. On March 3, 1847, Alexander Graham Bell was born, the man who is credited in popular culture with the invention of the first working telephone. The arrangement was for teacher and student to continue their work together, with free room and board thrown in. While recovering, he discovered his wife had sold everything in his lab for $6. Under the direction of the Boston architects. Finally, he and Hubbard worked out an agreement that Bell would devote most of his time to the harmonic telegraph but would continue developing his telephone concept. History Through Deaf Eyes - The Influence of Alexander Graham Bell. Today the vast majority of all our telecommunication travels the globe at the speed of light along fibre optic cables. Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. The clerk seemed to admit as much in a later court case, but Bells patent was upheld, as it was in the many cases which followed. Their final aircraft design, the Silver Dart, embodied all of the advancements found in the earlier machines. Tomas Farley also writes that "Nearly every scholar agrees that Bell and Watson were the first to transmit intelligible speech by electrical means. Glad did I live and gladly die [24], As a young child, Bell, like his brothers, received his early schooling at home from his father. The notion of transmitting a voice seemed too far-fetched and futuristic when the telegraph still reigned. 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. Mabel and Bell mobilized the community to help victims in Halifax. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses. In the last years of his life, as his final projects wound down, Bell and his wife, their extended family and friends, lived exclusively at their beloved Beinn Bhreagh. [98], The first two-way (reciprocal) conversation over a line occurred between Cambridge and Boston (roughly 2.5 miles) on October 9, 1876. He noted that the proportion of deaf children born to deaf parents was many times greater than the proportion of deaf children born to the general population. It will ever be a source of pride to our country that the great invention, with which his name is immortally associated, is a part of its history. [35], Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork "contraption", Bell pored over the German scientist's book. 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 . In fact, his tinkering and experimentation with the telegraph was just a passion project. A large number of Bell's writings, personal correspondence, notebooks, papers, and other documents reside in both the United States Library of Congress Manuscript Division (as the Alexander Graham Bell Family Papers),[197] and at the Alexander Graham Bell Institute, Cape Breton University, Nova Scotia; major portions of which are available for online viewing. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. In 1879, the Bell company acquired Edison's patents for the carbon microphone from Western Union. [158][159] Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use. [122][123][124] This did not put an end to the still-contentious issue. When asked how he was able to do so Bell only needed to introduce himself. Over the course of more than 30 years, Bell sought to produce a breed of sheep with multiple nipples that would bear twins. Wilber also claimed (after Bell arrived in Washington D.C. from Boston) that he showed Gray's caveat to Bell and that Bell paid him $100 (equivalent to $2,500 in 2021). Although Alexander Graham Bell is best remembered as the inventor of the telephone, he invented other devices too. Portrait of Alexander Graham Bell (1915)LIFE Photo Collection. A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. Alexander Graham Bell invented the first phone with the help of Thomas A Watson, which created certain sound waves and electric currents. Alexander Graham Bell ( / re.m /, born Alexander Bell; March 3, 1847 - August 2, 1922) [4] was a Scottish-born [N 1] inventor, scientist and engineer who is credited with patenting the first practical telephone. [61][62] While he was working as a private tutor, one of his pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. [N 22][N 23] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). In 1876, Watson plucked a spring in one room, and the sound came through on a receiver in the other. A. D. McCurdyBaldwin and McCurdy being new engineering graduates from the University of Toronto.[168]. [93], The patent examiner, Zenas Fisk Wilber, later stated in an affidavit that he was an alcoholic who was much in debt to Bell's lawyer, Marcellus Bailey, with whom he had served in the Civil War.
