how did alexander graham bell invent the telephone

[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. Bell's March 10, 1876, laboratory notebook entry describing his first successful experiment with the telephone. In 1867, Bell and his family moved to London so that he and his remaining brother could study at better schools. In 1873 British scientist Willoughby Smith discovered that the element selenium, a semiconductor, varied its electrical resistance with the intensity of incident light.

[58][N 10] The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed. [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". [14] His father was Alexander Melville Bell, a phonetician, and his mother was Eliza Grace Bell (ne Symonds). [130] Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. He wanted to use this to help teach deaf people, who had never heard spoken words, to speak. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. [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. A bullet lodged in the presidents back, and doctors were unable to locate it through physical probing. [95], Continuing his experiments in Brantford, Bell brought home a working model of his telephone. This time, guests at the household distinctly heard people in Brantford reading and singing. [162] The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. [115], On January 13, 1887, the U.S. Government moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation. The first telephone had two parts: a transmitter and a receiver. The transmitter comprised three partsa drumlike device (a cylinder with a covered end), a needle, and a battery. 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. Pinaud's experience in boatbuilding enabled him to make useful design changes to the HD-4. The next step would be to find investors. Tomas Farley also writes that "Nearly every scholar agrees that Bell and Watson were the first to transmit intelligible speech by electrical means. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Hello didn't become "hi" until the telephone arrived. 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. [125] Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions. This test was said by many sources to be the "world's first long-distance call". During the 1890s Bell shifted his attention to heavier-than-air flight. [184] Bell had also been affected by pernicious anemia. In one memorable incident, the newly arrived Bells were walking down one of Baddeck's central streets when Bell peered into a storefront window and saw a frustrated shopkeeper fiddling with his problematic telephone. The telegraph was one of the most important inventions of its time. Associate Professor of History, University at Albany, State University of New York. But his work on the harmonic telegraph was hugely influential in his quest to transmit the human voice itself. But Thomas Alva Edison coined the greeting. In 1865, when the Bell family moved to London,[40] Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment. His older brother Melville had married and moved out. If I had been able to read German in those days, I might never have commenced my experiments! [211] The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness. 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. However, the question of priority of invention between the two has been controversial from the very beginning. [148], Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened. [146][N 20] The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. 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 1870 Bell and his family emigrated to Canada. But he had no working model to demonstrate the feasibility of these ideas. Bell and his father before him studied . [160] Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus. Bell considered the photophone "the greatest invention [he had] ever made, greater than the telephone." This effect was of great importance to Alexander Graham Bells telephone idea. Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph". [79], In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". An obstacle Alexander Graham Bell faced was that others claimed they had invented the telephone or had the idea before Bell. Meucci's testimony in this case was disputed due to a lack of material evidence for his inventions, as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. In 1936, the US Patent Office declared Bell first on its list of the country's greatest inventors,[217] leading to the US Post Office issuing a commemorative stamp honoring Bell in 1940 as part of its 'Famous Americans Series'. [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. The word "hello," it appears, came straight from the fertile brain of the wizard of Menlo Park, N.J., who . His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. Inspired to Invent Bell was born in Edinburgh, Scotland, in 1847. Bell typically signed his name in full on his correspondence. It was invented in 1876 by Alexander Graham Bell. The harmonic telegraph served as the basis for the modern telephone. ", At 25 to 30 Miles an Hour. This depth of knowledge made Alexander Graham Bell one of the greatest inventors of all time. 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. Let us know if you have suggestions to improve this article (requires login). Bell was inspired in part by Australian aeronautical engineer, "Selfridge Aerodrome Sails Steadily for 319 feet (97m). On March 7, 1876, the Patent Office awarded Bell what is said to be one of the most valuable patents in history. He succeeded his father-in-law, Gardiner Hubbard, as president of the National Geographic Society (18981903). Bells proximity to the hearing impaired informed his work in sound science. Bell was thrilled at his recognition by the Six Nations Reserve and throughout his life would launch into a Mohawk war dance when he was excited. 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. This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. 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). However, in May 1870, Melville died from complications due to tuberculosis, causing a family crisis. Most notably, Bell is credited for his invention of the telephone, which grew out of his research on the telegraph. 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. Alexander Graham Bells telephone invention amazed visitors at The Centennial International Exhibition of 1876. Alexander Graham Bell plaque (1847)National Museums Scotland. As with many innovations, the idea for the telephone came along far sooner than it was brought to reality. 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. By 1885 Bell and his colleagues (his cousin Chichester A. Although Alexander Graham Bell is best remembered as the inventor of the telephone, he invented other devices too. [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". Two days later, Bell described what happened in his laboratory notebook: I then shouted into M [the mouthpiece] the following sentence: Mr Watson come here I want to see you. "To my delight he came and declared that he had heard and understood what I said. The 150th anniversary of Bell's birth in 1997 was marked by a special issue of commemorative 1 banknotes from the Royal Bank of Scotland. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate. Bell pointed to a variable resistance device in his previous application in which he described a cup of mercury, not water. Author of. The stamp became, and remains to this day, the most valuable one of the series.[218]. 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. 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. Nevertheless, it contributed to research into the photovoltaic effect that had practical applications later in the 20th century. The vibrations were then converted into an electric current which traveled along the wire to the receiver. The Bell stamp became very popular and sold out in little time. 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. Some hardships that Alexander Graham Bell faced were he had two brothers that died of tuberculosis. [33]" Indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". [23] Bell's preoccupation with his mother's deafness led him to study acoustics. [81] Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.[82]. Birth State: Massachusetts. 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. Bell died at his Nova Scotia estate, where he was buried. He was a skilled inventor and businessman, and he played a major role in the development of the telecommunications . Bell is also credited with developing one of the early versions of a metal detector through the use of an induction balance, after the shooting of U.S. President James A. Garfield in 1881. In fact, on the 7 March 1876, he got the official patent for it. [51] Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved. [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. He made a telephone call via telegraph wires and faint voices were heard replying. [7], Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf; profoundly influencing Bell's life's work. In the 1830s he moved to Cuba and, while working on methods to treat illnesses with electric shocks, found that sounds could travel by electrical impulses through copper wire. The Bell Telephone Company quickly established a commercial infrastructure that could support the booming demand. One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. Under the direction of the Boston architects. [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. Encouraged by his father, young Bell attempted to make working models of ears and vocal cords, aiming to create a mechanical speech device. In his final, and some of his most productive years, Bell split his residency between Washington, D.C., where he and his family initially resided for most of the year, and Beinn Bhreagh, where they spent increasing amounts of time. [166], Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. 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. After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. alexander graham belltelephonealexander graham bell telephonehistory of the telephone,what did alexander graham bell invent,who invented the telephonetelepho. Acting decisively, Alexander Melville Bell asked Bell to arrange for the sale of all the family property,[42][N 6] conclude all of his brother's affairs (Bell took over his last student, curing a pronounced lisp),[43] and join his father and mother in setting out for the "New World". [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. Though inventions like the Corliss steam engine seemed to be the mightiest, the telephone commanded attention for its utility to the average person. Upon his brother's death, Bell returned home in 1867. Bell had a lasting impact on a variety of fields beyond the telephone, including optical telecommunications, hydrofoils, and aeronautics, and served as the second . While Bell recovered (by then referring to himself in correspondence as "A. G. Bell") and served the next year as an instructor at Somerset College, Bath, England, his brother's condition deteriorated. What year was Alexander Graham Bell the inventor of the telephone? Here are some the things he invented: The Metal Detector - Bell invented the first metal detector which was used to try and find a bullet inside of President James Garfield. Alexander Graham Bell was the first to secure a patent for the telephone, but only just. Alexander Began to test out new ideas through a long life. Even after Bell agreed to engage with scientists conducting eugenic research, he consistently refused to support public policy that limited the rights or privileges of the deaf. Both men rushed their respective designs for these prototype telephones to the patent office within hours of each other. Steve Jobs, left, and Alexander Graham Bell. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. On 10 March 1876, the first intelligible telephone communication was made. Alexander began to promote the telephone and improve on the telegraph. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They write new content and verify and edit content received from contributors. [12], Bell was born in Edinburgh, Scotland, on March 3, 1847. In 1876, Watson plucked a spring in one room, and the sound came through on a receiver in the other. Gardiner Hubbard organized a group that established the Bell Telephone Company in July 1877 to commercialize Bells telephone. Omissions? That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. With a change in administration and charges of conflict of interest (on both sides) arising from the original trial, the US Attorney General dropped the lawsuit on November 30, 1897, leaving several issues undecided on the merits. "[141][pageneeded][142] Despite this declaration, Bell has been proudly claimed as a "native son" by all three countries he resided in: the United States, Canada, and the United Kingdom. Alexander was the founder of 'The Bell telephone Company', and in the same year he married Mabel Hubbard and went on a yearlong honeymoon travelling all around Europe. In 2006, Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. 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. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. 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. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford, Ontario, in 1917.[198]. Bell would later write that he had come to Canada a "dying man". However, you may not know that the man who invented the telephone, Alexander Graham Bell (1847-1922) had another invention that used light to transmit sound. In later years, Bell described the invention of the telephone and linked it to his "dreaming place". On February 14, 1876, Gray filed a caveat with the U.S. Patent Office for a telephone design that used a water transmitter. The first telephones - called box telephones because of their shape - went on sale later that year. [70] Although, in his memoir Memoir upon the Formation of a Deaf Variety of the Human Race, Bell observed that if deaf people tended to marry other deaf people, this could result in the emergence of a "deaf race". 2 On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. In 1892, he made the ceremonial call to open long distance telephone service between New York and Chicago, and in 1915 the call to open service between New York and San Francisco. Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments. The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. Alexander Graham Bell was particularly interested in developing technology to assist the deaf community. In 1863, Bell was . Building on his fathers earlier work on the human voice, Bell moved to the United States in 1871 and started teaching deaf students in Boston. In 1871, Bell invented a "harmonic telegraph," for which he received a patent. 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. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses. 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 . Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.D.s (Doctorate of Laws), two Ph.D.s, a D.Sc., and an M.D. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Although his invention rendered him independently wealthy, he sold off most of his stock holdings in the company early and did not profit as much as he might have had he retained his shares. [citation needed], Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Portrait of Alexander Graham Bell (1915)LIFE Photo Collection. [189] He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren.
