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. Methane gas, he reasoned, could be produced from the waste of farms and factories. This time, guests at the household distinctly heard people in Brantford reading and singing. The telegraph was one of the most important inventions of its time. When Bell spoke the sentence "Mr. WatsonCome hereI want to see you" into the liquid transmitter,[87] Watson, listening at the receiving end in an adjoining room, heard the words clearly. The harmonic telegraph served as the basis for the modern telephone. While Italian innovator Antonio Meucci (pictured at left) is credited with inventing the first basic phone in 1849, and Frenchman Charles Bourseul devised a phone in 1854, Alexander Graham Bell won the first U.S. patent for the device in 1876. 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]. He attended classes in anatomy and physiology in London for several years, building his understanding of how speech and hearing worked. [185] His last view of the land he had inhabited was by moonlight on his mountain estate at 2:00a.m.[N 25][188][N 26] While tending to him after his long illness, Mabel, his wife, whispered, "Don't leave me." 174,465 dated March 7, 1876, and No. (Photos by AP) Article. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. In 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Bell's success came . 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. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site. Bell had a specially made table where he could place his notes and equipment inside a locking cover. Although the offer was made by George's mother and followed the year-long arrangement in 1872 where her son and his nurse had moved to quarters next to Bell's boarding house, it was clear that Mr. Sanders was backing the proposal. Bell sought to use this property to develop the photophone, an invention he regarded as at least equal to his telephone. Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, Trouve. The machines sound was so convincing that the landlady looked for a crying baby, only to find the boys admiring their invention in the stairwell. Remarkably, he only worked on his invention because he misunderstood a technical work he had read in German. Bell used the prize money to set up his Volta Laboratory, an institution devoted to studying deafness and improving the lives of the deaf, in Washington, D.C. With little convincing, visitors believed his dog could articulate "How are you, grandmama? 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." At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. 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. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels. Inspired to Invent Bell was born in Edinburgh, Scotland, in 1847.

On 10 March 1876, three days after the publication of his patent, Alexander Graham Bell made history with a peremptory instruction to his assistant Thomas Watson: Mr Watson, come hereI want to see you Crackly and indistinct, but intelligible, the words were the first to be spoken over the telephone. Replica of gallows frame telephone (1937)National Museums Scotland. Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph". Bell's research indicated that a hereditary tendency toward deafness, as indicated by the possession of deaf relatives, was an important element in determining the production of deaf offspring. And in 1891-92, he served as AIEE president. 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. Alexander Graham Bell was awarded the first U.S. patent for the invention of the telephone in 1876. [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. Associate Professor of History, University at Albany, State University of New York. Pinaud's experience in boatbuilding enabled him to make useful design changes to the HD-4. Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. His mother was almost deaf, and his father taught elocution to the deaf, influencing Alexanders later career choice as teacher of the deaf. The covered end of the drumlike device was attached to the needle. He is best remembered as the inventor of the telephone (1876). The pair demonstrated the probe in the autumn of 1881. History Through Deaf Eyes - The Influence of Alexander Graham Bell. A top speed of 54 miles per hour (87km/h) was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. Professor Alexander Graham Bell's New Machine, Built After Plans by Lieutenant Selfridge, Shown to Be Practicable by Flight Over, The aileron had been conceived of as early as 1868 by British inventor. 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. Bell was the companys technical adviser until he lost interest in telephony in the early 1880s. Married. Author of. Bell quickly disassembled it and effected a repair, to the owner's amazement. [170] Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908. At age 16,. He realized it would be possible to convey the human voice across a wire. Bell considered the invention of the hydroplane as a very significant achievement. [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). A year later Bell moved to the United States, where he taught speech to deaf students. [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. 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. Through study and experimentation, Bell hypothesised that if sound waves could be converted into a fluctuating electric current, then that current could then be reconverted into sound waves identical to the original at the other end of the circuit. [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. 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. Starting in 1891, inspired by the research of American scientist Samuel Pierpont Langley, he experimented with wing shapes and propeller blade designs. [84], Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. One of the judges at the Exhibition, Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, described the telephone as "the greatest by far of all the marvels of the electric telegraph". Why did Alexander Graham Bell invent the telephone? Alexander Graham Bell died on 2 August 1922 aged 75. The Scottish-born Bell worked in London with his father,. His father and grandfather were elocution experts, known today as speech pathologists. Best of Philly. Alexander Graham Bell, (born March 3, 1847, Edinburgh, Scotlanddied August 2, 1922, Beinn Bhreagh, Cape Breton Island, Nova Scotia, Canada), Scottish-born American inventor, scientist, and teacher of the deaf whose foremost accomplishments were the invention of the telephone (1876) and the refinement of the phonograph (1886). [57] He was subsequently asked to repeat the programme at the American Asylum for Deaf-mutes in Hartford, Connecticut, and the Clarke School for the Deaf in Northampton, Massachusetts. After the hard work of Bell and his team, the first message of Alexander Graham Bell was delivered to his assistant Mr. Watson. On the evening of March 10, 1876, Watson heard Alecs voice emanating from the receiver in the next room, Mr. [126][N 16], The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell delayed the German patent application, the electrical firm of Siemens & Halske set up a rival manufacturer of Bell telephones under their own patent. [8] His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Illustration of Bell's equipment used (1877)National Museums Scotland. Gardiner Hubbard organized a group that established the Bell Telephone Company in July 1877 to commercialize Bells telephone. Alexander began to promote the telephone and improve on the telegraph. It took 18 years and over 550 court cases, but Alexander Graham Bell won every battle. Today the vast majority of all our telecommunication travels the globe at the speed of light along fibre optic cables. [111] Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court,[112] but none was successful in establishing priority over the original Bell patent[113][114] and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. [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. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and 10 per session. You probably learned in school that it was Alexander Graham Bell who invented the telephone. Among the major sites are: In 1880, Bell received the Volta Prize with a purse of 50,000 French francs (approximately US$290,000 in today's dollars[202]) for the invention of the telephone from the French government. Both his father and grandfather were well-known teachers of elocution and speech training; his father in Edinburgh, his grandfather in London. Bell understood that if sound could be transmitted as an electrical current, it would be possible for a receiver to interpret those vibrations. In Bells luggage was his new communication device, the telephone. The word "hello," it appears, came straight from the fertile brain of the wizard of Menlo Park, N.J., who . [127] The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. Henry replied that Bell had "the germ of a great invention". He claimed he showed Gray's patent caveat to Bailey. He said, "Mr. Watson, come here I want to see you" and Watson soon appeared at his side. 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. [100], Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000, equal to $2,544,688 today. [47] The Bell family soon purchased a farm of 10.5 acres (4.2ha) at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario. "[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." 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. A. D. McCurdyBaldwin and McCurdy being new engineering graduates from the University of Toronto.[168]. Bell's success was due to his sound experiments, as well as his family's desire to assist the deaf in communicating. Bell and his assistant Charles Sumner Tainter jointly invented a wireless telephone, named a photophone, which allowed for the transmission of both sounds and normal human conversations on a beam of light. But do you know the real story behind how the first telephone invention came to be? [41] Throughout late 1867, his health faltered mainly through exhaustion. 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. Please refer to the appropriate style manual or other sources if you have any questions. And it almost cost him his marriage. [110], As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. [citation needed], Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. On that same day a few hours later or was it a few hours earlier? inventor Elisha Gray of Highland Park, Illinois, filed his own idea for a telephone device at the same office.Bell was granted the patent on 7 March 1876, just three days before his first successful transmission. Score: 4.1/5 (16 votes) . Thomas Edison invented the carbon microphone which produced a strong telephone signal. In fact, on the 7 March 1876, he got the official patent for it. [125] Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions. [189] He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren. It was invented in 1876 by Alexander Graham Bell. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. Sound and speech were part of Bells life from a young age. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. 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. June 3, 1880. Castle. 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. At a speech given to pupils at the citys Royal High School, where he had been a student 60 years before, he imagined that this young generation might live to see a time when someone in any part of the world would be able to telephone to any other part of the world without any wires at all. [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. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Alexander Graham Bell was the first to secure a patent for the telephone, but only just. The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. 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. The origin of this effort was the shooting of U.S. President James A. Garfield in July 1881. Articles from Britannica Encyclopedias for elementary and high school students. page 1 of 3. [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 first produced intelligible speech on March 10, 1876, when he summoned his laboratory assistant, Thomas A. Watson, with words that Bell transcribed in his lab notes as Mr. Finally, in 1877, Alexander Graham Bell and his business partners established the Bell Telephone Company and began manufacturing the device. His father, Alexander Melville Bell, inspired him greatly and often set him to task with innovative challenges. "[180], Historians have noted that Bell explicitly opposed laws regulating marriage, and never mentioned sterilization in any of his writings. [146][N 20] The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Watson, come here, I want to see you!. But could Bell truly lay claim to inventing the telephone?

Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. [177] The paper is a compilation of data on the hereditary aspects of deafness. The Alexander Graham Bell Memorial Park, which features a broad neoclassical monument built in 1917 by public subscription. 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. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. This type of model was used to teach anatomy students the complexities of human vocal physiognomy. He had two brothers: Melville James Bell (18451870) and Edward Charles Bell (18481867), both of whom would die of tuberculosis. 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. [209][210] Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. Bell's report to the U.S. Navy permitted him to obtain two 350-horsepower (260-kilowatt) engines in July 1919. [174] He specifically wanted to see if selective breeding could produce sheep with four functional nipples with enough milk for twin lambs. Bell had a lasting impact on a variety of fields beyond the telephone, including optical telecommunications, hydrofoils, and aeronautics, and served as the second . 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. 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. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound"[86][N 14] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat. [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. In 1984, the former AT&T agreed to divest its local telephone operations but retain its long distance, R&D and manufacturing arms. Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (later to become the public Horace Mann School for the Deaf)[56] to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favour of his son. [24], As a young child, Bell, like his brothers, received his early schooling at home from his father. [73] Mabel was a bright, attractive girl who was ten years Bell's junior but became the object of his affection. Hello didn't become "hi" until the telephone arrived. [149], Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied.
