how did alexander graham bell invent the telephone
However, he did not complete his studies, because in 1870 the Bell family moved again, this time immigrating to Canada after the deaths of Bells younger brother Edward in 1867 and older brother Melville in 1870, both of tuberculosis. Elisha Gray, 1876, designed a telephone using a water microphone in Highland Park, Illinois. He realized it would be possible to convey the human voice across a wire. On September 9, 1919, the HD-4 set a world marine speed record of 70.86 miles per hour (114.04 kilometres per hour),[164] a record which stood for ten years. In September 1885 the Bell family vacationed in Nova Scotia, Canada, and immediately fell in love with the climate and landscape. The telegraph was one of the most important inventions of its time. 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. Alexander Graham Bell was the first to secure a patent for the telephone, but only just. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. [24], As a young child, Bell, like his brothers, received his early schooling at home from his father. The first telephone had two parts: a transmitter and a receiver. Edisons work culminated in the quadruplex, a system for sending four simultaneous telegraph messages over a single wire. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. [128][N 17]. Two years later, he was appointed Professor of Vocal Physiology and Elocution at Boston University. They worked well in the laboratory but proved unreliable in service. [53][N 9]. Updates? 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. The third test on August 10, 1876, was made via the telegraph line between Brantford and Paris, Ontario, eight miles (thirteen kilometres) distant. Watson, come here, I want to see you!. 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 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. Bell pointed to a variable resistance device in his previous application in which he described a cup of mercury, not water. (1877-01-12)LIFE Photo Collection. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. The story of Alexander Graham Bell and Canada's greatest invention is told in one teen pop song. [92], The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. 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. 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. They write new content and verify and edit content received from contributors. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells. Bell sought to use this property to develop the photophone, an invention he regarded as at least equal to his telephone. June 3, 1880. AMBLF 503 Washington Ave. # 186Chestertown, MD 21620. Bells other major undertaking was the development of an electrical bullet probe, an early version of the metal detector, for surgical use. 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. Did you know that Bells amazing invention--the telephone--stemmed from his work on teaching the deaf? [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. American inventor Alexander Graham Bell (1847-1922) with one of his inventions, circa 1910. He was able to demonstrate that the photophone was technologically feasible, but it did not develop into a commercially viable product. The vibrations were then converted into an electric current which traveled along the wire to the receiver. Alexander Began to test out new ideas through a long life. His fathers work focused on developing a system of visible speech, which allowed speech sounds to be written down. In 1881 they successfully sent a photophone message nearly 200 metres between two buildings. In June he demonstrated his telephone to the judges of the Philadelphia Centennial Exhibition, a test witnessed by Brazils Emperor Pedro II and the celebrated Scottish physicist Sir William Thomson. However, the question of priority of invention between the two has been controversial from the very beginning. As with many innovations, the idea for the telephone came along far sooner than it was brought to reality. 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. 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. [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 needle was connected by wire to the battery, and the battery was connected by wire to a receiver. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. On February 23, 1909, Bell was present as the Silver Dart flown by J. 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. [119][120] Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. And I laid me down with a will. In later years, Bell described the invention of the telephone and linked it to his "dreaming place". He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. [130] Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. He supported the journal Science, which later became the official publication of the American Association for the Advancement of Science. 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. 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. History Through Deaf Eyes - The Influence of Alexander Graham Bell. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. To give the organization scientific credibility, Davenport set up a Board of Scientific Directors naming Bell as chairman. 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. Alexander Graham Bell plaque (1847)National Museums Scotland. [157] The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. The first patent for such a device was his, but the . Alexander Graham Bell was a Scottish-born scientist and inventor best known for inventing the first working telephone in 1876 and founding the Bell Telephone Company in 1877. Alexander Graham Bell Invented the Photophone. [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. He succeeded his father-in-law, Gardiner Hubbard, as president of the National Geographic Society (18981903). [20] In return, Ben's father John Herdman gave both boys the run of a small workshop in which to "invent".[20]. 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 first telephone to become popular was a box-shaped device with a crank on the side and a receiver held to the ear. It was Bell's first in a very long line of practical and famous inventions. [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. [189][194], Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew. 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. Other inventions included: a sound recorder and player called a graphophone and a metal detector for bullets He died in Canada. The transmitter comprised three partsa drumlike device (a cylinder with a covered end), a needle, and a battery. 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. Mabel and Bell mobilized the community to help victims in Halifax. [171] Bell had worried that the flight was too dangerous and had arranged for a doctor to be on hand. Methane gas, he reasoned, could be produced from the waste of farms and factories. [28] The following year, he attended the University of Edinburgh, joining his older brother Melville who had enrolled there the previous year. 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. You probably learned in school that it was Alexander Graham Bell who invented the telephone. While his older brother seemed to achieve success on many fronts including opening his own elocution school, applying for a patent on an invention, and starting a family, Bell continued as a teacher. This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. 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. [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. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone".[214]. [104], On January 14, 1878, at Osborne House, on the Isle of Wight, Bell demonstrated the device to Queen Victoria,[105] placing calls to Cowes, Southampton and London. Bell also kept a proud eye on the progress of his invention. It was invented in 1876 by Alexander Graham Bell. Bell later shifted his attention to aerial technology. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, Trouve. [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 number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada. Bells story will fascinate young readers interested in the early history of modern technology [107][108], The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. 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. The next step would be to find investors. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father. Alexander Graham Bell was a remarkable man who overcame many obstacles in his life. 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. In 1907 Bell founded the Aerial Experiment Association, which made significant progress in aircraft design and control and contributed to the career of pioneer aviator Glenn Hammond Curtiss. In 1876, Alexander Graham Bell invented the telephone. During the year he spent with his grandfather, a love of learning was born, with long hours spent in serious discussion and study. 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. [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". It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880, at Bell's laboratory at 1325 L Street in Washington, D.C. On the morning of February 14, 1876, a representative for Alexander Graham Bell handed in a patent application to the patent office in Washington for an apparatus for transmitting vocal sounds via electricity lines. [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). [30] The boys would carefully adjust the "lips" and when a bellows forced air through the windpipe, a very recognizable Mama ensued, to the delight of neighbours who came to see the Bell invention.[31]. Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own". Phone listing (1848-1849)National Museums Scotland. There is considerable debate about who arrived first and Gray later challenged the primacy of Bell's patent. His father and grandfather were elocution experts, known today as speech pathologists. Tel. With no formal training, he mastered the piano and became the family's pianist. Images are: A model of Bell's very first telephone (top-left). 174,465 dated March 7, 1876, and No. 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. Bell also had a strong influence on the National Geographic Society[11] and its magazine while serving as the second president from January 7, 1898, until 1903. 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. Helping his father in Visible Speech demonstrations and lectures brought Bell to Susanna E. Hull's private school for the deaf in South Kensington, London. On August 3, 1876, from the telegraph office in Brantford, Ontario, Bell sent a tentative telegram to the village of Mount Pleasant four miles (six kilometres) distant, indicating that he was ready. But the technology was limited in its capacity because it could transmit only one message at a time. But do you know the real story behind how the first telephone invention came to be? Known as the father of the telephone, Alexander Graham Bell's invention historically changed how people communicated. 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". 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. Replica of gallows frame telephone (1937)National Museums Scotland. [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". He and his assistant, Charles Tainter, developed a device they called the "photophone," which transmitted sound on a beam of light. [118], During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. 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. Bell's patent was approved and officially registered on March 7, and three days later the famous call is said to have been made when Bell's summons to his assistant ("Mr Watson, come here. Bell Company engineers made numerous other improvements to the telephone, which emerged as one of the most successful products ever. The first telephones - called box telephones because of their shape - went on sale later that year.
