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). Others transmitted a sound or a click or a buzz but our boys [Bell and Watson] were the first to transmit speech one could understand.". He also developed medical technology. Bell was in his laboratory with this latest experimental version of a telephone transmitter. By the 1870s, telegraph wire connected cities across the globe. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech. He founded the Aerial Experiment Association in 1907. In this treatise, his father explains his methods of how to instruct deaf-mutes (as they were then known) to articulate words and read other people's lip movements to decipher meaning. Author of. And I laid me down with a will. In 1865 the family moved to London. The result was a contraption that he dubbed the ear phonautograph. A person could speak into the machine, and a pen attached to a membrane would react by tracing a line. 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. In 1984, the former AT&T agreed to divest its local telephone operations but retain its long distance, R&D and manufacturing arms. [84], Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. The project that Bell himself called his greatest achievement in 1880 he named the photophone. But he had no working model to demonstrate the feasibility of these ideas. Finally, in 1877, Alexander Graham Bell and his business partners established the Bell Telephone Company and began manufacturing the device. At an early age, he was enrolled at the Royal High School, Edinburgh, which he left at the age of 15, having completed only the first four forms. A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. But Thomas Alva Edison coined the greeting. [212] He also served for many years as a Regent of the Smithsonian Institution (18981922). The queen considered the process to be "quite extraordinary" although the sound was "rather faint". 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. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. The needle was connected by wire to the battery, and the battery was connected by wire to a receiver.

The transmitter comprised three partsa drumlike device (a cylinder with a covered end), a needle, and a battery. Although the trio briefly experimented with the concept, they could not develop a workable prototype. Bells proximity to the hearing impaired informed his work in sound science. On March 7, 1876, the Patent Office awarded Bell what is said to be one of the most valuable patents in history. [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. [13] The family home was at South Charlotte Street, and has a stone inscription marking it as Bell's birthplace. 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. This was a method of transmitting sound in a beam of light using a light sensitive selenium cell to translate the light density into electric signals. 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 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. 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 bel (B) and the smaller decibel (dB) are units of measurement of sound pressure level (SPL) invented by Bell Labs and named after him. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. Tel. He was born into a family of elocutionists and speech therapists, and he used his knowledge of anatomy and physiology to develop the telephone. Henry replied that Bell had "the germ of a great invention". Encouraged by his father, young Bell attempted to make working models of ears and vocal cords, aiming to create a mechanical speech device. They worked well in the laboratory but proved unreliable in service. 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. [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. The story of the telephone begins with Alexander Graham Bell's terrier. Alexander Graham Bell, one of the fathers of the telephone Through vibrations, sound was transferred. Phone listing (1848-1849)National Museums Scotland. 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. Both his father and grandfather were well-known teachers of elocution and speech training; his father in Edinburgh, his grandfather in London. 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! 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". 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. [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. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. [184] Bell had also been affected by pernicious anemia. Bell was fascinated by the machine and after he obtained a copy of von Kempelen's book, published in German, and had laboriously translated it, he and his older brother Melville built their own automaton head. Following the death of both of Bells brothers from tuberculosis, in 1870 the family emigrated to start a healthier life in Canada. 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. 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." As publicity mounted, so did the pressure to get the telephone into production. On February 14, 1876, Gray filed a caveat with the U.S. Patent Office for a telephone design that used a water transmitter. Father of Prof. A. G. Bell Developed Sign Language for Mutes", "Before Inventing The Telephone, Alexander Graham Bell Tried To Teach His Dog To Talk", "Charles Sumner Tainter and the Graphophone", "Image 1 of Pamphlet by Alexander Graham Bell, 1898", "Alexander Graham Bell and His Role in Oral Education", "Alexander Graham Bell - Helpful or Harmful? Both his mother and wife were deaf. [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. [25] His school record was undistinguished, marked by absenteeism and lacklustre grades. [7] 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. Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity. 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]. [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). When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" [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. 1 2 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 . [102], Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public. Baldwin described it as being as smooth as flying. That same morning, Bell's lawyer filed Bell's application with the patent office. The word "hello," it appears, came straight from the fertile brain of the wizard of Menlo Park, N.J., who . 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. In addition, Bell's grandfather, father and brother all shared an interest in speech and elocution. He had two brothers: Melville James Bell (18451870) and Edward Charles Bell (18481867), both of whom would die of tuberculosis. 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. Before Bell's invention, the fastest method to send a message was by using the Morse code through telegraph lines. 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. 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. Why Alexander Graham Bell invented the telephone? - Short-Fact In a footnote, Bell adds, "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus."[161]. 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. Alexander Graham Bell's invention of the telephone in 1876, was a world-changing event which was also a breakthrough in communication. On February 23, 1909, Bell was present as the Silver Dart flown by J. Alexander made the telephone in 1876. On the evening of March 10, 1876, Watson heard Alecs voice emanating from the receiver in the next room, Mr. The first telephone had two parts: a transmitter and a receiver. [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. Graham Bell Birth Anniversary: The Evolution of Telephones in - News18 The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf. What problems did Alexander Graham Bell faced when inventing the telephone? [59] Returning to Boston in fall 1873, Bell made a far-reaching decision to concentrate on his experiments in sound. His mother and his wife were both deaf, and he was devoted to the cause of helping the deaf community. In the bedroom, his assistant Watson waited with a reed receiver pressed against his ear. How did Alexander Graham Bells telephone work? Did alexander graham bell invent the phonograph? Bell had a specially made table where he could place his notes and equipment inside a locking cover. Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. One of Bells students was Mabel Hubbard, daughter of Gardiner Greene Hubbard, a founder of the Clarke School. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone".[214]. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. [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. Alexander Graham Bell: Telephone & Inventions - HISTORY Sound and speech were part of Bells life from a young age. Did Alexander Graham Bell Steal The Telephone Patent? 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. After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. (Photos by AP) Article. Why did the telephone get invented? - Sage-Answer He claimed he showed Gray's patent caveat to Bailey. He supported the journal Science, which later became the official publication of the American Association for the Advancement of Science. 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. In fact, his tinkering and experimentation with the telegraph was just a passion project. Who invented the telephone? | Live Science Alexander Graham Bell, one of the fathers of the telephone There he also devoted himself to improving the phonograph. [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. It took 18 years and over 550 court cases, but Alexander Graham Bell won every battle. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. [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. [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]. Alexander Graham Bell 's Telephone Invention In 1876, Watson plucked a spring in one room, and the sound came through on a receiver in the other. Hello didn't become "hi" until the telephone arrived. However, there was no way to transmit a person's voice through a telegram. 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. At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father. Under the direction of the Boston architects. [81] Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.[82].
