The Answer: The Telephone. The telephone was invented first. No one invented the telephone after It was already invented in I was talking on the telephone. A landline telephone is connected by a wire to the telephone network, while a mobile or cell phone is portable and communicates with the telephone network by radio. Alexander Graham Bell invented the telephone. The Telephone was invented by Alexander Graham Bell :. Contact BSNL customer service.
Alexander Graham Bell invented the telephone and obtained the patent on it in Nobody knows when the string telephone was invented as far as I know , but I do know that the tin can telephone was invented in Alexander Graham Bell invented the telephone in Alexander Graham Bell invented the gallows telephone. The string telephone mimics the use of a landline phone. Popular with science projects, a string telephone used vibrations to produce acoustic sounds.
Log in. See Answer. Best Answer. Alexander Grand Bell. Study guides. Q: Who invented the landline telephone? Write your answer The first telephone call happened on March 10, , a few days after the Scottish-born inventor received a patent for the device. Watson, come here — I want to see you! Controversy continues over who actually invented the phone first. While Bell won the series of court battles over the first patent, some historians still give credit to Elisha Gray or Antonio Meucci, both of whom had been working on similar devices.
In fact, in , the U. Phones started out as novelty items shown just to kings and queens. Today, they are something almost everyone carries with them, even the homeless. In , at the start of World War I, there were 10 people for every working telephone in the U. By the end of World War II in , there were five people for every working phone.
The technology passed a key milestone in , when there was one phone for every man, woman and child in the U. About three-quarters of those numbers were tied to mobile phones, a little over 10 percent were for old-fashioned landlines, and the rest were for internet-enabled phones. Until then, the company had a monopoly over most of the U. That changed in , when the U. Consumers in all parts of the country suddenly had the option to buy their own phone.
One reason phones have become so indispensable for communicating is that the cost keeps dropping to make calls. But after Bell's two other brothers died of tuberculosis, Bell and his parents decided to immigrate to Canada in After a brief period of living in Ontario, the Bells moved to Boston where they established speech-therapy practices specializing in teaching deaf children to speak.
One of Alexander Graham Bell's pupils was a young Helen Keller, who when they met was not only blind and deaf but also unable to speak. Although working with the deaf would remain Bell's principal source of income, he continued to pursue his own studies of sound on the side. Bell's unceasing scientific curiosity led to the invention of the photophone , significant commercial improvements in Thomas Edison's phonograph, and to the development of his own flying machine just six years after the Wright Brothers launched their plane at Kitty Hawk.
As President James Garfield lay dying of an assassin's bullet in , Bell hurriedly invented a metal detector in an unsuccessful attempt to locate the fatal slug. The telegraph and telephone are both wire-based electrical systems. Alexander Graham Bell's success with the telephone came as a direct result of his attempts to improve the telegraph.
When he began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years. Although a highly successful system, the telegraph was basically limited to receiving and sending one message at a time.
Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to consider the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of a "multiple telegraph" had been in existence for some time, it was purely conjecture as no one had been able to fabricate one—until Bell.
His "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch. By October , Bell's research had progressed to the extent that he could inform his future father-in-law, Boston attorney Gardiner Greene Hubbard, about the possibility of a multiple telegraph.
Hubbard, who resented the absolute control then exerted by the Western Union Telegraph Company, instantly saw the potential for breaking such a monopoly and gave Bell the financial backing he needed.
Bell proceeded with his work on the multiple telegraph but did not tell Hubbard that he and Thomas Watson, a young electrician whose services he had enlisted, were also developing a device that would transmit speech electrically. While Watson worked on the harmonic telegraph at the insistent urging of Hubbard and other backers, Bell secretly met in March with Joseph Henry , the respected director of the Smithsonian Institution, who listened to Bell's ideas for a telephone and offered encouraging words.
Spurred on by Henry's positive opinion, Bell and Watson continued their work. By June , the goal of creating a device that would transmit speech electrically was about to be realized. They had proven that different tones would vary the strength of an electric current in a wire. To achieve success, therefore, they needed only build a working transmitter with a membrane capable of varying electronic currents and a receiver that would reproduce these variations in audible frequencies.
On June 2, , while experimenting with the harmonic telegraph, the men discovered that sound could be transmitted over a wire completely by accident. Watson was trying to loosen a reed that had been wound around a transmitter when he plucked it by accident. The vibration produced by that gesture traveled along the wire into a second device in the other room where Bell was working. The "twang" Bell heard was all the inspiration that he and Watson needed to accelerate their work. They continued to work into the next year.
Bell recounted the critical moment in his journal: "I then shouted into M [the mouthpiece] the following sentence: 'Mr. Watson, come here—I want to see you. The first telephone call had just been made. Bell patented his device on March 7, , and it quickly began to spread. By , construction of the first regular telephone line from Boston to Somerville, Massachusetts, had been completed.
By the end of , there were over 49, telephones in the United States. Transcontinental service began in Bell founded his Bell Telephone Company in As the industry rapidly expanded, Bell quickly bought out competitors.
After a series of mergers, the American Telephone and Telegraph Co. It would maintain its control over the U. The first regular telephone exchange was established in New Haven, Connecticut, in Early telephones were leased in pairs to subscribers.
The subscriber was required to put up his own line to connect with another.
