Her soothing voice helped usher in a new era of telecommunications and In his 84 years, Thomas Edison acquired a record number of 1, patents singly or jointly and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras.
He was an impassioned champion of a strong federal government, and played a key role in defending Serbian-American engineer and physicist Nikola Tesla made dozens of breakthroughs in the production, transmission and application of electric power.
He invented the first alternating current AC motor and developed AC generation and transmission technology.
In , Connecticut-born gun manufacturer Samuel Colt received a U. Colt founded a company to manufacture his revolving-cylinder pistol; however, sales were slow and the By turns charismatic and ruthless, brilliant and power hungry, diplomatic and The internet got its start in the United States more than 50 years ago as a government weapon in the Cold War.
For years, scientists and Live TV. This Day In History. History at Home. Telephone In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time.
While the Bell Company faced over court challenges, in the end, none were successful. Inventions and Accomplishments In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields.
Some of his other notable inventions were: The metal detector: Bell initially came up with this device to locate a bullet inside of assassinated President James A.
Photophone: The photophone allowed transmission of speech on a beam of light. Graphophone: This improved version of the phonograph could record and play back sound.
Zwar scheiterten diese Versuche, doch hatte Bell damit die Voraussetzungen für die Konstruktion eines funktionierenden Telefons geschaffen.
Am März führte Alexander Graham Bell mit seinem Mitarbeiter Watson, der sich im Nebenzimmer befand, sein erstes Telefongespräch mit diesem damals noch sehr merkwürdig aussehenden Apparat.
So konnte er dann die erste transamerikanische Sprechverbindung zwischen San Franzisko und New York einweihen. Bis zu seinem Tode im Jahre beschäftigte sich Bell mit vielen weiteren Entwicklungen und Erfindungen auf zahlreichen technischen Gebieten.
National Geographic Society. To the end of his days, when discussing himself, Bell would always add with pride "I am a teacher of the deaf".
When he moved to Canada in , Canadian and British citizenship were functionally identical, with Canadian citizenship only becoming a formal classification in He applied for American citizenship after , gained it in , and referred to himself as an American citizen from that point on.
Quote from Bell speaking to his wife: "you are a citizen because you can't help it — you were born one, but I chose to be one. On October 24, , in Brantford, Ontario, the Governor General spoke at the unveiling of the Bell Telephone Memorial to an audience numbering in the thousands, saying: "Dr.
Bell is to be congratulated upon being able to receive the recognition of his fellow citizens and fellow countrymen".
Bell's dislike of the telephone. Of course, he never had one in his study. That was where he went when he wanted to be alone with his thoughts and his work.
The telephone, of course, means intrusion by the outside world. And the little difficulties and delays often attending the establishment of conversation But all really important business over the telephone he transacted himself.
There are few private houses more completely equipped with telephones than ours Bell was more particular about than our telephone service We never could have come here [to Beinn Bhreagh] in the first place or continued here, but for the telephone which kept us in close touch with doctors and neighbors and the regular telegraph office Bell did like to say in fun, "Why did I ever invent the Telephone," but no one had a higher appreciation of its indispensableness or used it more freely when need was—either personally or by deputy —and he was really tremendously proud of it and all it was accomplishing.
It received its historical designation from the Government of Canada on June 1, Mabel's exact age when she became deaf would later play a part in the debate on the effectiveness of manual versus oral education for deaf children , as children who are older at the onset of deafness retain greater vocalization skills and are thus more successful in oral education programs.
Some of the debate centred on whether Mabel had to relearn oral speech from scratch, or whether she never lost it.
It was invented in Brantford at Tutela Heights in the summer of 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.
Bell was so ecstatic that he wanted to jointly name his new invention and his new daughter Photophone Greek: " light—sound " ,   Bell wrote: "Only think!
Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. Bell quickly disassembled it and effected a repair, to the owner's amazement.
When asked how he was able to do so Bell only needed to introduce himself. Bell also chose maroon-colored silk as it would show up clearly against the light-colored sky in his photographic studies.
Views of an Expert. Hammondsport , New York, March 12, Boulton and was also created independently by Robert Esnault-Pelterie and several others.
Attending the formal ceremony were Bell's daughter, Mrs. To each side of the portico facing the monument are the engraved inscriptions "In Grateful Recognition of the Inventor of the Telephone".
Its dedication was broadcast live nationally by the Canadian Broadcasting Corporation. His wife, Mabel, daughter Daisy, and son-in-law David Fairchild had gathered around him.

Archived from the original on October 15, Retrieved December 29, He founded the Aerial Experiment Association in The first telephone had two parts: a transmitter and a receiver.
The transmitter comprised three parts—a drumlike device a cylinder with a covered end , a needle, and a battery. The covered end of the drumlike device was attached to the needle.
The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate.
The vibrations were then converted into an electric current which traveled along the wire to the receiver. At age 11 he entered the Royal High School at Edinburgh , but he did not enjoy the compulsory curriculum, and he left school at age 15 without graduating.
In the family moved to London. Alexander passed the entrance examinations for University College London in June and matriculated there in the autumn.
Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever. Bell began working with her in , when she was 15 years old. Despite a year age difference, they fell in love and were married on July 11, They had four children, Elsie — , Marian — , and two sons who died in infancy.
In Joseph Stearns had invented the duplex, a system that transmitted two messages simultaneously over a single wire. Inventors then sought methods that could send more than four; some, including Bell and his great rival Elisha Gray , developed designs capable of subdividing a telegraph line into 10 or more channels.
These so-called harmonic telegraphs used reeds or tuning forks that responded to specific acoustic frequencies.
They worked well in the laboratory but proved unreliable in service. 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, however, was more interested in transmitting the human voice. Finally, he and Hubbard worked out an agreement that Bell would devote most of his time to the harmonic telegraph but would continue developing his telephone concept.
From harmonic telegraphs transmitting musical tones, it was a short conceptual step for both Bell and Gray to transmit the human voice.
Bell filed a patent describing his method of transmitting sounds on February 14, , just hours before Gray filed a caveat a statement of concept on a similar method.
On March 7, , the Patent Office awarded Bell what is said to be one of the most valuable patents in history.
It is most likely that both Bell and Gray independently devised their telephone designs as an outgrowth of their work on harmonic telegraphy. However, the question of priority of invention between the two has been controversial from the very beginning.
Despite having the patent, Bell did not have a fully functioning instrument. He first produced intelligible speech on March 10, , when he summoned his laboratory assistant, Thomas A.
