He announced his invention of the first phonograph, a device for recording and replaying sound, on November 21, 1877 ( early reports appear in Scientific American and several newspapers in the beginning of November, and an even earlier announcement of Edison working on a ' talking-machine ' can be found in the Chicago Daily Tribune on May 9 ), and he demonstrated the device for the first time on November 29 ( it was patented on February 19, 1878 as US Patent 200, 521 ).

Edison patented the sound recording and reproducing phonograph in 1878.

Edison patented what he found, but he did not understand the underlying physics, nor did he have an inkling of the potential value of the discovery.

In the United States, Thomas Edison, in the mid-1880s, patented an electromagnetic induction system he called " grasshopper telegraphy ", which allowed telegraphic signals to jump the short distance between a running train and telegraph wires running parallel to the tracks.

* February 19 – The phonograph is patented by Thomas Edison.

In 1890, Louis Glass and William S. Arnold invented the nickel-in-the-slot phonograph, the first of which was an Edison Class M Electric Phonograph retrofitted with a device patented under the name of Coin Actuated Attachment for Phonograph.

What is known about Woodward's discovery is that it was patented in Canada and the United States prior to a patent being granted to Edison and it is known that the patent for the Canadian discovery was purchased by Edison when he was making his original investigations and before he obtained his patent.

The two men had patented it but did not have enough money to develop their invention, so they sold their US patent 181, 613 to Thomas Edison for US $ 5, 000 ($ US 100, 000 in 2006 dollars ).

In America, Edison had been working on copies of the original light bulb patented by Swan, trying to make them more efficient.

Thomas Edison patented a nickel – or cobalt – cadmium battery in 1902, and adapted the battery design when he introduced the nickel – iron battery to the US two years after Jungner had built one.

Edison patented a synchronization system connecting a projector and a phonograph, located behind the screen, via an assembly of three rigid shafts — a vertical one descending from each device, joined by a third running horizontally the entire length of the theater, beneath the floor.

He claimed an employee of his ( Maxim's ) had falsely patented the invention under his own name, and that Edison proved the employee's claim to be false, knowing that patent law would mean the invention would become public property, allowing Edison to manufacture the lightbulb without crediting Maxim as the true inventor.

* February 19-The phonograph is patented by Thomas Edison.

A fuse was patented by Thomas Edison in 1890 as part of his successful electric distribution system.

The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878 .< ref >

On 18 March, Friese-Greene sent a clipping of the story to Thomas Edison, whose laboratory had been developing a motion picture system known as the Kinetoscope.

It was clear that Edison originally intended to create a sound film system, which would not gain worldwide recognition until the release of " The Jazz Singer " in 1927.

* 1883 – The first electric lighting system employing overhead wires, built by Thomas Edison, begins service at Roselle, New Jersey.

The MPPC was preceded by the Edison licensing system, in effect in 1907 – 1908, on which the MPPC was modeled.

Edison sued to gain control of the patent ; however, after a federal court upheld the validity of the patent in 1907, Edison began negotiation with Biograph in May 1908 to reorganize the Edison licensing system.

The only real check on the power of the networks is Edison Carter, a crusading investigative journalist who regularly exposes the unethical practices of his own employer, and the team of allies both inside and outside the system who assist him in getting his reports to air and protecting him from the forces that wish to silence or kill him.

* 2007 – The last direct-current electrical distribution system in the United States is shut down in New York City by Con Edison.

Swan acknowledged that Edison had anticipated him, saying " Edison is entitled to more than I ... he has seen further into this subject, vastly than I, and foreseen and provided for details that I did not comprehend until I saw his system ".

While the earlier inventors had produced electric lighting in laboratory conditions, dating back to a demonstration of a glowing wire by Alessandro Volta in 1800, Edison concentrated on commercial application, and was able to sell the concept to homes and businesses by mass-producing relatively long-lasting light bulbs and creating a complete system for the generation and distribution of electricity.

It was on September 4, 1882, that Edison switched on his Pearl Street generating station's electrical power distribution system, which provided 110 volts direct current ( DC ) to 59 customers in lower Manhattan.

George Westinghouse and Edison became adversaries because of Edison's promotion of direct current ( DC ) for electric power distribution instead of the more easily transmitted alternating current ( AC ) system invented by Nikola Tesla and promoted by Westinghouse.

Despite the common belief that Edison did not use mathematics, analysis of his notebooks reveal that he was an astute user of mathematical analysis conducted by his assistants such as Francis Robbins Upton, for example, determining the critical parameters of his electric lighting system including lamp resistance by an analysis of Ohm's Law, Joule's Law and economics.

Not technically a projector system, it was a peep show machine showing a continuous loop of the film Dickson invented, lit by an Edison light source, viewed individually through the window of a cabinet housing its components.

Seeking to develop a movie projector system, they hired former Edison employee Eugene Lauste, probably at Dickson's suggestion.

The team of former Edison associates brought to fruition the Eidoloscope projector system, which would be used in the first commercial movie screening in world history on 20 May 1895.

* January 19 – The first electric lighting system employing overhead wires begins service in Roselle, New Jersey ( it was built by Thomas Edison ).

During this time, Thomas Edison was issued a British patent for a system using compressed air as an amplifying mechanism for his early cylinder phonographs, but he ultimately settled for the familiar metal horn driven by a membrane attached to the stylus.

In 1912, Commonwealth Edison developed a system of telemetry to monitor electrical loads on its power grid.

In 1911, Westinghouse received the AIEE's Edison Medal " For meritorious achievement in connection with the development of the alternating current system.

On 18 March, Friese-Greene sent a clipping of the story to Thomas Edison, whose laboratory had been developing a motion picture system known as the Kinetoscope.

* 1892 – Thomas Edison receives a patent for a two-way telegraph.

* 1876 – Thomas Edison receives a patent for his mimeograph.

Edison was awarded a patent for this invention in 1884.

Since there was no apparent practical use for such a device at the time, the patent application was most likely simply a precaution in case someone else did find a use for the so-called Edison effect.

Through such people as Nikola Tesla, Galileo Ferraris, Oliver Heaviside, Thomas Edison, Ottó Bláthy, Ányos Jedlik, Sir Charles Parsons, Joseph Swan, George Westinghouse, Ernst Werner von Siemens, Alexander Graham Bell and Lord Kelvin, electricity was turned from a scientific curiosity into an essential tool for modern life, becoming a driving force for the Second Industrial Revolution.

He received in 1942 the AIEEs Edison Medal " for distinguished contributions to the art of electric communication, notably the regenerative circuit, the superheterodyne, and frequency modulation ".

Unique among all the one minute long films made by the Edison company, which recorded parts of the acts of variety performers for their Kinetoscope viewing machines, was The Execution of Mary, Queen of Scots.

The best known of these film-makers was Edwin S. Porter, who started making films for the Edison Company in 1901.

Blair's company supplied film to Edison for five years.

In 1910, Edison Studios produced the first film version of Frankenstein, which was thought lost for many years.

Since 1902, Edison had also been notifying distributors and exhibitors that if they did not use Edison machines and films exclusively, they would be subject to litigation for supporting filmmaking that infringed Edison's patents.

Advertisement from 1889 for the Edison Mimeograph

Thomas Edison received US patent 180, 857 for " Autographic Printing " on August 8, 1876.

In 1880 Edison obtained a further patent, US 224, 665: " Method of Preparing Autographic Stencils for Printing ", which covered the making of stencils using a file plate, a grooved metal plate on which the stencil was placed which perforated the stencil when written on with a blunt metal stylus.

The only original cast retained for the U. S. version series were Matt Frewer ( Max Headroom / Edison Carter ) and Amanda Pays ( Theora Jones ); a third original cast member, W. Morgan Sheppard, joined the series as " Blank Reg " in later episodes.

Edison Carter ( Matt Frewer ) was a hard-hitting reporter for Network 23, who sometimes uncovered things that his superiors in the network would have preferred to keep private.

Edison cares about his co-workers, especially Theora Jones and Bryce Lynch, and he has a deep respect for his producer Murray ( although he rarely shows it ).

Theora was Network 23's star controller (" stolen " from the World One Network by Murray ) and, working with the network's star reporter, Edison Carter, she often helped save the day for everyone.

* In " Security Systems ", he is reluctantly forced into a temporary exile with the fugitive Edison Carter when his off-hand comment that " SS even does security for Network 23 " makes them realize, too late, the mistake they have made in trying to hack A7 from Bryce's lab.

Smith ), a streetwise pedicab driver whom Edison Carter frequently employs when looking for information about the city's underworld.

* 1877 – Thomas Edison demonstrates his phonograph for the first time.

In the 20th century the traditions of Russian opera were developed by many composers including Sergei Rachmaninoff in his works The Miserly Knight and Francesca da Rimini, Igor Stravinsky in Le Rossignol, Mavra, Oedipus rex, and The Rake's Progress, Sergei Prokofiev in The Gambler, The Love for Three Oranges, The Fiery Angel, Betrothal in a Monastery, and War and Peace ; as well as Dmitri Shostakovich in The Nose and Lady Macbeth of the Mtsensk District, Edison Denisov in L ' écume des jours, and Alfred Schnittke in Life with an Idiot and Historia von D. Johann Fausten.
