Thomas Alva Edison lit up the world with his invention of the electric light. Without him, the Thomas A. Edison was born in Milan, Ohio, on February 11, Chemists and Chemistry that Transformed Our Lives. Thomas Edison, Chemist. Edison & Ford Winter Estates, May 25, Thomas Edison National Historical . For years I have been talking with participants in my innovation workshops around the world about the American inventor, Thomas. Edison, and recommending.

He was the seventh and last child of Samuel Ogden Edison Jr. Samuel Jr. By contrast, Samuel Jr. Once across the border, he found his way to Milan, Ohio. His patrilineal family line was Dutch by way of New Jersey; [10] the surname had originally been "Edeson. The cause of his deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle-ear infections. Around the middle of his career, Edison attributed the hearing impairment to being struck on the ears by a train conductor when his chemical laboratory in a boxcar caught fire and he was thrown off the train in Smiths Creek, Michigan , along with his apparatus and chemicals. In his later years, he modified the story to say the injury occurred when the conductor, in helping him onto a moving train, lifted him by the ears. He became a telegraph operator after he saved three-year-old Jimmie MacKenzie from being struck by a runaway train. Jimmie's father, station agent J. MacKenzie of Mount Clemens, Michigan , was so grateful that he trained Edison as a telegraph operator. He also studied qualitative analysis and conducted chemical experiments on the train until he left the job. These talents eventually led him to found 14 companies, including General Electric , still one of the largest publicly traded companies in the world. Edison requested the night shift, which allowed him plenty of time to spend at his two favorite pastimes—reading and experimenting. Eventually, the latter pre-occupation cost him his job.

Most of the work was completed in May , and the Columbia went to New York City , where Edison and his personnel installed Columbia's new lighting system. The Columbia was Edison's first commercial application for his incandescent light bulb. The Edison equipment was removed from Columbia in Latimer had received a patent in January for the "Process of Manufacturing Carbons", an improved method for the production of carbon filaments for light bulbs.

Latimer worked as an engineer, a draftsman and an expert witness in patent litigation on electric lights. Sawyer and was, therefore, invalid.

History: Thomas Alva Edison

Litigation continued for nearly six years, until October 6, , when a judge ruled that Edison's electric light improvement claim for "a filament of carbon of high resistance" was valid.

Mahen Theatre in Brno in what is now the Czech Republic , opened in , and was the first public building in the world to use Edison's electric lamps.

Francis Jehl , Edison's assistant in the invention of the lamp, supervised the installation. On September 4, , Edison switched on his Pearl Street generating station's electrical power distribution system, which provided volts direct current DC to 59 customers in lower Manhattan. The DC supply system provided electricity supplies to street lamps and several private dwellings within a short distance of the station. On January 19, , the first standardized incandescent electric lighting system employing overhead wires began service in Roselle, New Jersey.

War of currents Main article: War of Currents Extravagant displays of electric lights quickly became a feature of public events, as in this picture from the Tennessee Centennial Exposition.

As Edison expanded his direct current DC power delivery system, he received stiff competition from companies installing alternating current AC systems. From the early s AC arc lighting systems for streets and large spaces had been an expanding business in the US. With the development of transformers in Europe and by Westinghouse Electric in the US in —, it became possible to transmit AC long distances over thinner and cheaper wires, and "step down" the voltage at the destination for distribution to users.

This allowed AC to be used in street lighting and in lighting for small business and domestic customers, the market Edison's patented low voltage DC incandescent lamp system was designed to supply.

Edison's DC plants could not deliver electricity to customers more than one mile from the plant, and left a patchwork of unsupplied customers between plants.

Small cities and rural areas could not afford an Edison style system at all, leaving a large part of the market without electrical service. AC companies expanded into this gap.

Edison expressed views that AC was unworkable and the high voltages used were dangerous. As George Westinghouse installed his first AC systems in , Thomas Edison struck out personally against his chief rival stating, "Just as certain as death, Westinghouse will kill a customer within six months after he puts in a system of any size.

He has got a new thing and it will require a great deal of experimenting to get it working practically. One notion is that the inventor could not grasp the more abstract theories behind AC and was trying to avoid developing a system he did not understand. Edison also appeared to have been worried about the high voltage from misinstalled AC systems killing customers and hurting the sales of electric power systems in general.

By the end of , Edison Electric was losing market share to Westinghouse, who had built 68 AC-based power stations to Edison's DC-based stations.

This turned into a media frenzy against high voltage alternating current and the seemingly greedy and callous lighting companies that used it. Brown in a propaganda campaign, aiding Brown in the public electrocution of animals with AC, and supported legislation to control and severely limit AC installations and voltages to the point of making it an ineffective power delivery system in what was now being referred to as a "battle of currents".

The development of the electric chair was used in an attempt to portray AC as having a greater lethal potential than DC and smear Westinghouse at the same time via Edison colluding with Brown and Westinghouse's chief AC rival, the Thomson-Houston Electric Company, to make sure the first electric chair was powered by a Westinghouse AC generator.

Thomas Edison's staunch anti-AC tactics were not sitting well with his own stockholders. By the early s, Edison's company was generating much smaller profits than its AC rivals, and the War of Currents would come to an end in with Edison forced out of controlling his own company.

That year, the financier J. General Electric now controlled three-quarters of the US electrical business and would compete with Westinghouse for the AC market. Edison's work on rubber took place largely at his research laboratory in Fort Myers, which has been designated as a National Historic Chemical Landmark.

Initially, only Ford and Firestone were to contribute funds to the project while Edison did all the research. Edison did the majority of the research and planting, sending results and sample rubber residues to his West Orange Lab. Edison employed a two-part Acid-base extraction , to derive latex from the plant material after it was dried and crushed to a powder.

Edison decided on Solidago leavenworthii , also known as Leavenworth's Goldenrod. The representatives decided to give a cubic foot of solid copper weighing pounds with their gratitude inscribed on it in appreciation for his part in the "continuous stimulation in the copper industry".

The fundamental design of Edison's fluoroscope is still in use today, although Edison abandoned the project after nearly losing his own eyesight and seriously injuring his assistant, Clarence Dally. Dally made himself an enthusiastic human guinea pig for the fluoroscopy project and was exposed to a poisonous dose of radiation. He later died of injuries related to the exposure. In , a shaken Edison said: "Don't talk to me about X-rays, I am afraid of them.

His impetus for its creation was the desire to measure the heat from the solar corona during the total Solar eclipse of July 29, Telegraph improvements This section possibly contains original research.

December Learn how and when to remove this template message The key to Edison's fortunes was telegraphy. With knowledge gained from years of working as a telegraph operator, he learned the basics of electricity.

This allowed him to make his early fortune with the stock ticker , the first electricity-based broadcast system. On August 9, , Edison received a patent for a two-way telegraph. Edison was also granted a patent for the motion picture camera or "Kinetograph".

He did the electromechanical design while his employee W. Dickson , a photographer, worked on the photographic and optical development.

Much of the credit for the invention belongs to Dickson. This device was installed in penny arcades, where people could watch short, simple films. The kinetograph and kinetoscope were both first publicly exhibited May 20, Later, he exhibited motion pictures with voice soundtrack on cylinder recordings, mechanically synchronized with the film.

Maguire and Joseph D. Baucus a dozen machines. Bush placed from October 17, , the first kinetoscopes in London.

In the last three months of , the Continental Commerce Company sold hundreds of kinetoscopes in Europe i. The first kinetoscopes arrived in Belgium at the Fairs in early The main investors in this company were Belgian industrialists. The businessman Ladislas-Victor Lewitzki, living in London but active in Belgium and France, took the initiative in starting this business.

In , he also became a shareholder of the Biograph and Mutoscope Company for France. The majority of the productions were short films showing everything from acrobats to parades to fire calls including titles such as Fred Ott's Sneeze , The Kiss , The Great Train Robbery , Alice's Adventures in Wonderland , and the first Frankenstein film in In , when the owners of Luna Park, Coney Island announced they would execute Topsy the elephant by strangulation, poisoning, and electrocution with the electrocution part ultimately killing the elephant , Edison Manufacturing sent a crew to film it, releasing it that same year with the title Electrocuting an Elephant.

Play media A Day with Thomas Edison As the film business expanded, competing exhibitors routinely copied and exhibited each other's films. Many of these paper prints survived longer and in better condition than the actual films of that era. Thomas Edison was the first honorary fellow of the Acoustical Society of America , which was founded in Edison said his favorite movie was The Birth of a Nation.

He thought that talkies had "spoiled everything" for him. They concentrate on the voice now and have forgotten how to act. I can sense it more than you because I am deaf.

Edison: His Life and Inventions

High-grade iron ore was scarce on the east coast of the United States and Edison tried to mine low-grade ore. Edison developed a process using rollers and crushers that could pulverize rocks up to 10 tons. The dust was then sent between three giant magnets that would pull the iron ore from the dust.

Despite the failure of his mining company, the Edison Ore Milling Company , Edison used some of the materials and equipment to produce cement. He returned as a mining prospector and is credited with the original discovery of the Falconbridge ore body. His attempts to mine the ore body were not successful, and he abandoned his mining claim in With this company, Edison exploited his invention of the accumulator. In , people already worked for the company.

The first accumulators were produced for electric cars, but there were several defects. Several customers complained about the products. When the capital of the company was spent, Edison paid for the company with his private money. Edison did not demonstrate a mature product until a nickel-iron-battery with lye as the electrolyte.

Most chemicals were imported from Europe. The outbreak of war in August, , resulted in an immediate shortage of imported chemicals. One of particular importance to Edison was phenol , which was used to make phonograph records—presumably as phenolic resins of the Bakelite type.
