Edison is considered one of the most prolific inventors in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures. His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison originated the concept and implementation of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world. His first power station was on Manhattan Island, New York.
Early life
Telegrapher
Edison 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.U. MacKenzie of Mount Clemens, Michigan, was so grateful that he trained Edison as a telegraph operator. Edison's first telegraphy job away from Port Huron was at Stratford Junction, Ontario, on the Grand Trunk Railway.[10] In 1866, at the age of 19, Thomas Edison moved to Louisville, Kentucky, where, as an employee of Western Union, he worked the Associated Press bureau news wire. 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. One night in 1867, he was working with a lead-acid battery when he spilled sulfuric acid onto the floor. It ran between the floorboards and onto his boss's desk below. The next morning Edison was fired.[11]One of his mentors during those early years was a fellow telegrapher and inventor named Franklin Leonard Pope, who allowed the impoverished youth to live and work in the basement of his Elizabeth, New Jersey home. Some of Edison's earliest inventions were related to telegraphy, including a stock ticker. His first patent was for the electric vote recorder, (U. S. Patent 90,646),[12] which was granted on June 1, 1869.[13]

Menlo Park (1876–1881)
Edison's major innovation was the first industrial research lab, which was built in Menlo Park, New Jersey. It was built with the funds from the sale of Edison's quadruplex telegraph. After his demonstration of the telegraph, Edison was not sure that his original plan to sell it for $4,000 to $5,000 was right, so he asked Western Union to make a bid. He was surprised to hear them offer $10,000,[citation needed] which he gratefully accepted. The quadruplex telegraph was Edison's first big financial success, and Menlo Park became the first institution set up with the specific purpose of producing constant technological innovation and improvement. Edison was legally attributed with most of the inventions produced there, though many employees carried out research and development under his direction. His staff was generally told to carry out his directions in conducting research, and he drove them hard to produce results.
In just over a decade Edison's Menlo Park laboratory had expanded to occupy two city blocks. Edison said he wanted the lab to have "a stock of almost every conceivable material". A newspaper article printed in 1887 reveals the seriousness of his claim, stating the lab contained "eight thousand kinds of chemicals, every kind of screw made, every size of needle, every kind of cord or wire, hair of humans, horses, hogs, cows, rabbits, goats, minx, camels ... silk in every texture, cocoons, various kinds of hoofs, shark's teeth, deer horns, tortoise shell ... cork, resin, varnish and oil, ostrich feathers, a peacock's tail, jet, amber, rubber, all ores ..." and the list goes on.[28]
Over his desk, Edison displayed a placard with Sir Joshua Reynolds' famous quote: "There is no expedient to which a man will not resort to avoid the real labor of thinking."[29] This slogan was reputedly posted at several other locations throughout the facility.
With Menlo Park, Edison had created the first industrial laboratory concerned with creating knowledge and then controlling its application.
Carbon telephone transmitter
In 1877–78, Edison invented and developed the carbon microphone used in all telephones along with the Bell receiver until the 1980s. After protracted patent litigation, in 1892 a federal court ruled that Edison—and not Emile Berliner—was the inventor of the carbon microphone. The carbon microphone was also used in radio broadcasting and public address work through the 1920s.Electric light
Main article: History of the light bulb
Building on the contributions of other developers over the previous three quarters of a century, Edison made significant improvements to the idea of incandescent light, and wound up in the public consciousness as "the inventor" of the lightbulb.After many experiments with platinum and other metal filaments, Edison returned to a carbon filament. The first successful test was on October 22, 1879;[30] it lasted 40 hours. Edison continued to improve this design and by November 4, 1879, filed for U.S. patent 223,898 (granted on January 27, 1880) for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires".[31] Although the patent described several ways of creating the carbon filament including "cotton and linen thread, wood splints, papers coiled in various ways",[31] it was not until several months after the patent was granted that Edison and his team discovered a carbonized bamboo filament that could last over 1,200 hours. The idea of using this particular raw material originated from Edison's recalling his examination of a few threads from a bamboo fishing pole while relaxing on the shore of Battle Lake in the present-day state of Wyoming, where he and other members of a scientific team had traveled so that they could clearly observe a total eclipse of the sun on July 29, 1878, from the Continental Divide.[32]
George Westinghouse's company bought Philip Diehl's competing induction lamp patent rights (1882) for $25,000, forcing the holders of the Edison patent to charge a more reasonable rate for the use of the Edison patent rights and lowering the price of the electric lamp.[34]
On October 8, 1883, the US patent office ruled that Edison's patent was based on the work of William Sawyer and was therefore invalid. Litigation continued for nearly six years, until October 6, 1889, when a judge ruled that Edison's electric light improvement claim for "a filament of carbon of high resistance" was valid. To avoid a possible court battle with Joseph Swan, whose British patent had been awarded a year before Edison's, he and Swan formed a joint company called Ediswan to manufacture and market the invention in Britain.
Mahen Theatre in Brno in what is now the Czech Republic, was the first public building in the world to use Edison's electric lamps, with the installation supervised by Edison's assistant in the invention of the lamp, Francis Jehl.[35] In September 2010, a sculpture of three giant light bulbs was erected in Brno, in front of the theatre.[36]
Electric power distribution
Edison patented a system for electricity distribution in 1880, which was essential to capitalize on the invention of the electric lamp. On December 17, 1880, Edison founded the Edison Illuminating Company. The company established the first investor-owned electric utility in 1882 on Pearl Street Station, New York City. 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.[37]Earlier in the year, in January 1882 he had switched on the first steam generating power station at Holborn Viaduct in London. The DC supply system provided electricity supplies to street lamps and several private dwellings within a short distance of the station. On January 19, 1883, the first standardized incandescent electric lighting system employing overhead wires began service in Roselle, New Jersey.
War of currents
Main article: War of Currents
In 1887 there were 121 Edison power stations in the United States delivering DC electricity to customers. When the limitations of DC were discussed by the public, Edison launched a propaganda campaign to convince people that AC was far too dangerous to use. The problem with DC was that the power plants could economically deliver DC electricity only to customers within about one and a half miles (about 2.4 km) from the generating station, so that it was suitable only for central business districts. When George Westinghouse suggested using high-voltage AC instead, as it could carry electricity hundreds of miles with marginal loss of power, Edison waged a "War of Currents" to prevent AC from being adopted.
Despite Edison's contempt for capital punishment, the war against AC led him to become involved in the development and promotion of the electric chair (using AC) as an attempt to portray AC to have greater lethal potential than DC. Edison went on to carry out a brief but intense campaign to ban the use of AC or to limit the allowable voltage for safety purposes. As part of this campaign, Edison's employees publicly electrocuted animals to demonstrate the dangers of AC;[38][39] alternating electric currents are slightly more dangerous in that frequencies near 60 Hz have a markedly greater potential for inducing fatal "cardiac fibrillation" than do direct currents.[40] On one of the more notable occasions, in 1903, Edison's workers electrocuted Topsy the elephant at Luna Park, near Coney Island, after she had killed several men and her owners wanted her put to death.[41] His company filmed the electrocution.
AC replaced DC in most instances of generation and power distribution, enormously extending the range and improving the efficiency of power distribution. Though widespread use of DC ultimately lost favor for distribution, it exists today primarily in long-distance high-voltage direct current (HVDC) transmission systems. Low voltage DC distribution continued to be used in high-density downtown areas for many years but was eventually replaced by AC low-voltage network distribution in many of them. DC had the advantage that large battery banks could maintain continuous power through brief interruptions of the electric supply from generators and the transmission system. Utilities such as Commonwealth Edison in Chicago had rotary converters or motor-generator sets, which could change DC to AC and AC to various frequencies in the early to mid-20th century. Utilities supplied rectifiers to convert the low voltage AC to DC for such DC loads as elevators, fans and pumps. There were still 1,600 DC customers in downtown New York City as of 2005, and service was finally discontinued only on November 14, 2007.[42] Most subway systems still are powered by direct current.
Fluoroscopy
Edison is credited with designing and producing the first commercially available fluoroscope, a machine that uses X-rays to take radiographs. Until Edison discovered that calcium tungstate fluoroscopy screens produced brighter images than the barium platinocyanide screens originally used by Wilhelm Röntgen, the technology was capable of producing only very faint images. The fundamental design of Edison's fluoroscope is still in use today, despite the fact that Edison himself abandoned the project after nearly losing his own eyesight and seriously injuring his assistant, Clarence Dally. Dally had made himself an enthusiastic human guinea pig for the fluoroscopy project and in the process been exposed to a poisonous dose of radiation. He later died of injuries related to the exposure. In 1903, a shaken Edison said "Don't talk to me about X-rays, I am afraid of them."[43]Work relations
Another of Edison's assistants was Nikola Tesla, to whom Edison promised $50,000 if he succeeded in making improvements to his DC generation plants. Several months later, when Tesla had finished the work and asked to be paid, Edison said, "When you become a full-fledged American you will appreciate an American joke."[45] Tesla immediately resigned. With Tesla's salary of $18 per week, the payment would have amounted to over 53 years' pay and the amount was equal to the initial capital of the company. Tesla resigned when he was refused a raise to $25 per week.[46] Although Tesla accepted an Edison Medal later in life, this and other negative series of events concerning Edison remained with Tesla. The day after Edison died, the New York Times contained extensive coverage of Edison's life, with the only negative opinion coming from Tesla who was quoted as saying:
It seems very likely that Tesla's description was accurate, considering one of Edison's famous quotes regarding his attempts to make the light globe:"He had no hobby, cared for no sort of amusement of any kind and lived in utter disregard of the most elementary rules of hygiene. [...] His method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90% of the labour. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor's instinct and practical American sense."—Nikola Tesla
When Edison was a very old man and close to death, he said, in looking back, that the biggest mistake he had made was that he never respected Tesla or his work.[48]"If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward".[47]—Thomas Edison
There were 28 men recognized as Edison Pioneers.
Media inventions
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. Edison patented the sound recording and reproducing phonograph in 1878. Edison was also granted a patent for the motion picture camera or "Kinetograph". He did the electromechanical design, while his employee W.K.L. Dickson, a photographer, worked on the photographic and optical development. Much of the credit for the invention belongs to Dickson.[30] In 1891, Thomas Edison built a Kinetoscope, or peep-hole viewer. 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, 1891.[49]On August 9, 1892, Edison received a patent for a two-way telegraph. In April 1896, Thomas Armat's Vitascope, manufactured by the Edison factory and marketed in Edison's name, was used to project motion pictures in public screenings in New York City. Later he exhibited motion pictures with voice soundtrack on cylinder recordings, mechanically synchronized with the film.
In 1901, he visited the Sudbury area in Ontario, Canada, as a mining prospector, and is credited with the original discovery of the Falconbridge ore body. His attempts to actually mine the ore body were not successful, however, and he abandoned his mining claim in 1903.[53] A street in Falconbridge, as well as the Edison Building, which served as the head office of Falconbridge Mines, are named for him.
In 1902, agents of Thomas Edison bribed a theater owner in London for a copy of A Trip to the Moon by Georges Méliès. Edison then made hundreds of copies and showed them in New York City. Méliès received no compensation. He was counting on taking the film to the US and recapture its huge cost by showing it throughout the country when he realized it had already been shown there by Edison. This effectively bankrupted Méliès.[54] Other exhibitors similarly routinely copied and exhibited each others films.[55] To better protect the copyrights on his films, Edison deposited prints of them on long strips of photographic paper with the U.S. copyright office. Many of these paper prints survived longer and in better condition than the actual films of that era.[56]
Edison's favourite movie was The Birth of a Nation. He thought that talkies had "spoiled everything" for him. "There isn't any good acting on the screen. They concentrate on the voice now and have forgotten how to act. I can sense it more than you because I am deaf."[57] His favorite stars were Mary Pickford and Clara Bow.[58]
In 1908, Edison started the Motion Picture Patents Company, which was a conglomerate of nine major film studios (commonly known as the Edison Trust). Thomas Edison was the first honorary fellow of the Acoustical Society of America, which was founded in 1929.
West Orange and Fort Myers (1886–1931)
Henry Ford, the automobile magnate, later lived a few hundred feet away from Edison at his winter retreat in Fort Myers, Florida. Edison even contributed technology to the automobile. They were friends until Edison's death.
In 1928, Edison joined the Fort Myers Civitan Club. He believed strongly in the organization, writing that "The Civitan Club is doing things —big things— for the community, state, and nation, and I certainly consider it an honor to be numbered in its ranks."[59] He was an active member in the club until his death, sometimes bringing Henry Ford to the club's meetings.
The final years
Edison was active in business right up to the end. Just months before his death in 1931, the Lackawanna Railroad implemented electric trains in suburban service from Hoboken to Gladstone, Montclair and Dover in New Jersey. Transmission was by means of an overhead catenary system, with the entire project under Edison's guidance. To the surprise of many, he was at the throttle of the very first MU (Multiple-Unit) train to depart Lackawanna Terminal in Hoboken, driving the train all the way to Dover. As another tribute to his lasting legacy, the same fleet of cars Edison deployed on the Lackawanna in 1931 served commuters until their retirement in 1984, when some of them were purchased by the Berkshire Scenic Railway Museum in Lenox, Massachusetts. A special plaque commemorating the joint achievement of both the railway and Edison can be seen today in the waiting room of Lackawanna Terminal in Hoboken, presently operated by New Jersey Transit.[60]Edison was said to have been influenced by a popular fad diet in his last few years; "the only liquid he consumed was a pint of milk every three hours".[30] He is reported to have believed this diet would restore his health. However, this tale is doubtful. In 1930, the year before Edison died, Mina said in an interview about him that "Correct eating is one of his greatest hobbies." She also said that during one of his periodic "great scientific adventures", Edison would be up at 7:00, have breakfast at 8:00, and be rarely home for lunch or dinner, implying that he continued to have all three.[57]
Edison became the owner of his Milan, Ohio, birthplace in 1906. On his last visit, in 1923, he was shocked to find his old home still lit by lamps and candles.
Thomas Edison died of complications of diabetes on October 18, 1931, in his home, "Glenmont" in Llewellyn Park in West Orange, New Jersey, which he had purchased in 1886 as a wedding gift for Mina. He is buried behind the home.[61][62]
Edison's last breath is reportedly contained in a test tube at the Henry Ford Museum. Ford reportedly convinced Charles Edison to seal a test tube of air in the inventor's room shortly after his death, as a memento. A plaster death mask was also made.[63]
Mina died in 1947.
Views on politics, religion and metaphysics
Historian Paul Israel has characterized Edison as a "freethinker".[30] Edison was heavily influenced by Thomas Paine's The Age of Reason.[30] Edison defended Paine's "scientific deism", saying, "He has been called an atheist, but atheist he was not. Paine believed in a supreme intelligence, as representing the idea which other men often express by the name of deity."[30] In an October 2, 1910, interview in the New York Times Magazine, Edison stated:Nature is what we know. We do not know the gods of religions. And nature is not kind, or merciful, or loving. If God made me — the fabled God of the three qualities of which I spoke: mercy, kindness, love — He also made the fish I catch and eat. And where do His mercy, kindness, and love for that fish come in? No; nature made us — nature did it all — not the gods of the religions.[64]Edison was called an atheist for those remarks, and although he did not allow himself to be drawn into the controversy publicly, he clarified himself in a private letter: "You have misunderstood the whole article, because you jumped to the conclusion that it denies the existence of God. There is no such denial, what you call God I call Nature, the Supreme intelligence that rules matter. All the article states is that it is doubtful in my opinion if our intelligence or soul or whatever one may call it lives hereafter as an entity or disperses back again from whence it came, scattered amongst the cells of which we are made."[30]
Nonviolence was key to Edison's moral views, and when asked to serve as a naval consultant for World War I, he specified he would work only on defensive weapons and later noted, "I am proud of the fact that I never invented weapons to kill." Edison's philosophy of nonviolence extended to animals as well, about which he stated: "Nonviolence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages."[65] However, he is also notorious for having electrocuted a number of dogs in 1888, both by direct and alternating current, in an attempt to argue that the former (which he had a vested business interest in promoting) was safer than the latter (favored by his rival George Westinghouse).[66] Edison's success in promoting direct current as less lethal also led to alternating current being used in the electric chair adopted by New York in 1889 as a supposedly humane execution method; because Westinghouse was angered by the decision, he funded Eighth Amendment-based appeals for inmates set to die in the electric chair, ultimately resulting in Edison providing the generators which powered early electrocutions and testifying successfully on behalf of the state that electrocution was a painless method of execution.[67]
Tributes
Places named for Edison
Several places have been named after Edison, most notably the town of Edison, New Jersey. Thomas Edison State College, a nationally known college for adult learners, is in Trenton, New Jersey. Two community colleges are named for him: Edison State College in Fort Myers, Florida, and Edison Community College in Piqua, Ohio.[68] There are numerous high schools named after Edison; see Edison High School.The City Hotel, in Sunbury, Pennsylvania, was the first building to be lit with Edison's three-wire system. The hotel was re-named The Hotel Edison, and retains that name today.
Three bridges around the United States have been named in his honor (see Edison Bridge).
Museums and memorials
In West Orange, New Jersey, the 13.5 acre (5.5 ha) Glenmont estate is maintained and operated by the National Park Service as the Edison National Historic Site.[69] The Thomas Alva Edison Memorial Tower and Museum is in the town of Edison, New Jersey.[70] In Beaumont, Texas, there is an Edison Museum, though Edison never visited there.[citation needed] The Port Huron Museum, in Port Huron, Michigan, restored the original depot that Thomas Edison worked out of as a young newsbutcher. The depot has been named the Thomas Edison Depot Museum.[71] The town has many Edison historical landmarks, including the graves of Edison's parents, and a monument along the St. Clair River. Edison's influence can be seen throughout this city of 32,000. In Detroit, the Edison Memorial Fountain in Grand Circus Park was created to honor his achievements. The limestone fountain was dedicated October 21, 1929, the fiftieth anniversary of the creation of the lightbulb.[72] On the same night, The Edison Institute was dedicated in nearby Dearborn.In early 2010, Edison was proposed by the Ohio Historical Society as a finalist in a statewide vote for inclusion in Statuary Hall at the United States Capitol.

Awards named in honor of Edison
The Edison Medal was created on February 11, 1904, by a group of Edison's friends and associates. Four years later the American Institute of Electrical Engineers (AIEE), later IEEE, entered into an agreement with the group to present the medal as its highest award. The first medal was presented in 1909 to Elihu Thomson and, in a twist of fate, was awarded to Nikola Tesla in 1917. It is the oldest award in the area of electrical and electronics engineering, and is presented annually "for a career of meritorious achievement in electrical science, electrical engineering or the electrical arts."In the Netherlands, the major music awards are named the Edison Award after him.
The American Society of Mechanical Engineers concedes the Thomas A. Edison Patent Award to individual patents since 2000.[73]
Honors and awards given to Edison
The President of the Third French Republic, Jules Grévy, on the recommendation of his Minister of Foreign Affairs Jules Barthélemy-Saint-Hilaire and with the presentations of the Minister of Posts and Telegraphs Louis Cochery, designated Edison with the distinction of an 'Officer of the Legion of Honour' (Légion d'honneur) by decree on November 10, 1881;[74]In 1983, the United States Congress, pursuant to Senate Joint Resolution 140 (Public Law 97—198), designated February 11, Edison's birthday, as National Inventor's Day.
In 1887, Edison won the Matteucci Medal. In 1890, he was elected a member of the Royal Swedish Academy of Sciences.
In 1889, Edison was awarded the John Scott Medal.
In 1899, Edison was awarded the Edward Longstreth Medal.
Edison was awarded Franklin Medal of The Franklin Institute in 1915 for discoveries contributing to the foundation of industries and the well-being of the human race.
Edison was ranked thirty-fifth on Michael H. Hart's 1978 book The 100, a list of the most influential figures in history. Life magazine (USA), in a special double issue in 1997, placed Edison first in the list of the "100 Most Important People in the Last 1000 Years", noting that the light bulb he promoted "lit up the world". In the 2005 television series The Greatest American, he was voted by viewers as the fifteenth-greatest.
In 2008, Edison was inducted in the New Jersey Hall of Fame.
Other items named after Edison
The United States Navy named the USS Edison (DD-439), a Gleaves class destroyer, in his honor in 1940. The ship was decommissioned a few months after the end of World War II. In 1962, the Navy commissioned USS Thomas A. Edison (SSBN-610), a fleet ballistic missile nuclear-powered submarine. Decommissioned on December 1, 1983, Thomas A. Edison was stricken from the Naval Vessel Register on April 30, 1986. She went through the Navy's Nuclear Powered Ship and Submarine Recycling Program at Bremerton, Washington, beginning on October 1, 1996. When she finished the program on December 1, 1997, she ceased to exist as a complete ship and was listed as scrapped.In popular culture
