Birthplace of Thomas Edison
Historical marker of Edison's birthplace in
Milan, Ohio Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor, scientist, and businessman who developed many devices that greatly influenced life around the world, including the
phonograph, the
motion picture camera, and a long-lasting, practical electric
light bulb. Dubbed "The Wizard of Menlo Park" (now
Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of
mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.
[1]
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
Thomas Edison was born in
Milan, Ohio and grew up in
Port Huron, Michigan. He was the seventh and last child of Samuel Ogden Edison, Jr. (1804–96, born in
Marshalltown, Nova Scotia, Canada) and Nancy Matthews Elliott (1810–1871).
[2][citation needed] His father had to escape from Canada because he took part in the unsuccessful
Mackenzie Rebellion of 1837.
[citation needed] Edison considered himself to be of Dutch ancestry.
[3] In school, the young Edison's mind often wandered, and his teacher, the Reverend Engle, was overheard calling him "
addled". This ended Edison's three months of official schooling. Edison recalled later, "My mother was the making of me. She was so true, so sure of me; and I felt I had something to live for, someone I must not disappoint." His mother homeschooled him.
[4] Much of his education came from reading R.G. Parker's
School of Natural Philosophy and
The Cooper Union. Edison developed hearing problems at an early age. 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.
[5][6] Edison's family was forced to move to
Port Huron, Michigan, when the railroad bypassed Milan in 1854,
[7] but his life there was bittersweet. He sold candy and newspapers on trains running from Port Huron to Detroit, and he sold vegetables to supplement his income. This began Edison's long streak of entrepreneurial ventures as he discovered his talents as a businessman. These talents eventually led him to found 14 companies, including
General Electric, which is still in existence and is one of the largest
publicly traded companies in the world.
[8][9]
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]
Marriages and children
On December 25, 1871, Edison married 16-year-old Mary Stilwell, whom he had met two months earlier as she was an employee at one of his shops. They had three children:
- Marion Estelle Edison (1873–1965), nicknamed "Dot"[14]
- Thomas Alva Edison, Jr. (1876–1935), nicknamed "Dash"[15]
- William Leslie Edison (1878–1937) Inventor, graduate of the Sheffield Scientific School at Yale, 1900.[16]
Mary Edison died on August 9, 1884, possibly from a
brain tumor.
[17]
On February 24, 1886, at the age of thirty nine, Edison married 20-year-old Mina Miller in
Akron, Ohio.
[18] She was the daughter of inventor
Lewis Miller, co-founder of the
Chautauqua Institution and a benefactor of
Methodist charities. They also had three children:
Mina outlived Thomas Edison, dying on August 24, 1947.
[22][23]
Beginning his career
Photograph of Edison with his phonograph, taken by
Mathew Brady in 1877
Thomas Edison began his career as an inventor in
Newark, New Jersey, with the automatic repeater and his other improved telegraphic devices, but the invention which first gained him notice was the
phonograph in 1877. This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as "The Wizard of Menlo Park," New Jersey. His first phonograph recorded on
tinfoil around a grooved cylinder, but had poor
sound quality and the recordings could only be played a few times. In the 1880s, a redesigned model using wax-coated cardboard cylinders was produced by
Alexander Graham Bell,
Chichester Bell, and
Charles Tainter. This was one reason that Thomas Edison continued work on his own "Perfected Phonograph."
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.

Henry Ford Museum in Dearborn, Michigan. (Note the organ against the back wall)
William J. Hammer, a consulting electrical engineer, began his duties as a laboratory assistant to Edison in December 1879. He assisted in experiments on the telephone, phonograph, electric railway, iron ore separator,
electric lighting, and other developing inventions. However, Hammer worked primarily on the incandescent electric lamp and was put in charge of tests and records on that device. In 1880, he was appointed chief engineer of the Edison Lamp Works. In his first year, the plant under General Manager
Francis Robbins Upton turned out 50,000 lamps. According to Edison, Hammer was "a pioneer of incandescent electric lighting".
Thomas Edison's first successful light bulb model, used in public demonstration at Menlo Park, December 1879
Nearly all of Edison's patents were utility patents, which were protected for a 17-year period and included inventions or processes that are electrical, mechanical, or chemical in nature. About a dozen were
design patents, which protect an ornamental design for up to a 14-year period. As in most patents, the inventions he described were improvements over
prior art. The phonograph patent, in contrast, was unprecedented as describing the first device to record and reproduce sounds.
[24] Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light. Many earlier inventors had previously devised incandescent lamps including
Henry Woodward, and
Mathew Evans. Others who developed early and not commercially practical incandescent electric lamps included
Humphry Davy,
James Bowman Lindsay,
Moses G. Farmer,
[25] William E. Sawyer,
Joseph Swan and
Heinrich Göbel. Some of these early bulbs had such flaws as an extremely short life, high expense to produce, and high
electric current drawn, making them difficult to apply on a large scale commercially. In 1878, Edison applied the term
filament to the
element of glowing wire carrying the current, although the English inventor
Joseph Swan had used the term prior to this. Swan developed an incandescent light with a long lasting filament at about the same time as Edison, but it lacked the high resistance needed to be an effective part of an electrical utility. Edison and his co-workers set about the task of creating longer-lasting bulbs. In Britain, Joseph Swan had been able to obtain a patent on the incandescent lamp because of an oversight in the drafting of Edison's patent application.
[26] Unable to raise the required capital in Britain because of this, Edison was forced to enter into a joint venture with Swan (known as
Ediswan). 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".
[27] By 1879, Edison had produced a new concept: a high resistance lamp in a very high vacuum, which would burn for hundreds of hours. 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.
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
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]
U.S. Patent#223898: Electric-Lamp. Issued January 27, 1880.
In 1878, Edison formed the
Edison Electric Light Company in New York City with several financiers, including
J. P. Morgan and the members of the
Vanderbilt family. Edison made the first public demonstration of his incandescent light bulb on December 31, 1879, in Menlo Park. It was during this time that he said: "We will make electricity so cheap that only the rich will burn candles."
[33]
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
Edison's true success, like that of his friend
Henry Ford, was in his ability to maximize profits through establishment of mass-production systems and
intellectual property rights.
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. Unlike DC, AC could be stepped up to very high voltages with
transformers, sent over thinner and cheaper wires, and stepped down again at the destination for distribution to users.
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
Photograph of Thomas Edison by Victor Daireaux, Paris, circa 1880s
Frank J. Sprague, a competent mathematician and former
naval officer, was recruited by
Edward H. Johnson and joined the Edison organization in 1883. One of Sprague's significant contributions to the Edison Laboratory at Menlo Park was to expand Edison's mathematical methods. 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 Upton, for example, determining the critical parameters of his electric lighting system including lamp resistance by a sophisticated analysis of
Ohm's Law,
Joule's Law and economics.
[44]
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:
"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
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:
"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
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]
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.
The June 1894 Leonard–Cushing bout. Each of the six one-minute rounds recorded by the Kinetoscope was made available to exhibitors for $22.50.
[50] Customers who watched the final round saw Leonard score a knockdown.
Officially the kinetoscope entered Europe when the rich American Businessman
Irving T. Bush (1869–1948) bought from the Continental Commerce Company of Franck Z. Maguire and Joseph D. Bachus a dozen machines. Bush placed from October 17, 1894, the first kinetoscopes in London. At the same time the French company Kinétoscope Edison Michel et Alexis Werner bought these machines for the market in France. In the last three months of 1894 The Continental Commerce Company sold hundreds of kinetoscopes in Europe (i.e. the Netherlands and Italy). In Germany and in
Austria-Hungary the kinetoscope was introduced by the Deutsche-österreichische-Edison-Kinetoscop Gesellschaft, founded by the Ludwig Stollwerck
[51] of the Schokoladen-Süsswarenfabrik Stollwerck & Co of Cologne. The first kinetoscopes arrived in Belgium at the
Fairs in early 1895. The Edison's Kinétoscope Français, a Belgian company, was founded in Brussels on January 15, 1895, with the rights to sell the kinetoscopes in Monaco, France and the French colonies. The main investors in this company were Belgian industrialists. On May 14, 1895, the Edison's Kinétoscope Belge was founded in Brussels. The businessman Ladislas-Victor Lewitzki, living in London but active in Belgium and France, took the initiative in starting this business. He had contacts with
Leon Gaumont and the
American Mutoscope and Biograph Co. In 1898 he also became a shareholder of the Biograph and Mutoscope Company for France.
[52]
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)
Thomas A. Edison Industries Exhibit, Primary Battery section, 1915
Edison moved from Menlo Park after the death of Mary Stilwell and purchased a home known as "
Glenmont" in 1886 as a wedding gift for Mina in
Llewellyn Park in
West Orange, New Jersey. In 1885, Thomas Edison bought property in
Fort Myers, Florida, and built what was later called
Seminole Lodge as a winter retreat. Edison and his wife Mina spent many winters in Fort Myers where they recreated and Edison tried to find a domestic source of natural
rubber.
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.

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.
Companies bearing Edison's name
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
Thomas Edison has appeared in
popular culture as a character in novels, films, comics and video games. His prolific inventing helped make him an icon and he has made appearances in popular culture during his lifetime down to the present day. His history with
Nikola Tesla has also provided dramatic tension and is a theme returned to numerous times.
