He was born on February 11, in Mt. He had trouble hearing because of an uncared for middle ear infection, and he had difficulty paying attention in school. As a result, he was pulled out of school where he was mother was then forced to home school him. At a young age, Thomas Edison created a small business where he would sell newspapers on the train, and eventually recruited some of his friends to work for him.
The most important event that influenced Thomas Edison as a teenager was when he was taught how to use a telegraph machine. One day he had saved the life of a boy from being hit by a train. In turned out that this boy was the son of the chief of the train station, and as a reward the train station chief agreed to teach Edison how to use the telegraph machine. Based on his experience with the telegraph machine, Thomas Edison later created the double telegraph. The double telegraph could send two messages and receive two messages at the same time.
Edison was eventually successful and sold this invention to a man named Mr. Goulden for thirty thousand dollars, which is equivalent to around five hundred thousand dollars today.
With this money he was able to buy a big house in Menlo Park, New Jersey with a separate laboratory. In this laboratory Edison and his partner made most of his great inventions. As Thomas Edison got older he became well known for many of his inventions. The invention that really made him famous was the phonograph. The phonograph was a device that allowed people to record and play music. The public was amazed because they never even thought someone could record their own voice and play it over and over again.
Edison was invited to Washington D. C to show his invention to congressmen, senators and the US president, Hayes. It started out small and eventually developed into something larger and more special.
Edison moved to New York City in the middle of A friend, Franklin L. When Edison managed to fix a broken machine there, he was hired to manage and improve the printer machines.
During the next period of his life, Edison became involved in multiple projects and partnerships dealing with the telegraph. In October , Edison formed with Franklin L. They advertised themselves as electrical engineers and constructors of electrical devices.
Edison received several patents for improvements to the telegraph. The partnership merged with the Gold and Stock Telegraph Co. He formed the American Telegraph Works to work on developing an automatic telegraph later in the year.
In he began to work on a multiplex telegraphic system for Western Union, ultimately developing a quadruplex telegraph, which could send two messages simultaneously in both directions. Besides other telegraph inventions, he also developed an electric pen in His personal life during this period also brought much change.
Edison's mother died in , and later that year, he married a former employee, Mary Stilwell, on Christmas Day. While Edison clearly loved his wife, their relationship was fraught with difficulties, primarily his preoccupation with work and her constant illnesses. Edison would often sleep in the lab and spent much of his time with his male colleagues. Nevertheless, their first child, Marion, was born in February , followed by a son, Thomas, Jr. Edison nicknamed the two "Dot" and "Dash," referring to telegraphic terms.
A third child, William Leslie was born in October Edison opened a new laboratory in Menlo Park, NJ, in This site later become known as an "invention factory," since they worked on several different inventions at any given time there. Edison would conduct numerous experiments to find answers to problems. He said, "I never quit until I get what I'm after.
Negative results are just what I'm after. They are just as valuable to me as positive results. In , Edison worked on a telephone transmitter that greatly improved on Alexander Graham Bell's work with the telephone. His transmitter made it possible for voices to be transmitted at higer volume and with greater clarity over standard telephone lines. Edison's experiments with the telephone and the telegraph led to his invention of the phonograph in It occurred to him that sound could be recorded as indentations on a rapidly-moving piece of paper.
He eventually formulated a machine with a tinfoil-coated cylinder and a diaphragm and needle. When Edison spoke the words "Mary had a little lamb" into the mouthpiece, to his amazement the machine played the phrase back to him. The Edison Speaking Phonograph Company was established early in to market the machine, but the initial novelty value of the phonograph wore off, and Edison turned his attention elsewhere. Edison focused on the electric light system in , setting aside the phonograph for almost a decade.
In return for handing over his patents to the company, Edison received a large share of stock. Work continued into , as the lab attempted not only to devise an incandescent bulb, but an entire electrical lighting system that could be supported in a city.
A filament of carbonized thread proved to be the key to a long-lasting light bulb. Lamps were put in the laboratory, and many journeyed out to Menlo Park to see the new discovery. A special public exhibition at the lab was given for a multitude of amazed visitors on New Year's Eve. Edison set up an electric light factory in East Newark in , and then the following year moved his family and himself to New York and set up a laboratory there.
In order to prove its viability, the first commercial electric light system was installed on Pearl Street in the financial district of Lower Manhattan in , bordering City Hall and two newspapers. Initially, only four hundred lamps were lit; a year later, there were customers using 10, lamps.
This lighting system was also taken abroad to the Paris Lighting Exposition in , the Crystal Palace in London in , the coronation of the czar in Moscow, and led to the establishment of companies in several European countries.
The success of Edison's lighting system could not deter his competitors from developing their own, different methods. Both sides attacked the limitations of each system. Edison, in particular, pointed to the use of AC current for electrocution as proof of its danger. By , the invention of a device that combined an AC induction motor with a DC dynamo offered the best performance of all, and AC current became dominant.
The Edison General Electric Co. Edison's wife, Mary, died on August 9, , possibly from a brain tumor. Edison's children from his first marriage were distanced from their father's new life, as Edison and Mina had their own family: Madeleine, born on ; Charles on ; and Theodore on Unlike Mary, who was sickly and often remained at home, and was also deferential to her husband's wishes, Mina was an active woman, devoting much time to community groups, social functions, and charities, as well as trying to improve her husband's often careless personal habits.
The facility included a machine shop, phonograph and photograph departments, a library, and ancillary buildings for metallurgy, chemistry, woodworking, and galvanometer testings. While Edison had neglected further work on the phonograph , others had moved forward to improve it. In particular, Chichester Bell and Charles Sumner Tainter developed an improved machine that used a wax cylinder and a floating stylus, which they called a graphophone. They sent representatives to Edison to discuss a possible partnership on the machine, but Edison refused to collaborate with them, feeling that the phonograph was his invention alone.
With this competition, Edison was stirred into action and resumed his work on the phonograph in Edison eventually adopted methods similar to Bell and Tainter's in his own phonograph. The phonograph was initially marketed as a business dictation machine. Lippincott acquired control of most of the phonograph companies, including Edison's, and set up the North American Phonograph Co.
The business did not prove profitable, and when Lippincott fell ill, Edison took over the management. In , the North American Phonograph Co. In , Edison started the National Phonograph Co. Over the years, Edison made improvements to the phonograph and to the cylinders which were played on them, the early ones being made of wax. Edison introduced an unbreakable cylinder record, named the Blue Amberol, at roughly the same time he entered the disc phonograph market in The introduction of an Edison disc was in reaction to the overwhelming popularity of discs on the market in contrast to cylinders.
Touted as being superior to the competition's records, the Edison discs were designed to be played only on Edison phonographs, and were cut laterally as opposed to vertically. The success of the Edison phonograph business, though, was always hampered by the company's reputation of choosing lower-quality recording acts. In the s, competition from radio caused business to sour, and the Edison disc business ceased production in Another Edison interest was an ore-milling process that would extract various metals from ore.
In , he formed the Edison Ore-Milling Co. In , he returned to the project, thinking that his process could help the mostly depleted Eastern mines compete with the Western ones. In , the New Jersey and Pennsylvania Concentrating Works was formed, and Edison became absorbed by its operations and began to spend much time away from home at the mines in Ogdensburg, New Jersey. Although he invested much money and time into this project, it proved unsuccessful when the market went down and additional sources of ore in the Midwest were found.
Edison also became involved in promoting the use of cement and formed the Edison Portland Cement Co. He tried to promote widespread use of cement for the construction of low-cost homes and envisioned alternative uses for concrete in the manufacture of phonographs, furniture, refrigerators, and pianos.
