Sir Thomas Alva Edison biography

                        Thomas Alva Edison (Arun.Noutiyal writter )

Early life


Edison as a boy at a very small age 12 years.....    arun 
Thomas Edison was born, in 1847, in Milan, Ohio, and grew up in Port Huron, Michigan. He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York). His father, the son of a Loyalist refugee, had moved as a boy with the family from Nova Scotia, settling in southwestern Ontario (then called Upper Canada), in a village known as Shewsbury, later Vienna, by 1811. Samuel Jr. eventually fled Ontario, because he took part in the unsuccessful Mackenzie Rebellion of 1837.] His father, Samuel Sr., had earlier fought in the War of 1812 as captain of the First Middlesex Regiment. By contrast, Samuel Jr.'s struggle found him on the losing side, and he crossed into the United States at Sarnia-Port Huron. Once across the border, he found his way to Milan,hio. His patrilineal family line was Dutch by way of New Jersey; the surname had originally been "Edeson."
Edison only attended school for a few months and was instead taught by his mother.[12] Much of his education came from reading R.G. Parker's School of Natural Philosophy and The Cooper Union for the Advancement of Science and Art.

Early career


Edison's family moved to Port Huron, Michigan, after the canal owners successfully kept the railroad out of Milan Ohio in 1854 and business declined.Edison sold candy and newspapers on trains running from Port Huron to Detroit, and sold vegetables. 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. 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.[17] He was held responsible for a near collision. He also studied qualitative analysis and conducted chemical experiments on the train until he left the job.
Edison obtained the exclusive right to sell newspapers on the road, and, with the aid of four assistants, he set in type and printed the Grand Trunk Herald, which he sold with his other papers. 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, still one of the largest publicly traded companies in the world.

Menlo Park laboratory (1876–1886)

Edison's major innovation was the establishment of an industrial research lab in 1876. It was built in Menlo Park, a part of Raritan Township (now named Edison Township in his honor) in Middlesex County, New Jersey, 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 ($216,600 in today's dollars.[24]), which he gratefully accepted.[25] 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

Phonograph ( edision invention)

Edison began his career as an inventor in Newark, New Jersey, with the automatic repeater and his other improved telegraphic devices, but the invention that first gained him wider 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. Despite its limited sound quality and that the recordings could be played only a few times, the phonograph made Edison a celebrity. Joseph Henry, president of the National Academy of Sciences and one of the most renowned electrical scientists in the US, described Edison as "the most ingenious inventor in this country... or in any other".In April 1878, Edison traveled to Washington to demonstrate the phonograph before the National Academy of Sciences, Congressmen, Senators and US President Hayes. The Washington Post described Edison as a "genius" and his presentation as "a scene... that will live in history". Although Edison obtained a patent for the phonograph in 1878, he did little to develop it until Alexander Graham BellChichester Bell, and Charles Tainter produced a phonograph-like device in the 1880s that used wax-coatedcardboard cylinders/


Electric light

In 1878, Edison began working on a system of electrical illumination, something he hoped could compete with gas and oil based lighting.[] He began by tackling the problem of creating a long-lasting incandescent lamp, something that would be needed for indoor use. Many earlier inventors had previously devised incandescent lamps, including Alessandro Volta's demonstration of a glowing wire in 1800 and inventions by Henry Woodward and Mathew Evans. Others who developed early and commercially impractical incandescent electric lamps included Humphry DavyJames Bowman LindsayMoses G. FarmerWilliam E. SawyerJoseph 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.[ Edison realized that to connect a series of electric lights to an economically manageable size and using the necessary thickness of copper wire, he would have to develop a lamp that used a low amount of current. This lamp must have high resistance and use relatively low voltage (around 110 volts).

Electric power distribution

After devising a commercially viable electric light bulb on October 21, 1879, Edison developed an electric "utility" to compete with the existing gas light utilities. On December 17, 1880, he founded the Edison Illuminating Company, and during the 1880s, he patented a system for electricity distribution. The company established the first investor-owned electric utility in 1882 on Pearl Street Station, New York City. On September 4, 1882, 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.
In January 1882, Edison 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

As Edison expanded his direct current (DC) power delivery system, he received stiff competition from companies installing alternating current (AC) systems. From the early 1880s 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 1885–1886, 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 empire suffered from one of its chief drawbacks: it was suitable only for the high density of customers found in large cities. 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.

Battery

The Edison Storage Battery Company was founded in 1901. With this company, Edison exploited his invention of the accumulator. In 1904, 450 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 1910: a nickel-iron-battery with lye as the electrolyte.


Death

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. Rev. Stephen J. Herben officiated at the funeral;Edison is buried behind the home.
Edison's last breath is reportedly contained in a test tube at The Henry Ford museum near Detroit. 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 and casts of Edison's hands were also made.Mina died in 1947. 
                          

                                              EDISION ALWAYS SAYS 


                  NEVER GIVE UP They say that do not be afraid of mistakes, it is from man. We need to   

                                      correct those mistakes
