Thomas Edison

American inventor and businessman Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio, and grew up in Port Huron, Michigan. 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 taught him at home. much of his education came from reading R.G. Parker’s School of Natural Philosophy. 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 1854 Edison’s family moved to Port Huron, Michigan, He sold candy and newspapers on trains running from Port Huron to Detroit, and he sold vegetables to supplement his income. He also studied qualitative analysis, and conducted chemical experiments on the train until an unfortunate accident. He obtained the 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, which is still one of the largest publicly traded companies in the world.

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 that 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 be played only 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.” 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 which was also used in radio broadcasting and public address work through the 1920s.

He also developed many other devices that greatly influenced life around the world, including the motion picture camera, and a long-lasting, practical electric light bulb Edison also patented a system for electricity distribution in 1880, which was essential to capitalize on the invention of the electric lamp. Dubbed “The Wizard of Menlo Park” by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.Edison is the fourth most prolific inventor 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 developed a system of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world. He also developed the first power station on Pearl Street in Manhattan, New York and 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 is still in use today.

Edison was active in business Just months before his death, the Electrical transmission for the Lackawanna Railroad inaugurated suburban electric train service from Hoboken to Montclair, Dover, and Gladstone in New Jersey. was by means of an overhead catenary system using direct current, which Edison had championed. Despite his frail condition, Edison was at the throttle of the first electric MU (Multiple-Unit) train to depart Lackawanna Terminal in Hoboken in September 1930, driving the train the first mile through Hoboken yard on its way to South Orange.This fleet of cars would serve commuters in northern New Jersey for the next 54 years until their retirement in 1984. A plaque commemorating Edison’s inaugural ride can be seen today in the waiting room of Lackawanna Terminal in Hoboken, which is presently operated by New Jersey Transit.

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”. He is reported to have believed this diet would restore his health. Edison became the owner of his Milan, Ohio, birthplace in 1906. On his last visit, in 1923, he was reportedly 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. 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.

NATIONAL INVENTORS DAY

National Inventors day takes place annually on February 11 to commemorate the birth of Thomas Edison and to recognise the contributions of inventors. It was started by Former US President Ronald Reagan, who proclaimed February 11, 1983 as National Inventors’ Day, In recognition of the enormous contribution inventors make to the nation and the world, the Congress designated February 11, the anniversary of the birth of the inventor Thomas Alva Edison, who held over 1,000 patents.

Meanwhile The Inventors’ Day (German: Tag der Erfinder) in the German-speaking countries Germany, Austria and Switzerland takes place on November 9, and celebrates he birthday of the Austrian-born inventor and Hollywood actress Hedy Lamarr whose main invention was the frequency-hopped spread spectrum in 1942. The day was proclaimed by Berlin inventor and entrepreneur Gerhard Muthenthaler.

The aims of National Inventors day are to Encourage people towards their own ideas and for a change to the better and Remind people of forgotten inventors. Hungarian Inventors’ Day (Magyar Feltalálók Napja) is celebrated on June 13 in memoriam of Albert Szent-Györgyi who registered his national patent about the synthesized Vitamin C in 1941 and won the Nobel Prize in Physiology or Medicine in 1937. It is celebrated by the Association of Hungarian Inventors (MAFE) since 2009. While in the Republic of Moldova an Inventors’ and Rationalizers’ Day is celebrated annually at the end of June, Thailand celebrates Inventors’ Day on February 2 To commemorate the anniversary of His Majesty King Bhumibol Adulyadej’s allocation of a patent for a slow speed surface aerator on February 2, 1993.
