Thomas edison light bulb

Thomas Edison’s Early Life Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He was the seventh and last child born to Samuel Edison Jr. and Nancy Elliott Edison, and would be one of four to survive to adulthood. At age 12, he developed hearing loss—he was reportedly deaf in one ear, and nearly deaf in the other—which was variously attributed to scarlet fever, mastoiditis or a blow to the head. Thomas Edison received little formal education, and left school in 1859 to begin working on the railroad between Detroit and Port Huron, Michigan, where his family then lived. By selling food and newspapers to train passengers, he was able to net about $50 profit each week, a substantial income at the time—especially for a 13-year-old. Did you know? By the time he died at age 84 on October 18, 1931, Thomas Edison had amassed a record 1,093 patents: 389 for electric light and power, 195 for the phonograph, 150 for the telegraph, 141 for storage batteries and 34 for the telephone. During the To address this problem, Edison began to work on inventing devices that would help make things possible for him despite his deafness (including a printer that would convert electrical telegraph signals to letters). In early 1869, he quit telegraphy to pursue invention full time. Edison in Menlo Park From 1870 to 1875, Edison worked out of Newark, New Jersey, where he developed telegraph-related products for both Western Union Telegraph Company (then the industry leader) and its riv...

(1847-1931) Who Was Thomas Edison? Thomas Edison was an American inventor who is considered one of America's leading businessmen and innovators. Edison rose from humble beginnings to work as an inventor of major technology, including the first commercially viable incandescent light bulb. He is credited today for helping to build America's economy during the Early Life and Education Edison was born on February 11, 1847, in Milan, Ohio. He was the youngest of seven children of Samuel and Nancy Edison. His father was an exiled political activist from Canada, while his mother was an accomplished school teacher and a major influence in Edison’s early life. An early bout with scarlet fever as well as ear infections left Edison with hearing difficulties in both ears as a child and nearly deaf as an adult. Edison would later recount, with variations on the story, that he lost his hearing due to a train incident in which his ears were injured. But others have tended to discount this as the sole cause of his hearing loss. In 1854, Edison’s family moved to Port Huron, Michigan, where he attended public school for a total of 12 weeks. A hyperactive child, prone to distraction, he was deemed "difficult" by his teacher. His mother quickly pulled him from school and taught him at home. At age 11, he showed a voracious appetite for knowledge, reading books on a wide range of subjects. In this wide-open curriculum Edison developed a process for self-education and learning independently tha...

If time-travel were possible and I could pick a moment, I'd choose Menlo Park, New Jersey, for my destination on New Year's Eve in 1879. As a historian of technology, I am fascinated when an inventor takes a simple, widely understood principle and, through ingenuity and persistence, creates a practical device. As a curator, I am constantly looking for technical objects that help me understand an inventor's process. Sometimes the two of these come together, as with Edison's light bulb. The knowledge that hot materials can produce useful light is as old as the discovery of a means to control fire. In the 19th century, several people considered how this might be done electrically in the home. But it was Thomas Edison who, after more than a year of experimentation, came up with a commercially viable solution. Being a promoter as well as an inventor, he announced this achievement by lighting up his Menlo Park laboratory and adjacent buildings 135 years ago this evening. The world came to see—by carriage, by horseback, and by special trains from New York some 20 miles away. It was a fitting demonstration for the beginning of a new era. Edison's light bulb was not a simple invention. The glowing element had to be strong and to glow without burning or breaking. It had to conduct electricity, yet it also had to have a high electrical resistance; this last condition was a critical factor that only Edison, among the early inventors, understood. With a high resistance, heat would buil...

Alessandro Volta (1745-1827) Italian physicist. The Voltaic pile (wet battery) is the left object in front of him © Universal History Archive/Getty Images Thanks to the light it emitted in its copper wire, the voltaic pile could be considered one of the earliest forms of incandescent lighting. Humphry Davy in 1802 used the voltaic pile (connected them to charcoal electrodes) to create the ‘electric arc lamp’. Who really invented the light bulb? It’s easy to say that either Joseph Swan or Thomas Edison invented the light bulb, but in reality they developed upon pre-existing work that dates back to the turn of the 19th Century. Alessandro Volta, Humphrey Davy, James Bowman Lindsay, Warren de la Rue and William Staite all played a role. Thomas Edison solved many of the electric lamp’s earliest problems by experimenting with the work done by others before him. He discovered the best mixture of thin carbon filament design and employed the use of better vacuum pump technology to make him the first person to develop a truly commercially-viable light bulb.

His nemesis and former boss, Thomas Edison, was the iconic American inventor of the light bulb, the phonograph and the moving picture. The two feuding geniuses waged a "War of Currents" in the 1880s over whose electrical system would power the world — Tesla's alternating-current (AC) system or Edison's rival direct-current (DC) electric power. From their starkly different personalities to their lasting legacies, here's how the two dueling inventors stack up. Who was the most brilliant? Tesla had an "He really worked out his inventions in his imagination," Carlson told Live Science. In contrast, Edison was more of a sketcher and a tinkerer. "If you were going to [the] laboratory and watch him at work, you'd find he'd have stuff all over the bench: wires and coils and various parts of inventions," Carlson said.

In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile. Made of alternating discs of zinc and copper— interspersed with layers of cardboard soaked in salt water — the pile conducted electricity when a copper wire was connected at either end. Volta's glowing copper wire is officially considered a precursor to the battery, but is also one of the earliest manifestations of incandescent lighting. According to Harold H Schobert (" Energy and Society: An Introduction," CRC Press, 2014) the Voltaic Pile "made it possible for scientists to experiment with electric currents under controlled conditions" and furthered experiments with electricity. Not long after Volta presented his discovery of a continuous source of electricity to the Royal Society in London, Davy produced the world's first electric lamp by connecting voltaic piles to charcoal electrodes. Davy's 1802 invention was known as an electric arc lamp, named for the bright arc of...
