Who invented bulb

(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...

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.

Everyone knows the father of the light bulb — Thomas Edison. In school we learn about him and all of his accomplishments, and he’s often remembered as the greatest inventor in American history. There’s a whole unit in school where Americans learn about Edison, but barely mentioned — and quickly forgotten — is Nikola Tesla. In recent years, we hear the name Tesla all of the time, though most people associate it with the car company ran by Elon Musk. Before it was the name of a successful electric car company, it was the name of brilliant man who made electricity for the masses a reality. We are taught that this was actually the work of Edison, and he certainly played a role in the story, but we are missing a few key points where Tesla came into play. In reality, both men were accomplished inventors and visionaries, but they were also contemporaries and bitter rivals, both personally and scientifically. Before we get into detail on their feud, it’s important to look at each man individually. They each led interesting lives that shaped the turn of the century. The youngest of seven children, Thomas Edison was born in 1847 in Milan Ohio. After only 12 weeks in public school, his teacher deemed him too difficult, so he was homeschooled by his mother. By age 11, he showed an intense interest in learning a variety of things, and eventually began teaching himself. He showed business savvy by the age of 12 when he started selling his own newspapers to passengers on trains. It would...

There were ideas long before there were light bulbs. But, of all the ideas that have ever turned into inventions, only the light bulb became a symbol of ideas. Earlier innovations had literalized the experience of “seeing the light,” but no one went around talking about torchlight moments or sketching candles into cartoon thought bubbles. What made the light bulb such an irresistible image for ideas was not just the invention but its inventor. Thomas Edison was already well known by the time he perfected the long-burning incandescent light bulb, but he was photographed next to one of them so often that the public came to associate the bulbs with invention itself. That made sense, by a kind of transitive property of ingenuity: during his lifetime, Edison patented a record-setting one thousand and ninety-three different inventions. On a single day in 1888, he wrote down a hundred and twelve ideas; averaged across his adult life, he patented something roughly every eleven days. There was the light bulb and the phonograph, of course, but also the kinetoscope, the dictating machine, the alkaline battery, and the electric meter. Plus: a sap extractor, a talking doll, the world’s largest rock crusher, an electric pen, a fruit preserver, and a tornado-proof house. Not all these inventions worked or made money. Edison never got anywhere with his ink for the blind, whatever that was meant to be; his concrete furniture, though durable, was doomed; and his failed innovations in mining...

When Latimer was 10, his mother decided to split the family after the [ clarification needed] This caused Lewis's father, George Latimer, to flee for his family's safety because he had nothing to prove he was free from enslavement. So, he fled to protect his family. After his father had to flee and his mother had to split the family, Lewis and his brothers were sent to a farm school, and his sisters were sent to stay with a family friend. Lewis Howard Latimer joined the Massasoit. After receiving an honorable discharge from the U.S. Navy on July 3, 1865, he gained employment as an office boy with a Crosby Halstead and Gould, with a $3.00 per week salary.

Holonyak wasn't trying to create a light that would replace incandescent bulbs. He was trying to make a laser. In that video, just before he shows off the LED, he talks about his job, doing exploratory work—making "devices that didn't exist until we made them." (Sounds like fun, right?) One device that did not exist was a semiconductor laser. Other GE scientists were working on creating an infrared semiconductor laser; so Holonyak decided he would make a visible one. (The thinking being: "If they can make a laser, I can make a better laser than any of them.") Holonyak wasn't quite fast enough to make the first semiconductor laser—the infrared one came into being a few weeks before his. In that process, though, he did create that little semiconductor light. It was red, a signature of gallium arsenide phosphide (GaAsP), the alloy Holonyak had layered into the diode. Scientists had known since the beginning of the 20th century that certain semiconductors, when electrical current was applied, would light up. But this was the first time anyone had turned that knowledge into a practical lamp. Within the year, Holonyak had an instinct, all the way back at the beginning of the LED's history, that these little, efficient sources of light could replace the clunky incandescent bulbs that illuminated the world back then. He did not, Now LEDs are straight-up replacing incandescent light bulbs. There's another great moment at the end of that GE video, when Holonyak's handling GE's 100-w...

Arguably one of the most famous inventors of all time, Thomas Edison is credited with inventing the first commercially viable incandescent lightbulb. But this was just one of his many inventions. He’s also the inventor of the Universal Stock Printer, which was used to synchronize stock tickers’ transactions, the quadruplex telegraph, and the phonograph, among others. During his lifetime, he was granted more than 1,000 U.S. patents for various inventions. 💡 If you’ve ever used a Miracle Mop, you have Joy Mangano to thank. The 67-year-old created the innovative cleaning tool in 1990, which she marketed and sold herself. A couple of years after inventing the device, she appeared on QVC to sell it, where more than 18,000 mops were sold within a half hour. In addition to the Miracle Mop, Mangano is the creator of Rolykit, Huggable Hangers, and Forever Fragrant. Along with Steve Wozniak, Steve Jobs was an inventor behind Apple Computers. As the now-famous story goes, Jobs and Wozniak started Apple Computers in Jobs’ family’s garage in 1976, and the work they did there made computers more accessible and more affordable for consumers. Jobs left Apple in 1985, but he returned in 1997 and revitalized the company, leading to the creation of products like the iPod and iPhone. Along with Steve Jobs, Steve Wozniak is one of the founders of Apple Computers and an inventor of the Apple I computer. Wozniak also personally invented the next model, the Apple II computer, which was a major st...
