Who invented the electric light bulb in 1879

In the first public demonstration of his incandescent lightbulb, American inventor Although the first incandescent lamp had been produced 40 years earlier, no inventor had been able to come up with a practical design until Edison embraced the challenge in the late 1870s. After countless tests, he developed a high-resistance carbon-thread filament that burned steadily for hours and an electric generator sophisticated enough to power a large lighting system. Born in Milan, Edison’s experiments were guided by his remarkable intuition, but he also took care to employ assistants who provided the mathematical and technical expertise he lacked. At Menlo Park, Edison continued his work on the telegraph, and in 1877 he stumbled on one of his great inventions–the phonograph–while working on a way to record telephone communication. Public demonstrations of the phonograph made the Yankee inventor world famous, and he was dubbed the “Wizard of Menlo Park.” Although the discovery of a way to record and play back sound ensured him a place in the annals of history, the phonograph was only the first of several Edison creations that would transform late 19th-century life. Among other notable inventions, Edison and his assistants developed the first practical incandescent lightbulb in 1879 and a forerunner of the movie camera and projector in the late 1880s. In 1887, he opened the world’s first industrial research laboratory at West Orange, New Jersey where he employed dozens of workers to i...

Although he may be called the first commercially viable incandescent light inventor, he was not the first or only individual attempting to create the incandescent light bulb. There were many other individuals, including Joseph Swan (UK) and Heinrich G. Darcys (Austria), who made electric lights before Edison, but their various experiments largely failed to produce a successful product that could be mass-marketed. These inventors worked in the same way as Edison, they each had their own theoretical approach to designing an electric light, but Edison’s approach had one key advantage. However, Edison is generally credited with the invention because his version was able to outpace the predecessors due to a mix of three elements: • An efficient incandescent substance • A higher vacuum than previous versions were capable of • A high resistance that made power distribution from a central location lucrative. Edison’s key advantage came from his choice of a carbonized bamboo filament, which he was able to fashion in such a way that it lasted relatively long and burned brightly. In addition, Edison worked with a greater vacuum than others had been able to achieve, causing the light to burn clearly rather than suffocating itself by smoking up its own container. 3.6 WhiteLEDs: Early Light Bulbs The invention of the light bulb was a series of incremental steps, each improving slightly on earlier designs. It started with Humphry Davy in 1802 when he used a platinum strip to remove resid...
