[1] [2] These carbon filament bulbs, the first electric light bulbs, became available commercially that same year. [3] In 1904 a tungsten filament was invented by Austro-Hungarians Alexander Just and Franjo Hanaman , [ 4 ] and was more efficient and longer-lasting than the carbonized bamboo filament used previously.

English engineer Joseph Swan invented the Incandescent light bulb. 1879: American physicist Edwin Herbert Hall discovered the Hall Effect. 1879: Thomas Alva Edison introduced a long-lasting filament for the incandescent lamp. 1880: French physicists Pierre Curie and Jacques Curie discovered Piezoelectricity. 1882
1879: Joseph Swan and Thomas Edison both patent a functional incandescent light bulb. Some two dozen inventors had experimented with electric incandescent lighting over the first three-quarters of the 19th century but never came up with a practical design. [ 433 ]
It was more than 140 years ago — 1879 — that Thomas Edison dramatically advanced the economy, efficiency, safety and the well being of humans by inventing the incandescent light bulb. No ...
Sir Joseph Wilson Swan FRS (31 October 1828 – 27 May 1914) was an English physicist, chemist, and inventor.He is known as an independent early developer of a successful incandescent light bulb, and is the person responsible for developing and supplying the first incandescent lights used to illuminate homes and public buildings, including the Savoy Theatre, London, in 1881.
1878 – Thomas Edison, following work on a "multiplex telegraph" system and the phonograph, invents an improved incandescent light bulb. This was not the first electric light bulb but the first commercially practical incandescent light. In 1879 he produces a high-resistance lamp in a very high vacuum; the lamp lasts hundreds of hours. While ...
Weeks joined Corning 132 years into the company’s 173-year history. Founded in 1851 by a merchant named Amory Houghton Sr., it began as the Bay State Glass Co., a small company in Massachusetts.
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. [73] 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 ...
