Which inventor developed one of the first practical light bulbs in 1879?
Correct!
In 1879, Thomas Alva Edison and his team in Menlo Park developed a carbon filament light bulb that lasted significantly longer than many previous attempts. In October 1879, an experimental lamp with a carbonized cotton filament achieved a burning time of around 14.5 hours. However, Edison was not the only inventor who worked on electric light. Other researchers had already developed corresponding lamps; One of the important competitors was Joseph Wilson Swan in Great Britain. Edison's achievement was primarily to make the incandescent lamp practical and to further develop it as part of a complete electric lighting system. His U.S. patent application for the incandescent lamp was filed on November 4, 1879; the patent was granted on January 27, 1880.
