Thomas Alva EDISON
1879 - Incandescent light bulb is invented (Thomas Alva Edison, United States)

In the year 1879, a pivotal moment in technological advancement unfolded when Thomas Alva Edison, an industrious inventor from the United States, successfully developed the incandescent light bulb. This groundbreaking invention marked a significant leap forward in the realm of artificial illumination. Edison's design employed a carbon filament, which, when electrified, emitted a steady and reliable light, outlasting previous attempts at electric lighting. This innovation not only extended the hours of productive activity beyond sunset but also paved the way for the widespread adoption of electric power, fundamentally transforming daily life and industry. Edison's incandescent light bulb stands as a testament to human ingenuity and the relentless pursuit of progress during the late 19th century.

Edison still claims that his electric light is a complete success, and says he can now furnish it at one-third the cost of gas, but he thinks that he can make the difference in price much greater, and hence the delay. In San Francisco, a company has been formed and is now ready to furnish light in any part of the city, while the directors claim they can light all the streets of the city at a saving of from $150,000 to $200,000 a year to taxpayers. The public has heard enough about what Edison and others promise to do in the way of cheap light, and is now anxiously waiting for the performance.
