Long before Thomas Edison patented -- first in 1879 and then a year later in 1880 -- and began commercializing his incandescent light bulb, British inventors were demonstrating that electric light was possible with the arc lamp.

A significant invention of the late period of the Industrial Revolution was the light bulb, which was invented by Thomas Edison in 1879. Thomas Edison was an American inventor, and is famous today for many different inventions, of which the light bulb is

In 1840, British scientist Warren de la Rue developed an efficiently designed lightbulb using a coiled platinum filament in place of copper, but the high cost of platinum kept the bulb from...

Joseph Swan, alongside Thomas Edison, is the person most credited with the invention of the light bulb. The Sunderland-born chemist created the first successful incandescent filament electric lamp and gave public demonstrations of it in late 1878 and earl
