The first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.
In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.
Lewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.
In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed.
In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.
Edison was actually the inventor of the electric lighting system, complete with generators, distribution power lines, usage meters, and light bulbs. No previous light bulb inventor had put all those parts together needed to make a practicalbusiness using them.
Nikola Tesla and the innovator Thomas Edison worked together. Edison was credited with the invention, but it was actually partner Tesla who invented the first successful light bulb, and Edison developed it into the present one.
There is enough proof to say that the Egyptians came up with and used the light bulb.
People say that Edison invented the lightbulb...but they are wrong. It is Scottish inventor James Bowman Lindsay who made it in 1835 but didn't patent it.
You might think it was Thomas Edison, but it wasn't!
The first light bulb was made by an English scientist called Humphry Davy.
Then, the Serbian-American inventor Nikola Tesla perfected the light bulb.
