Most people assume that Thomas Edison invented the light bulb. This is only partially true
however. Historically speaking, many people helped developed the modern incandescent bulb.
Though Thomas Edison's achievements were by far the most significant, there are several others
that deserve some credit.
Important People In The Life Of A Light Bulb
Sir Humphrey Davy is the first person to create artificial light. While conducting experiments Davy
passed an electric arc of energy between two poles. The resulting "light" had a short life but
nonetheless contributed to the science of electricity.
In 1820 a fellow named Warren De la Rue also tried to create the incandescent light bulb. Using a
platinum coil, la Rue passed a current of electricity through a tube. This successful resulted in a
light "bulb" or sorts. However, the platinum coil used proved way too expensive to mass-produce.
Thus la Rue's creation served more as a research tool than anything else.
Still searching for the perfect bulb, Frederick de Moleyns stepped up to the plate in 1841. He used
powdered charcoal filters as a conductor for light energy. He is the first person granted a patent for
creating incandescent lamps. Then, Edward Shepard less than a decade later used a charcoal
filament to create an incandescent lamp. Like its predecessors, this light was short-lived. Around
the same time a man named Joseph Swan also started using carbon as filaments. Carbon
provided a lower cost and more efficient filament material than other metal alternatives.
In 1854 a German worker created a filament using carbonized bamboo. This successfully
produced an incandescent electric bulb. The light bulb had the same problem as its predecessors
however. Short life spans seemed to plague the early inventors of light for many years before
Edison stepped on to the scene. In 1860 Joseph Swan displayed a decent light bulb using
carbonized filaments. His problem however, was failure to create a proper vacuum and enough
electricity to product a lasting light.
Thomas Edison Enters the Light Bulb Scene
Finally Thomas Edison, after thousands of experiments, in 1879 figures out that carbonized paper
filament produces a lasting light bulb. Thomas Edison's bulb produced light for almost 15 hours.
Thus, he is credited with producing the first effective and useful incandescent bulb.
Thomas Edison tried more than 6,000 different plant species before he discovered the one that
would work as a proper filament. A few years later a gentleman named Lewis Latimer patented a
process that allowed carbon filaments to be manufactured more efficiently. His process extended

2. the life of Edison's carbon filaments, producing an even longer lasting light bulb.
Thomas Edison of course never stopped working on the light bulb. After creating the first
incandescent light bulb to last, he worked on creating the first useful incandescent lamp.
Thankfully many other researchers continued to refine Edison's work. Because of this, there are
many different varieties of bulb available today.
Let's take a peak at some of the inventions that followed the first incandescent bulb.
New Discoveries in Incandescence
The journey of the light bulb did not stop with Edison. In the early 1900s researchers discovered
that tungsten filaments were more efficient for producing long lasting light that carbon ones. Now
tungsten is the standard for light bulb filaments, even in modern times.
Today the light bulb has evolved into a work of art. There are many different categories of light
bulb today, aside from the traditional incandescent. Some of the more popular varieties include:
Full spectrum light bulbs
Automotive LED bulbs
Compact fluorescent light bulbs
Halogen light bulbs
Projector light bulbs
Tanning bed bulbs
Specialty light bulbs
As you can see, the light bulb has come a long way. Thanks to the hard efforts of many scientists,
the light bulb has evolved into a complex creation!
