Who was the first person to invent the light bulb?

Answer 1

The first incandescent 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. This is called an electric arc.

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.

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 light 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.

Answer 2

Thomas Edison invented the 1st successful lightbulb is the common misconception. The truth is that he did not.

He is credited for having the first incandescent light, but that is certainly not the first light bulb.

Inventor Heinrich Göbel, later Henry Goebel (April 20, 1818 - December 4, 1893), was a precision mechanic born in Springe, Germany. In 1848, he emigrated to New York City and lived there until his death in December 4, 1893.

In 1893, the American public and in Europe took notice of him by reporting that he had developed incandescent light bulbs comparable to those invented by Thomas Alva Edison 25 years earlier (1879). Goebel did not apply for a patent.

In 1893 the Edison Electric Light Co. brought suit for infringing Edison´s patent against three manufacturers of incandescent lamps. The defense of these companies claimed the Edison patent was void because of the same invention of Henry Goebel 25 years earlier, known as the Goebel-Defense.

Answer 3

The light bulb was the first consumer product to create a widespread demand for electricity. The demand for electricity created the impetus for investment in electrical distribution grids. The electrical grids then led to further productivity, innovation, and automation on a large scale.

Answer 4

Thomas Edison perfected the electric light bulb.
