I think my relatives are familiar with the name Edison. After all, he has been active in our primary school students’ textbooks and studying his famous quotes.

Most importantly, historical stories tell us that Edison invented the light bulb.

But in fact, was Edison really inventing the light bulb?

According to historical stories, on October 21, 1879, after thousands of experiments in his laboratory, Edison used carbonized wrapped cotton thread as a filament to make the world's first light bulb.

This light bulb emits the light of about 10 kerosene lamps, allowing people to truly see the world in the dark.

So the name Edison is associated with the light bulb.

But is this story true? Unfortunately, this story is just a story and not true.

In fact, as early as 1801, a British chemist named David completed the electrification of platinum wire. Nine years later, he invented the electric candle, using the arc between two carbon rods to Complete lighting.

Of course, according to the lighting logic of "light bulb", this is not a real light bulb.

So we stretched the timeline to 1854. The American scientist Goebbels used carbonized bamboo silk and placed it in a vacuum glass bottle to energize it and emit light. At that time, the light bulb in Goebbels's experiment could glow continuously for 400 hours.

This was the first real light bulb in history, but Goebbels did not apply for a patent at the time.

In 1874, two Canadian electricians invented a technology. They filled the glass bubble with nitrogen to make the charged carbon rod glow, which was equivalent to taking Goebbels' technology one step further.

As expected, these two people would be the first inventors of the light bulb. Unfortunately, they lacked follow-up funds at that time, that is, they had no money. Doing scientific research itself is a super expensive thing, so they sold this technology to Edison as we know it in 1875.

After Edison obtained this technology, he began to study light bulbs. Unfortunately, Edison was too slow.

Although he obtained the molding technology, in 1878, an Englishman named Wilson also completed a "light bulb powered by carbon filaments in a vacuum" and immediately applied for a patent.

The next year, after thousands of studies, Edison finally discovered the material of carbonized cotton silk. He was very excited, thinking that he had led mankind a big step towards a new world.

But what he didn’t know was that as early as 1860, Wilson had discovered that carbonized cotton filament could be used as a lamp filament.

In 1880, Edison again discovered that carbonized bamboo silk was better than carbonized cotton silk, but Wilson actually discovered this in 1854.

It can be seen that Wilson was actually twenty or thirty years earlier than Edison, which Edison did not know.
