Thomas Edison Did Not Invent The Bulb
Humphry Davy is the man who came up with the first electric light in 1802. And in 1860, inventor Joseph Wilson Swan concocted the first working prototype of a light bulb. He used carbonized paper filaments, but his invention wasn’t without a few problems.
That’s where Edison entered the picture. He eliminated a few technical issues and came up with a more practical, cheaper, and safer prototype according to Live Science.
