In what year did Thomas Edison build his famous lamp?

Thomas Edison built his famous incandescent light bulb in 1879, which marked a significant milestone in electrical engineering and innovation. This development occurred after years of experimentation with different materials and designs aimed at creating a practical electric light. Edison's successful creation of a light bulb that lasted for hours made it commercially viable, leading to the widespread adoption of electric lighting and transforming how people lived and worked.

The years surrounding this achievement showcase Edison's determination and incremental innovations in the field, but it was in 1879 that he truly made the breakthrough that would lay the foundation for modern electric lighting. This is why 1879 is considered the correct year associated with Edison's invention of the lamp.
