Invention of the light bulb

The invention of the light bulb is primarily attributed to Thomas Edison, who developed the first practical and long-lasting incandescent bulb in 1879. However, the concept of electric light had been explored earlier by inventors like Humphry Davy and Joseph Swan. Edison's improvements included a high-resistance carbon filament and a vacuum bulb, which significantly increased the bulb's lifespan and efficiency. This innovation revolutionized indoor lighting and paved the way for widespread use of electric light.
