The invention of the light bulb is attributed to Thomas Alva Edison. Edison, an American inventor and businessman, is widely recognized for his work on developing practical electric lighting. In 1879, he successfully created a long-lasting and commercially viable incandescent light bulb, which played a significant role in revolutionizing the way we illuminate our homes and cities. Although Edison is often associated with the invention of the light bulb, it is important to note that there were several inventors and scientists who made contributions to the development of electric lighting before him, including Humphry Davy, Warren de la Rue, and Joseph Swan.
