Who is credited with the invention of the light bulb?

Thomas Edison is credited with the invention of the practical light bulb, which revolutionized the way people illuminated their homes and businesses. Edison's version of the light bulb, developed in the late 19th century, utilized a carbon filament that could last for many hours when electrified, making it a viable alternative to gas lights. His work not only improved the design of the light bulb but also contributed to the development of the electrical power system necessary to supply electricity to households.

While other inventors, such as Sir Humphry Davy and Joseph Swan, made early advancements in electric lighting, it was Edison's successful commercialization of the light bulb and the establishment of electrical infrastructure that truly made electric light a practical reality for everyday use. This is why he is often prominently recognized in the context of the light bulb's invention.
