Have you heard of the American scientist, inventor and businessman Thomas Edison? He lived from 1847 to1931.
The Science Museum has some great Thomas Edison stuff.
During the museum's Wallace & Gromit: A World of Cracking Ideas exhibition (now closed), the Science Museum made a film about the telephone Thomas Edison designed.

On 27 January, 1880 Edison was granted a patent for his electric light bulb.
The light bulb, or Edison filament lamp as it was known, has one loop of carbon filament which glows when a current of electricity passes through it.
This lamp in the Science Museum collection was made one year after Joseph Swan's original 1878-1879 electric light bulb.
However, both lamps were already out of date by 1883 when Swan and Edison started their successful Edison and Swan United Electric Light Company in Britain.
