Edison was not the only person responsible for the light bulb's creation. Many inventors and scientists who came before him helped pave the way for Edison's successful invention. Between 1800 and 1802 an English scientist named Humphry Davy invented the first electric light known as the electric arc. Many years later, Joseph Swan developed a light that used carbon filaments, but it was not cost effective and never went to market. Charles Francis Bush was responsible for electric lighting that was used outside to light streets and public areas. All of these innovations were an important part of the invention of the light bulb.
