Thomas Edison Lightbulb. Let there be Light! Historians agree that Thomas Edison was not the inventor of the electric light bulb, but he did produce the first commercially viable one.
In 1840, British scientist Warren de la Rue also demonstrated a light bulb. In 1841, British inventor Frederick DeMoleyns patented a light bulb and in 1844 American John Wellington Starr filed a U. S. patent caveat for an incandescent lamp.
