27/01/1880 Thomas Edison patented the light bulb

Contrary to the common belief, Edison did not invent the lightbulb. He had many predecessors, for example German clockmaker Heinrich Göbel or British chemist Humphry Davy. True inventor of modern lightbulb was British physicist Joseph Swan. However, Thomas Edison improved it to a great degree. His lightbulb was first commercially successful.
