JOSEPH SWAN IS THE REAL (FIRST) INVENTOR OF LIGHT BULB

Whoever, thought Thomas Edison is the inventor. Think again, think again and again. Your mind won't answer. So, let's go to wikipedia.

Sir Joseph Wilson Swan KBE (31 October 1828 – 27 May 1914) was a British physicist and chemist, most famous for the invention of the incandescent light bulb for which he received the first patent in 1878. His house (near Newcastle Upon Tyne, England) was the first in the world to be lit by a lightbulb.

Ediswan

In 1883 the Edison & Swan United Electric Light Company was established. Known commonly as "Ediswan" the company sold lamps made with a cellulose filament that Swan had invented in 1881. Variations of the cellulose filament became an industry standard, except with the Edison Company. Edison continued using bamboo filaments until the 1892 merger that created Edison General Electric, and that company then shifted to cellulose.
