Was the light bulb Thomas Edison's first invention?

The first practical incandescent light bulb. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.J., tested more than 3,000 designs for bulbs between 1878 and 1880. In November 1879, Edison filed a patent for an electric lamp with a carbon filament.

What is a fact that not that many people know about Thomas Edison?

I have two off the top of my head:He was partially deaf his entire life. And his only invention that worked perfectly the very first time was the phonograph. Ironically, it was his only invention that he didn't think would work at all!


When did Isaac Newton invent the light bulb?

I'm sorry to say that he didn't In 1878 Joseph Wilson Swan, an English physicist and Chemist received a patent for his invention and his house was the first in the world to be lit by electric light. See Swan's Wikipedia entry Thomas Edison,upon seeing the British patent,or open letter, made copies and publicised his work. Swan was keen to make money from his invention and decided set up a joint venture which became the 'Ediswan' company in 1883. I am sure the name Swan would not have figured in the name unless Edison was forced to retract his claim of prior invention. Edison did produce an efficient steam driven DC dynamo known as' Long Waisted Annies' to drive his lamps and famously lit the road out side his workshop. This the likely source of your error.
