He didn't invent the light bulb, or more correctly, the electric lamp, nor did he invent the screw thread.
So, screw Edison.
(Though I do think a screw thread on a lamp is far better than the spring loaded bayonet used in most domestic lighting) |

I think the bayonet came from vehicles, and other places where vibration resistance is important, so obviously for bedroom lights....

From my understanding and researches, Edison was a pretty nast unscrupulous bastard. He's credited with inventing loads of things, but in reality he invented little or nothing.
He was good at spotting ideas, which he did improve on and then patented. He had teams of people scouring round for inventions, which he then patented leaving the original inventors un rewarded.
I guess at best, he was a ruthless entrepreneur |

"The lightbulb was actually invented by Joseph Swan from Gateshead he had the first house in the world to be lit by electricity."
It depends on how far back you want to go. Alessandro Volta (who's birthday it was this week) invented the battery and passed an electric current through copper wire, which glowed. This was the first ever recording of man made production of light from electricity.
Humphry Davy used Volta's electric piles connected in series to produce high voltage sufficient to make a spark jump between two electrode, giving the electric arc lamp.
Warren de la Rue produced the first recognisable electric incandescent lamp using a platinum filament in an evacuated glass bulb.
Joseph Swan, made it cheaper by using carbonated cotton for the filament.
Everything is derivative
