According to the history, Latimer made the first carbon filament and air evacuated bulb; Edison just improved on it. So, it seems Latimer was first with the concept. Edison was a charlatan in that he stole lots of Tesla’s idea’s and while Tesla was working for him didn’t pay him his salary saying it was an American joke to hire someone and not pay them.
The article quoted above clearly says Edison invented the bulb.
No, according to the new Leftist History. And you even have that a little backassward. “Better to remain silent and be thought a fool than to speak and to remove all doubt.” Abraham Lincoln.
