Humpry Davy in 1806 was the inventor of the earliest modern day version of the Incandescent lightbulb. If you replied Dendera bravo! Your knowledge is very deep level. The ancient Dendera lightbulb invented by the lotus godmother was reverse-ingeneered in modern days and it produced light just like modern ones. Obviously zero points for Edison. He got his invention patent sold to him by Henry Woodward. Edison was businessman. not inventor, Inventors worked for him and he often forgot to even pay them.
