Question: who made the first light bulb and how did he/she make it

The common answer is Thomas A. Edison, but not really.

It seems that Ebenezer Kinnersley was the first one to show a working concept, that is a wire so hot that glows light, but he was far from having something like the commercial light bulb that Edison invented.

This story made us notice that in science there are a lot of different jobs. People working on the basic principles and also people working on creating technologies from this basic principles. People in the lab and people working with equations in his minds.
