The creation of the light bulb is thought to have begun in 1800 with Italian inventor Alessandro Volta s invention of the voltaic wire, which provided the first electrical current. That same year, English scientist Humphrey Davy created the first electric light. Throughout the next several decades, it is estimated that as many as 20 inventors worked on inventing a long-lasting incandescent light bulb. In 1879, Edison became the first to succeed. His bulb could burn for about 1,500 hours, compared with previous versions that lasted only minutes."

No. I wasn't asking the silly questio9ns in the first place, let alone pontificating about stuff that I clearly didn't know much about.

Except that Humphrey Davey was invoked in a way that didn't have much to do with the historical record. "Hypotheticals" that are compleltley off the wall don't clarify anybody's thinking.

The reference to Humphrey Davy wasn't Rickman's and your dragging Davy in didn't clarify anybody's thinking.

Why should I? The historians did it many years ago, not to mention Swan and Edison's patent lawyers, and Edison lost, in court, and in the historical record. His publicity machine ignored this at the time, and Swan was happy to leave him to exploit the US market for their mutual benefit.

Wow. Most people would settle for asserting that a 78 year gap was persuasive argument, but you have to tell us that you find it personally satisfying.

So your "hypotheticals" are now promoted to "distinguishing inventive elements". You do like your straw men, but promoting them in mid-argument is a little transparent, even for you.
