Paul,
I have just read the part about the Ediswan
Company.
The first sentence is not entirely correct,
(as far as I was taught).
I was under the impression that Charles Swan was the first person to invent a working light bulb, however, two years later, Thomas Edison (Patented), the first? light bulb.
Sorry to pin-prick, but this is why people believe, that Edison invented the light bulb,
when Swan actually did. [Linked Image]
