Hello dbhalling,
Thank you for this presentation. It was quite informative. I am pleased to find I am not the only one that can't immediately recall every name. Isn't it strange and frustrating when you cannot recall a name like Joseph Swan on demand, but later it comes out of your mouth naturally with out trying? :) The story of Edison and Swan is quite interesting. http://www.cio.com/article/2441341/consu... I think Edison deserves the credit though, because while he didn't "invent" the first light-bulb, what he did invent was the first practical light-bulb. This was the real benefit and creation of value.
It was quite apparent and put a fine point on the matter when at the end you had to turn on the lights!
Regards,
O.A.
