Excellent points, thanks for all the input.
Yes, I am well aware that a lot of these inventions are build on other people’s ideas and the person who takes credit for it is the one who knows it the best.
Very good point with Steve Woznick and Steve Jobs. Yes, Woz was the technical genius behind the Apple but it was the Steve Jobs combination of making it useable and presenting as a great idea to the public.
Also, a lot of the subcomponents of the Apple (Floppy Drive and Hard-drive for example) were developed by others but it was Steve Jobs that put it all together in one package first.
Same point with the Macintosh, as mentioned, in that Steve Job took an idea that was already in development and assembled it together and got it out to the public.
Same point with Thomas Edison as no doubt he had a large staff supporting him, but there has to be someone putting this all together and history has given him credit even though others may have done more of the ground work.
There is also something to be said about being the first to develop a product in that it has name recognition even if the following products are better or more used.
Case in point: Xerox (the company) built the first photocopier and other companies have built better ones since then, but Xerox is still be used when referring to making a few copies.
My point on bringing this up, is that after developing a major inventions, I was wondering to see if any inventor/engineer ever had success in a subsequent invention. (Literally, lightening striking twice!! considering how rare multiple success were.)
Generally what I found is that the ones who had multiple successes were usually in the same field or related.
IE, Steve Jobs and his series of telecommunication/computing devices, although Pixar is slightly different but it still used a computers to present a graphic display.
Thanks for the comments and anymore are welcome
