Henry Ford seems an apt comparison. "Industrialist and business magnate", from Wikipedia's Henry Ford article, seems to pretty much cover it. Though with less of a focus on making products affordable for the normal person (which isn't necessarily a bad thing, just a difference in priorities).

That still makes him a pretty big deal, of course.

Yeah, Musk, Ford, Jobs, and Edison are all a big deal regardless of their role in actually inventing technology. I think Jobs is the most appropriate analog because he also has a public perception as being the person who created the tech which isn't really accurate. I'm not sure Ford had that reputation and Edison was more hands on.

It is also probably worth nothing that they all had another trait in common. They were all notorious assholes for various reasons.

Yeah, sorry, should have included that in my other post, but I do agree that Jobs is a decent analog, too. Similar public profile, sort-of similar reputation, though Jobs wasn't as prone to strident, public bullshitting.
