This man doesn't get enough credit and Steve Jobs gets way too much.

So much of what the Mac was came from what Tesler built into the Lisa project based on his personal convictions on what computing could be.

Jobs got a reputation for "taste" but a lot of the origins of what that looked like in practice were Tesler (and others, obviously) driven.

Jobs can be credited more for bringing all these people - talented & tasteful as they were - together through his mix of passion, charisma and "reality distortion field", IMHO, than making all the tasteful decisions himself.

He was aware of that: in one video, he pointed out that once he managed to hire the top 1-2 people, the other people will come because they'd want to work with the best.

I agree with this, but it's also true that Tesler was a difficult, argumentative blocker and dinosaur at Yahoo! in the mid-2000s. The upper management there blew such massive opportunities, over and over and over again.
