Having just finally read (well, listened to) Kuhn's book, I can say:
(a) I wouldn't quite characterize the book as being "about this theory" — it's a bit more nuanced. He definitely says that it's usually younger scientists with less invested in the currently reigning theory that are most likely to push forward a revolution. However, I don't recall any examples in the book of people who where wholly _unaware_ of the previous theory.
(b) You should absolutely, definitely read it. It's a classic for a reason, and the writing style is a delight.
