Genius: The Life and Science of Richard Feynman
A solid biography, though I don’t have anything in particular to say about it. It throws in all the classic anecdotes and quotes you expect (which are more than worth their weight in gold—certainly, the price of admission) doesn’t try to whitewash Feynman despite the temptation to hero-worship, and includes some critical examination, does at least try to explain all the physics which earned Feynman his prestige, etc.
It’s a well-regarded widely-read biography on an excellent subject which I have nothing to say against (aside from Gleick unfortunately repeating Feynman’s story about his IQ without explaining the many reasons why this doesn’t mean what people are forever taking it to mean).
