I read both several years ago, and they are spectacularly fine reads. True life stories about a simply brilliant, eclectic, eccentric, down to earth guy who lived in very interesting times, always viewing those times with a very, very insightful eye.
There is also a PBS documentary out there somewhere about Feynman that is well worth a viewing. So revered is this guy, that a friend of mine even wrote a song about him some years back, which I engineered for her (and played dhoumbek!) and which she subsequently used to be chosen to participate in a songwriters' showcase here in KC.
Feynman was a very interesting man.
