Interview with Paul Samuelson

Find it here, run by Conor Clarke.  Excerpt:

Milton Friedman. Friedman had a solid MV = PQ
doctrine from which he deviated very little all his life. By the way,
he's about as smart a guy as you'll meet. He's as persuasive as you
hope not to meet. And to be candid, I should tell you that I stayed on
good terms with Milton for more than 60 years. But I didn't do it by
telling him exactly everything I thought about him. He was a
libertarian to the point of nuttiness. People thought he was joking,
but he was against licensing surgeons and so forth. And when I went
quarterly to the Federal Reserve meetings, and he was there, we agreed
only twice in the course of the business cycle.
