This final note, a moment to remember economist Anna Schwartz, who died today at the age of 96.

Fifty years ago, she wrote a book with Milton Friedman called “A Monetary History of the United States,” that Ben Bernanke said is the best explanation there is of the causes of Great Depression.

When we had her on the program three years ago to talk about the Fed’s response to the Great Recession, Dr. Schwartz didn’t return the favor.

Anna Schwartz: Considering Bernanke’s background, you would have expected a much more, should I say a tidy kind of performance by the Federal Reserve.

‘Course, she didn’t care much for Alan Greenspan either.

Schwartz: Well, I think the verdict of history will be different with regard to his stature than it has been so far.

Anna Schwartz. She was 96. Got her Ph.D in economics, by the way, at the age of 48.
