"Anna did all of the work, and I got most of the recognition," the Nobel Prize-winning economist Milton Friedman once said.
Anna was Anna Schwartz, Friedman's co-author. She died today at age 96.
Friedman and Schwartz wrote A Monetary History of the United States, 1867 -1960. Among other things, the book argued that the Federal Reserve helped to cause the Great Depression by mismanaging the money supply.
