The Man Who Knew: The Life and Times of Alan Greenspan is a biography of the former Chairman of the Federal Reserve Alan Greenspan, written by Council on Foreign Relations Senior Fellow Sebastian Mallaby.

In the book, Mallaby addresses questions about Greenspan that emerged in the wake of the 2008 financial crisis.

"Mr. Greenspan is a fascinating subject because for so long he was considered a genius, only to later be blamed for the financial crisis," wrote Andrew Ross Sorkin, reviewing the book in the New York Times.

"Mr. Mallaby does an exquisite job going beyond these two versions of the Greenspan narrative and taking the reader inside the complicated mind of a man who may have had one of the largest ever influences over our economy.
