Alan Greenspan, Who Ran the Federal Reserve for 18 Years, Dies at 100

Alan Greenspan, who led the Federal Reserve — the nation's central bank — from 1987 to 2006, has died at 100. He served longer than any other Fed leader in modern times, through four presidencies and major economic crises: the 1987 stock market crash, the dot-com bust, and the housing boom that led to the 2008 financial crash. Experts disagree on his record.
