Alan Greenspan, Fed Chair for 19 Years, Dies at 100

Alan Greenspan, who led the Federal Reserve for nearly two decades under four presidents, died Sunday at age 100. He served as Fed chair from 1987 to 2006, steering the economy through the 1987 stock crash, the dot-com bust, and the aftermath of September 11.

Greenspan's reputation as a near-infallible "maestro" of monetary policy dimmed considerably after the 2008 financial crisis, when his long-held faith in financial markets' capacity for self-regulation came under sharp scrutiny. He later acknowledged his model of how markets work had a flaw. His tenure is a touchstone in current debates over Fed independence -- and the approach of current chair Kevin Warsh.
