Alan Greenspan, the former chairman of the Federal Reserve whose 19-year tenure defined modern American monetary policy, has died at the age of 100.

His passing was confirmed on Monday by his wife, journalist Andrea Mitchell, who notified NBC News of the death.

Greenspan died at his home in New York.

Greenspan served as Fed chairman from 1987 to 2006, overseeing a period of significant economic expansion and financial innovation.

Known as the "Maestro" for his ability to navigate the economy through various crises, including the 1987 stock market crash and the dot-com bubble, he became one of the most influential figures in global finance.

His approach to monetary policy, characterized by a belief in market efficiency and a reluctance to intervene preemptively, shaped the regulatory landscape for decades.
