Influential economist Alan Greenspan died Monday morning at the age of 100.
NBC News journalist Andrea Mitchell announced to CNBC that her husband of nearly three decades died from complications of Parkinson’s Disease.
Greenspan headed the Federal Reserve for nearly two decades, and served the second longest tenure — just four months short of William McChesney Martin.
He was appointed chairman in 1987 by President Ronald Reagan and held the position until his retirement in 2006, serving under four presidents; Ronald Reagan, George H.W. Bush, Bill Clinton and George W. Bush.

Greenspan guided the U.S. economy through a series of turbulent and defining moments, including the 1987 stock market crash, the Asian financial crisis, the dot-com boom and bust, and the aftermath of the Sept. 11 terrorist attacks.
He quickly became known for his cryptic public remarks, and became a Wall Street celebrity during the economic expansion of the 1990s, earning the nickname “the Maestro.”

His infamous 1996 warning about “irrational exuberance” remains one of the most famous phrases in modern economic history.
Greenspan’s legacy was the subject of debate by some economists who argued that some of his policies may have laid the groundwork for the 2008 financial crisis.
