Alan Greenspan, longtime chairman of the Federal Reserve, dies at 100

Alan Greenspan, the longtime chairman of the Federal Reserve, has died, his wife confirmed. He was 100 years old.

"Alan passed away at our home this morning at the age of 100 from complications of Parkinson's Disease," Andrea Mitchell, his wife and a chief correspondent at NBC News, said in a statement published by NBC News on Monday.

The economist is remembered for leading the American central bank amid periods of historic U.S. economic expansion, while critics have also said his policies contributed to and exacerbated the mortgage crisis and financial crash of 2008.

Greenspan, a libertarian Republican, became the 13th chairman of the Board of Governors of the Federal Reserve System two months before the stock market crash on Oct. 19,1987, known as Black Monday. He was credited with moving quickly to alleviate investors' fears after the crash and was instrumental in ensuring the Federal Reserve made plenty of money available to alleviate the impact on financial markets. Stocks quickly rebounded.

He was appointed Fed chair by four different presidents during his career, first by Ronald Reagan in 1987. Greenspan continued to serve as Fed chairman under presidents George H. W. Bush, Bill Clinton and George W. Bush. He steered the U.S. economy through the economic boom in the 1990s, the dotcom bubble, and the Sept. 11, 2001, terrorist attacks. His final term as chair ended on Jan. 31, 2006.
