Alan Greenspan, the former chairman of the U.S. Federal Reserve, has died at the age of 100. Known as “The Maestro,” Greenspan led the central bank for over 18 years, serving under four U.S. presidents: Ronald Reagan, George H.W. Bush, Bill Clinton, and George W. Bush. His tenure was marked by significant economic events, including the dot-com bubble and the aftermath of the 9/11 attacks. Greenspan’s policies, often focused on deregulation and low inflation, profoundly influenced American economic policy for decades. He was a prominent figure in shaping monetary policy and navigating economic challenges during a period of substantial growth and change. His death marks the end of an era for American economics and financial leadership.
