Alan Greenspan died on 22 June 2026 from complications of Parkinson’s disease, announced by his wife Andrea Mitchell. He chaired the Federal Reserve from 1987 to 2006 across four presidents, the second-longest tenure in Fed history at 18½ years. His legacy was later clouded by the 2008 financial crisis, and in January 2026 he joined former chairs Bernanke and Yellen in publicly opposing a criminal investigation into then-chair Jerome Powell as a threat to central bank independence.
