He was the No. 2 at the Federal Reserve and the I.M.F. during periods of economic turmoil, and he mentored future economic leaders, like Ben Bernanke.
Stanley Fischer, an economist and central banker whose scholarship and genial, consensus-seeking style helped guide global economic policies and defuse financial crises for decades, died on Saturday at his home in Lexington, Mass. He was 81.
The cause was complications of Alzheimer’s disease, his son Michael said.
Mr. Fischer served as the head of Israel’s central bank from 2005 to 2013, as vice chairman of the Federal Reserve Board from 2014 to 2017 and as the No. 2 officer at the International Monetary Fund from 1994 to 2001, when that agency was struggling to contain financial panics in Mexico, Russia, Asia and Latin America.
As a professor at M.I.T., he was a thesis adviser or mentor to an extraordinary range of future leaders, including Ben S. Bernanke, later chairman of the Fed; Mario Draghi, president of the European Central Bank; and Kazuo Ueda, governor of the Bank of Japan.
His former students also included two people who chaired the U.S. Council of Economic Advisers, Christina D. Romer and N. Gregory Mankiw, as well as Lawrence H. Summers, who served as secretary of the Treasury and president of Harvard University.
“He had a role in shaping a whole generation of economists and policymakers,” Mr. Bernanke said in a February 2024 interview for this obituary. That included spurring Mr. Bernanke’s initial interest in macroeconomics and monetary policy.
In 1998, The Times described Mr. Fischer as “the closest thing the world economy has to a battlefield medic.” He helped negotiate a rescue package for Russia by cellphone while standing atop a sand dune on Martha’s Vineyard, where he was on vacation.
