b. 1954

Two Nobel uncles, a Treasury seal, and a verdict still open

Dinner-table economics was the family business. Robert and Anita Summers both taught at the University of Pennsylvania, and their son grew up as the nephew of two future Nobel laureates: Paul Samuelson, his father's brother, and Kenneth Arrow, his mother's. Robert had changed the family name from Samuelson. Larry entered MIT at 16, meant to read mathematics, switched to economics, and qualified three times for the National Debate Tournament. A Harvard doctorate followed in 1982. The next year, at 28, he became one of the youngest tenured professors in the university's modern history. In 1993 the American Economic Association awarded him the John Bates Clark Medal, which goes to an American economist under 40.

He left Harvard in 1991 for the World Bank, where he served as chief economist. Treasury followed in 1993 — under secretary, then deputy to Robert Rubin, then Secretary from July 1999. The Mexican peso rescue, the 1997 Asian financial crisis and the Russian default all landed on his desk, and in Korea he pressed for higher interest rates and a tighter budget in mid-recession. In 2001 he returned to Harvard as its 27th president. Eight years later Barack Obama put him in charge of the National Economic Council as the financial crisis deepened.

In January 2005, at a National Bureau of Economic Research conference, he named as one hypothesis for the shortage of women in top science and engineering faculty jobs a "different availability of aptitude at the high end" — greater male variability in test scores. He apologized repeatedly. On March 15, 2005, Harvard's arts and sciences faculty passed a lack-of-confidence motion 218 to 185, and he resigned in 2006. In December 1991 he signed a World Bank memo calling the logic of dumping toxic waste in low-wage countries "impeccable". He and Lant Pritchett, the staffer who claims authorship, call it sarcasm. He also opposed Brooksley Born's push to regulate over-the-counter derivatives and backed the Commodity Futures Modernization Act. Critics tie the 2008 crash partly to that. In 2009 he quoted Keynes on changing one's opinion when circumstances change.

The verdict on him is not settled, and 2025 unsettled it further. On November 12, 2025, Congress released emails documenting correspondence with Jeffrey Epstein between 2017 and 2019, long after Epstein's 2008 sex-offense conviction. Summers called the association "a major error of judgement". Within a week he stepped back from his public commitments, among them the Hamilton Project, the Center for American Progress and the chairmanship of the Center for Global Development, ended a paid Bloomberg role and resigned from the board of OpenAI. Harvard opened an investigation and he went on leave. The American Economic Association barred him for life on December 2, 2025. In February 2026 he announced he would leave his Harvard professorship.
