Larry Summers
American economist, 71st Treasury Secretary, 27th Harvard president, and NEC director.
Lawrence Henry Summers (born November 30, 1954) is an American economist who held several high-profile roles: the 71st U.S. Secretary of the Treasury (1999–2001), the 27th president of Harvard University (2001–2006), and the eighth director of the National Economic Council (2009–2010). He was a Charles W. Eliot University Professor at Harvard Kennedy School until resigning in February 2026.
Summers became a Harvard economics professor in 1983, then left in 1991 to serve as the World Bank’s chief economist until 1993. That year, he was appointed Under Secretary for International Affairs at the Treasury under President Bill Clinton, and in 1995 he became Deputy Secretary under his mentor Robert Rubin. He succeeded Rubin as Treasury Secretary in 1999. During the Clinton administration, Summers helped shape U.S. responses to the 1994 Mexican economic crisis, the 1997 Asian financial crisis, and the 1998 Russian financial crisis. He also played a key role in the Harvard Institute for International Development, in American-advised privatization of post-Soviet economies, and in U.S. financial deregulation, including the repeal of the Glass–Steagall Act.
After Clinton’s term, Summers served as Harvard’s president from 2001 to 2006. He resigned after a no-confidence vote by faculty, driven largely by conflicts with Cornel West, financial conflict-of-interest questions regarding his ties to Andrei Shleifer, and a 2005 speech where he suggested three reasons for the underrepresentation of women in science and engineering: possible “different availability of aptitude at the high end,” along with discrimination and socialization.
Following his first Harvard departure, Summers worked as a managing director at the hedge fund D. E. Shaw & Co. He returned to public service under President Barack Obama, directing the National Economic Council from January 2009 to November 2010, where he was a key figure in the response to the Great Recession.
In November 2025, Summers went on leave from his Harvard teaching and his role as director of the Mossavar-Rahmani Center for Business and Government due to an investigation into his ties to Jeffrey Epstein.
**Early life and education** Summers was born in New Haven, Connecticut, on November 30, 1954, into a Jewish family. His parents, Robert Summers (who changed the surname from Samuelson) and Anita Summers (of Romanian-Jewish ancestry), were both economics professors at the University of Pennsylvania. He is the nephew of Nobel laureates Paul Samuelson and Kenneth Arrow. He grew up mostly in Penn Valley, Pennsylvania, and attended Harriton High School. At 16, he entered MIT, initially planning to study mathematics but switching to economics, graduating in 1975. He was active on the MIT debate team, qualifying for the National Debate Tournament three times. He earned his Ph.D. from Harvard in 1982.
**Early career (1983–2001)** In 1983, at 28, Summers became one of Harvard’s youngest tenured professors. He was a visiting academic at the London School of Economics in 1987. His research spans public finance, labor economics, financial economics, macroeconomics, international economics, economic demography, economic history, and development economics. He won the John Bates Clark Medal in 1993 and, in 1987, became the first social scientist to receive the Alan T. Waterman Award. He is a member of the National Academy of Sciences. His popular courses at Harvard included American Economic Policy and The Political Economy of Globalization. He worked on the Council of Economic Advisers under President Reagan (1982–1983) and advised the Dukakis presidential campaign in 1988.
**World Bank (1991–1993)** Summers left Harvard in 1991 to serve as Vice President of Development Economics and Chief Economist at the World Bank until 1993. There, he helped design strategies for developing countries, worked on the loan committee, guided research and statistics, and oversaw external training. His research included an influential report showing high returns from investing in girls’ education in developing nations. *The Economist* described him as a “famous contrarian” often at the center of heated policy debates.
**“Dirty industries” controversy** In December 1991, while at the World Bank, Summers signed a memo that was leaked to the press. Lant Pritchett later claimed authorship, and both men said it was intended as sarcasm. The memo stated that “the e...

Lore & Background
Summers became a professor of economics at Harvard University in 1983. He left Harvard in 1991, working as the chief economist of the World Bank from 1991 to 1993. In 1993, Summers was appointed Under Secretary for International Affairs of the United States Department of the Treasury under President Bill Clinton's administration. In 1995, he was promoted to Deputy Secretary of the Treasury under his long-time political mentor Robert Rubin. In 1999, he succeeded Rubin as Secretary of the Treasury. While working for the Clinton administration, Summers played a leading role in the American response to the 1994 economic crisis in Mexico, the 1997 Asian financial crisis, and the 1998 Russian financial crisis. He was also influential in the Harvard Institute for International Development and American-advised privatization of the economies of the post-Soviet states, and in the deregulation of the U.S. financial system, including the repeal of the Glass–Steagall Act. Following the end of Clinton's term, Summers served as the 27th president of Harvard University from 2001 to 2006. Summers resigned as Harvard's president in the wake of a no-confidence vote by Harvard faculty, which resulted in large part from Summers's conflict with Cornel West, financial conflict of interest questions regarding his relationship with Andrei Shleifer, and a 2005 speech in which he offered three reasons for the under-representation of women in science and engineering, including the possibility that there exists a 'different availability of aptitude at the high end', in addition to patterns of discrimination and socialization. After his first departure from Harvard, Summers worked as a managing director at the hedge fund D. E. Shaw & Co. Summers rejoined public service during the Obama administration, serving as the director of the White House United States National Economic Council for President Barack Obama from January 2009 until November 2010, where he emerged as a key economic decision-maker in the Obama administration's response to the Great Recession. He went on leave from his teaching responsibilities at Harvard and his role as the director of the Mossavar-Rahmani Center for Business and Government in November 2025 due to an investigation into his ties to Jeffrey Epstein.
Reader's Guide
Summers was born in New Haven, Connecticut, on November 30, 1954, into a Jewish family. He was the son of two economists, Robert Summers and Anita Summers, who were both professors at the University of Pennsylvania. He is also the nephew of two Nobel laureates in economics: Paul Samuelson and Kenneth Arrow. He spent most of his childhood in Penn Valley, Pennsylvania, where he attended Harriton High School. At age 16, he entered MIT, graduating in 1975. He attended Harvard University as a graduate student, receiving his Ph.D. in 1982. In 1983, at age 28, Summers became one of the youngest tenured professors in Harvard's history. He was a visiting academic at the London School of Economics in 1987. He received the John Bates Clark Medal in 1993 and the Alan T. Waterman Award in 1987. Summers was on the staff of the Council of Economic Advisers under President Reagan in 1982–1983. He also served as an economics adviser to the Dukakis Presidential campaign in 1988. Summers left Harvard in 1991 and served as the Vice President of Development Economics and Chief Economist for the World Bank until 1993. In December 1991, while at the World Bank, Summers signed a memo that was leaked to the press. Lant Pritchett has claimed authorship of the private memo, which both he and Summers say was intended as sarcasm. The memo stated that 'the economic logic behind dumping a load of toxic waste in the lowest wage country is impeccable and we should face up to that. [...] I've always thought that under-populated countries in Africa are vastly underpolluted.' According to Pritchett, the memo, as leaked, was doctored to remove context and intended irony. In 1993, Summers was appointed Undersecretary for International Affairs and later in the United States Department of the Treasury under the Clinton Administration. In 1995, he was promoted to Deputy Secretary of the Treasury under Robert Rubin. Much of Summers's tenure at the Treasury Department was focused on international economic issues. He was deeply involved in the Clinton administration's effort to bail out Mexico and Russia when those nations had currency crises. Summers set up a project through which the Harvard Institute for International Development provided advice to the Russian government between 1992 and 1997. Summers encouraged then-Russian leader Boris Yeltsin to use the same 'three-ations' of policy he advocated
