Biography

Sarah Igo's primary research interests are in modern American cultural, intellectual, legal and political history, the history of the human sciences, the sociology of knowledge, and the history of the public sphere.

Her most recent book, The Known Citizen: A History of Privacy in Modern America (Harvard University Press, 2018), traces U.S. debates over privacy beginning with “instantaneous photography” in the late nineteenth century and culminating in our present dilemmas over social media and big data. Winner of the Jacques Barzun Prize in Cultural History and the Merle Curti Award for Intellectual History, The Known Citizen was also named one of the Washington Post's “notable non-fiction books” of 2018.

Igo's first book, The Averaged American: Surveys, Citizens, and the Making of a Mass Public (Harvard University Press, 2007), explores the relationship between survey data—opinion polls, sex surveys, consumer research—and modern understandings of self and nation. An Editor’s Choice selection of the New York Times and one of Slate’s Best Books of 2007, The Averaged American was the winner of the President's Book Award of the Social Science History Association and the Cheiron Book Prize as well as a finalist for the C. Wright Mills Award of the American Sociological Association. Igo is also a co-author of Bedford/St. Martin’s American history textbook, The American Promise.

11 Historians Predict How Joe Biden Will Be Remembered

Politico  online

2025-01-17

The evaluation of a U.S. presidency traditionally hinges on promises and reversals, accomplishments and failures, in domestic and foreign policy. In Joseph R. Biden Jr.’s case, it would encompass, on the home front, his concerted work to stem the Covid-19 pandemic and his ambitious, New Deal-inflected infrastructure and economic policies — but also the politically debilitating inflation that helped doom his party’s chances in the 2024 election. On the world stage, it would weigh Biden’s successful rallying of Western nations in support of Ukraine and apparent clinching of a cease-fire agreement between Israel and Hamas in his twilight hours as commander-in-chief against the disastrous pullout of U.S. troops from Afghanistan and failure to prevent the massive death toll in Gaza.

Are We on the Cusp of a New Political Order?

The New York Times  online

2024-11-01

And finally, Sarah Igo, “The Known Citizen” — very different kind of book — “A History of Privacy in Modern America.” We’re talking about morality, we’re talking about community, and of course, social media has put the question of privacy and what constitutes privacy and what’s private and what’s public — such an urgent question in understanding America. And she gives us a wonderful hundred-year overview of how Americans in almost every generation have redefined the boundary between private and public, and I found that extremely useful in thinking about where America is at in the 21st century.

College Uncovered: What Do You Learn and What Will You Earn?

The Hechinger Report  online

2024-05-30

As an intellectual historian, Igo says, historically, what students learn can’t be captured in a single answer or data point.

"Because universities and colleges offer such an incredible wealth of options — electives, majors, minors, small credential programs. It’s the wealth of what is offered. And then the number of pathways through is really quite astonishing and would have astonished someone looking at college, or who went to college 100 years ago, or honestly even 75 years ago. The big explosion in electives and kind of choose your own adventure really happened after the mid century, mid 20th century."

The beginnings of the end of privacy

The Hedgehog Review

Sarah E. Igo

2015

What has happened to our privacy? Certainly, if recent popular titles are to be trusted--The End of Privacy, The Unwanted Gaze, The Naked Crowd, No Place to Hide (two different books!), Privacy in Peril, The Road to Big Brother, One Nation under Surveillance, and perhaps the creepiest entrant, I Know Who You Are and I Saw What You Did--we Americans are in the midst of an unparalleled privacy crisis.

Hearing the Masses: The Modern Science of Opinion in the United States

Engineering Society

Sarah E. Igo

2012

Gleaning the opinions of ordinary individuals became the object of an astonishing number of enterprises during the twentieth century: journalists hoping both to pinpoint and expand their readership, corporations to tap into and stoke consumers’ desires, state agencies and political candidates to read and influence the public mood.

“A gold mine and a tool for democracy”: George Gallup, Elmo Roper, and the business of scientific polling, 1935–1955

Journal of the History of Behavioral Sciences

Sarah E. Igo

2006

“Scientific” public opinion polls arrived on the American scene in 1936. Examining the work of opinion surveyors George Gallup and Elmo Roper, this essay tracks the early career of a new social scientific technology, one that powerfully shaped conceptions of “the public.” Pollsters described their craft as a democratic one that could accurately represent the U.S. populace.
