New Books in the History of Science

Standardizing Sex: A History of Trans Medicine (U Chicago Press, 2025) traces the emergence of trans medicine in Scandinavia in the twentieth century, exploring the construction and negotiation of medical expertise among medical professionals, patients, and activists in the media and government bureaucracy. The book combines the author’s analysis of medical records and other archival sources with oral history interviews with former patients, activists, doctors, psychologists, and civil servants. Physician-historian Ketil Slagstad uses the Scandinavian story of sex reassignment to anchor not only the role of the state but also bureaucracy and social rights. Scandinavian countries, he shows, played a foundational role in the emergence of trans medicine internationally. As a result, Standardizing Sex tells a transnational history of medicine that sheds light on a set of relations and problems that continue to impact discussions of trans medicine and trans rights around the world.Slagstad’s sources offer a rare opportunity to explore the emergence of trans medicine in action in the clinic, laboratory, waiting room, and operating room, as well as in the bureaucrat’s office, on the psychologist’s couch, and in the publications and meetings of activist groups. Together, these sources allow for the analysis of the increasingly complex negotiations of nosological criteria, medical knowledge, and medical practices in a formative period for transgender medicine. More generally, the book offers a story about the reshaping of the normal and the pathological in modern societies.

Ketil Slagstad is a research fellow at the Institute for the History of Medicine and Ethics in Medicine at Charité: Universitätsmedizin Berlin.

Since the advent of computers, society has fantasized about conversing with machines. In Divination Engines: Natural Language Processing, Artificial Intelligence, and the Making of Algorithmic Culture
(University of Chicago Press, 2026), Dr. Xiaochang Li shows readers how
that dream both fueled the demand for data and set the stage for
today’s generative AI. 

With original research and clear
explanations, Dr. Li elucidates the origins of what’s
known as natural language processing (NLP) and the heated
twentieth-century debates between computer scientists, linguists, and
communication engineers that shaped today’s technology. Starting with
early devices that recorded, analyzed, and attempted to interpret human
speech, she demonstrates
how computer speech recognition, particularly efforts led by Bell Labs
and IBM, advanced technology by deemphasizing linguistic meaning in
favor of statistical prediction. In other words, researchers gradually
abandoned systems that sought to understand human language, opting
instead for work-arounds
that simply predicted patterns in speech and text data. That solution
became incredibly and surprisingly adaptable. As Dr. Li reveals,
transforming linguistic questions into engineering ones ushered in the
routine operation of search engines, spam filters, and the varied
content sorting and recommendation mechanisms that regulate the access,
circulation, and legitimacy of information across every platform. But
this has all come at the cost of forever requiring copious and
ever-growing amounts of new data.

At its core, Divination Engines
illuminates how the artifacts of human communication—speech, text, and
images—have become both the fodder for and products of computers. This
connection between communication and computation, Li shows, has given
rise to data-driven analytics, machine learning, and today’s algorithmic
culture.

This interview was conducted by Dr. Miranda Melcher whose book
focuses on post-conflict military integration, understanding treaty
negotiation and implementation in civil war contexts, with qualitative
analysis of the Angolan and Mozambican civil wars. You can find
Miranda’s interviews on New Books with Miranda Melcher, wherever you get your podcasts.

This special episode features a short talk Peoples & Things host, Lee Vinsel, gave at the Jefferson Scholars Foundation in Charlottesville, Virginia. The event featured a great mix of historians and Science and Technology Studies scholars and was organized by Jacob Bruggeman, who recently finished his dissertation on the politics of computer hackers at Johns Hopkins University and is now headed to a job at Ohio State University. Thanks to Jacob for putting the event together and hearty congratulations on his accomplishments. In the talk, Vinsel argues that we are missing a synthetic social and economic history of how our adoption and use of digital technologies over the past fifty years has affected everyday life in many social spheres, including work, religion, politics, schools, and family life. He also points to some exemplary scholars who have laid some initial groundwork on these topics and gives some suggestions for primary and secondary sources we can use to do this work. Most of all, the talk is an open invitation to collective work - because doing this project well goes far beyond what any individual can do alone.

In the early nineteenth century, the French naturalist Jean-Baptiste Lamarck proposed the first evolutionary theory of life and, with it, a new science: biology. Yet for centuries, evolutionary theorists have endeavored to discredit Lamarck and his theory of self-transforming organisms, rejecting the idea that animals play an active role in shaping their own evolution. In his lifetime, he was mocked by his adversaries and personally insulted by Napoleon. In this virtuosic melding of biography, history, politics, and science, Jessica Riskin sets out to correct the record. Riskin tells the story of Lamarck’s life and work as an intense struggle between rival forces to answer questions that remain foundational to our modern worldview: What is a living being, and what is science?

New findings suggest Lamarck’s basic claim was, in many ways, right, and a reconsideration of his life and work is long overdue. Denying the agency of living beings has informed two centuries of eugenic policies and environmental destruction, allowing people to regard the living world as so much raw material to shape and exploit for economic, industrial, and imperial gain.Deeply researched, strikingly original, and beautifully written, The Power of Life: The Invention of Biology and the Revolutionary Science of Jean-Baptiste Lamarck (Penguin, 2026) shines a much-needed light on an underappreciated biologist whose radical ideas offered a more inclusive, collaborative, and enlightened approach to science.
