This tome is one of those rare histories where a seemingly narrow subject opens into vast questions about empire, science, and the very meaning of identity.
Finished this morning, the book left me with a curious sensation: the way a fingerprint, at once minuscule and unique, can also become an emblem of power structures stretching across centuries and continents.
Sengoopta is meticulous in showing how fingerprinting emerged less from the eureka moment of a lone genius and more from the messy entanglement of colonial bureaucracy, anxieties about fraud, and a desire to “scientifically” know and classify Indian subjects. The act of pressing an inked finger onto paper becomes, in his telling, not just a bureaucratic tool but a deeply political act.
Compared to other histories of forensic science, Sengoopta’s work feels strikingly specific in its focus yet global in implication.
Jay D. Aronson’s Genetic Witness: Science, Law, and Controversy in the Making of DNA Profiling (2007), for instance, takes us into late 20th-century courtrooms where DNA evidence was transforming notions of truth and justice.
While Aronson emphasises the legal controversies and the scientific debates about reliability, Sengoopta’s narrative is rooted in the imperial project itself: how governance in colonial India actively shaped what counted as “reliable” identification in the first place. In this sense, fingerprinting is less about science catching up with truth and more about science serving the needs of rule.
Similarly, Alison Bashford’s Imperial Hygiene (2004) comes to mind as a companion text—another exploration of how the empire used biological and bodily markers to surveil, categorise, and control populations. Bashford deals with sanitation and segregation, while Sengoopta looks at fingertips, but both reveal the same dynamic: the colonial body rendered into data.
Where Bashford shows us the body as a site of contagion and purity, Sengoopta presents the body as a site of authenticity and deception. Together, these works illustrate how colonial science was never disinterested but always already implicated in the maintenance of order.
One of the book’s most compelling contributions is the recovery of Indian figures like Azizul Haque and Hem Chandra Bose, whose intellectual labour was instrumental to Edward Henry’s fingerprint classification system.
Reading this after having browsed Simon A. Cole’s Suspect Identities: A History of Fingerprinting and Criminal Identification (2001), the contrast is sharp. Cole, though insightful on the broader global trajectory, remains somewhat Eurocentric, whereas Sengoopta insists on India as the crucible of innovation.
It is in Bengal’s offices and prisons, not merely London’s laboratories, that fingerprinting was born. In highlighting this, Sengoopta reminds us of how “universal” science often has parochial origins, coloured by race, empire, and ideology.
What lingers most after finishing the book is how profoundly it reshapes the notion of identity. Before fingerprints, identity in India was enmeshed in caste, kinship, land, and community testimony.
Afterward, identity could be distilled to the whorls and ridges on skin, indifferent to reputation or social networks. It’s a transition that resonates with our own moment of biometrics, Aadhaar databases, and genetic surveillance.
Reading Sengoopta after works like Richard Saferstein’s textbooks on forensic science, which tend to present technologies as neat, objective, and value-free, you realise just how misleading such neutrality is. Technologies of identification are never innocent; they bear the imprints of the societies that birthed them.
By the final chapter, one feels that Sengoopta has achieved something more than a history of fingerprinting. He has crafted a genealogy of how science entwines with power, how a ridge of skin can mirror the architecture of empire.
In this way, Imprint of the Raj stands shoulder to shoulder with the likes of Cole, Aronson, and Bashford, while also carving its own distinct path by rooting the narrative in the Indian colonial archive.
It’s a reminder that every “objective” forensic method has a story, and often that story begins in the shadows of domination.
