Hugh Welch Diamond

Psychiatry Meets Photography in the 1850s

Diamond worked from 1848 to 1858 as a physician in the female department of Surrey County Asylum, where he photographed patients.^*3 Psychiatry at the time still relied heavily on physiognomy, the belief that mental states could be read in the face and bodily expression, and photography was expected to provide a more mechanical and accurate record than drawing. The Met explains that Diamond classified patients according to older psychiatric “types” and treated the photograph as an objective form of representation.^*2 The Musée d’Orsay likewise describes his practice of photographing patients at different moments and comparing changes in appearance with the course of illness.^*9

Diamond as a Photographer

Diamond’s photographic activity extended well beyond psychiatry. He experimented with photography as early as 1839, took part in gatherings of photographers, and became deeply involved in the formation and administration of the Photographic Society, founded in 1853.^*3 The National Portrait Gallery records his work as a founding member, secretary, and journal editor who helped disseminate photographic techniques and also photographed antiquities.^*11 According to the Royal Photographic Society, he served as an editor and secretary of its journal from 1857 to 1868.^*12 His medical aims and his role in the wider photographic community therefore belonged to the same career; the patient portraits cannot be understood only as an isolated branch of medical imaging.

Why Photography Was Needed

In a paper submitted to the Royal Society in 1856, Diamond proposed photographing hospitalized patients at different times and preserving the images as records that physicians and psychological researchers could compare.^*4 The Royal College of Physicians Museum explains that he regarded photography as a “faithful and accurate” medical record and included gesture, hairstyle, and clothing, as well as the face, among the features to be observed.^*5 Photography offered a way to fix a passing expression and compare the same patient across intervals of time. A Cambridge history-of-medicine account likewise places the photographing of female patients at the intersection of clinical work and a new technology.^*6

Poses and Props Complicate Claims to Objectivity

The patient portraits record hats, shawls, chairs, birds, purses, and the placement of hands alongside the faces that physicians treated as diagnostic clues. A 2022 study argues that these photographs pursued scientific documentation while also drawing on long-standing images of madness and contemporary case descriptions; the sitter could be made to exemplify a psychiatric type and still appear as a distinct person.^*7 As The Met notes, the expression of one sitter can be read in several ways—as a smile, a defiant attitude, or a sign of recovery—and the photograph alone cannot establish the period’s diagnosis.^*1

Showing Patients Their Photographs: Therapeutic Aims and Medical Authority

Diamond believed that photographs might help patients recognize changes in their own condition and could have a therapeutic use, although Getty also notes that no actual effect can be demonstrated.^*3 Many surviving images lack complete information about patient names, consent, or diagnosis, while the authority to decide when to photograph and how the images were managed remained largely with the institution and physician. A 2025 article in the Transactions of the Royal Historical Society treats participation by viewers, reenactment, empathy, and collaboration with disabled people as ethical questions in the present-day reuse of historical asylum photography.^*8 Wellcome also preserves portraits of patients, images of Diamond himself, scrapbooks, and related publications, allowing the photographs’ original medical functions to be studied alongside their later histories of collection, research, and display.^*13

Using Photographs for Diagnosis, Comparison Over Time, and Readmission Records

Diamond’s 1856 paper assigns several functions to patient photography. A seventeen-page manuscript preserved by the Royal Society proposes repeated photographs during hospitalization so that physicians and psychological researchers could compare a patient’s condition at different stages.^*22 A full later reprint records his claim that an earlier portrait helped a physician recall the history and treatment of a patient who returned after discharge, and that showing photographs to patients themselves might have therapeutic value.^*24 He treated photographs as material for identifying types, records for comparison over time, case documents that aided a physician’s memory, and objects to show to patients. Contemporary medical-historical research also stresses that the portraits were arranged through clothing and pose and drew on existing literary and visual types such as Ophelia.^*23 The range of intended uses and the degree of staging make clear why a single photograph could not objectively determine a patient’s mental state.

Patient Portraits at Surrey County Asylum

In The Met’s patient portrait from 1850–58, a seated woman turns her body slightly while facing the camera against a nearly blank background. No diagnosis survives in the object record, and the museum cautiously lists identification, diagnosis, and the documentation of a stage in the illness among several possible uses.^*1 Another portrait from 1850–55 makes explicit that the historical system of psychiatric “types” on which such classification depended is no longer accepted.^*2 The value of these photographs today lies less in preserving a correct diagnosis than in preserving evidence of a medical system that treated the face as legible data.

Portrait de folle

The Musée d’Orsay’s Portrait de folle, dated about 1852–54, is an albumen print from a wet-collodion glass negative. A dark background, the seated woman’s hands, and her gaze dominate the image.^*9 The museum’s artist record gives Diamond’s dates as 1809–1886.^*10 The National Portrait Gallery gives 1808–1886.^*11 Getty ULAN also uses 1809 as the preferred birth year, so major institutions do not agree on the date.^*16 This page therefore retains the uncertainty as 1808/09–1886.

Photographic Work Beyond Medicine

Diamond also participated in the reproduction of sculpture and in photographic-club publishing. Copy of a Bust of Her Majesty Queen Victoria is an albumen print from 1857 that reflects an interest in reproduction and antiquities far removed from the patient portraits.^*18 The Photographic Album for the Year 1857 brought together work by Diamond and many other photographers, demonstrating a culture in which photographs circulated through clubs and associations, not solely as individual works.^*19 Getty Research’s authority record likewise identifies him simultaneously as physician, photographer, and antiquarian.^*16

Beyond the Label “Father of Medical Photography”

Diamond is often called the “father” of psychiatric photography, but that label does not account for his sustained involvement in photographic societies, technical education, antiquarian work, and general portraiture. The National Portrait Gallery treats his patient photographs and his work for photographic organizations within the same biography.^*11 Wellcome preserves portraits of Diamond, group photographs of photographic-society members, and related books, allowing him to be followed as a participant in a broader photographic community.^*14 The patient photographs did not remain confined to the asylum. Diamond administered photographic organizations, taught techniques, and exhibited patient images during the same period, so photographs produced as medical records also entered spaces of photographic viewing and evaluation. The National Science and Media Museum notes that these portraits were shown at photographic exhibitions and drew mixed responses because they sat uneasily between art and science.^*15 That unstable reception was already built into the photographs’ dual life as medical records and portraits.

The Royal Society did not publish the complete manuscript at the time, printing only a short abstract in its Proceedings.^*22 Many of the detailed claims now associated with Diamond are known through the preserved manuscript and later full reprints. Present-day accounts of him as a pioneer of medical photography therefore need to distinguish his photographic work of the 1850s from the later preservation and republication of both his text and his images.

Reuse of Patient Portraits and the Ethics of Medical Photography

When patient photographs are organized only by diagnostic category, details that belong to portraiture—clothing, expression, props, and posture—can disappear from view. Getty’s record for Seated Woman with a Bird preserves even the fact that the sitter holds a bird.^*17 The study Doctor Diamond and His Portraits of the Insane, preserved by Wellcome, shows how these images have repeatedly been reedited within later histories of medicine and photography.^*21 Educational material on portraiture from the Musée d’Orsay also treats Diamond’s patient photographs as examples of nineteenth-century portrait photography, showing that they are received as portraits as well as through their medical origins.^*20 The 2025 Royal Historical Society article’s discussion of participation and viewer responsibility in the reuse of historical asylum photographs also makes it necessary, when these images are exhibited or discussed today, to distinguish their origin as diagnostic material from their appearance as portraits.^*8

Psychiatric Patient Photography and Diamond’s Place in Photographic History

Diamond introduced the techniques of portrait photography into observation and case recording in a psychiatric institution and proposed photographing the same patient at different times to compare outward changes. His 1856 manuscript describes repeated photography, its use as an aid to memory when a patient was readmitted, and the idea of showing photographs to patients themselves.^*22 At the same time, the portraits demonstrate that the camera did not diagnose illness automatically. Gaze, posture, clothing, and props were shaped by choices made during the sitting, and the same expression could invite more than one interpretation.^*1 An early attempt to use photography for medical classification and the difficulty of reducing a photographed person to that classification remain visible within the same images.
