Anthropometric and degenerative traits as a scientific basis for prisoner classification
01
What institutions accepted
Belgian prison anthropology treated body measurements, morphology, hereditary and acquired 'degeneration', mental traits and family history as scientifically meaningful inputs for diagnosing and classifying offenders, and institutionalised them in standardised dossiers intended to guide individualised prison classification and treatment.
02
What the evidence supports now
Body measurements, morphology and hereditary 'degeneration' markers do not provide a scientifically valid diagnosis of criminality; the State Archives of Belgium describes the period's concepts as scientifically obsolete. Change inside the prison system was gradual: psychological and sociological factors gained priority after the Second World War, and Étienne De Greeff's 1952 report judged anthropometric measurements minimally useful and biological, temperament and hormonal classifications superfluous, but anthropological dossiers and services continued in revised form.

Impact
Louis Vervaeck opened Belgium's first prison anthropology laboratory in Brussels with ministerial approval in 1907. In 1920 the Ministry-backed Penitentiary Anthropology Service established laboratories in ten prisons and introduced standardised files recording bodily measurements, family and hereditary history, health, education, social faculties, mental resistance and a final diagnosis. More than 9,000 Saint-Gilles files survive from 1920–1957, but only 3–7% of the prison's registered prisoners were actually examined. After the war the service gave greater weight to psychological and sociological factors. De Greeff's proposed medico-psychological dossier was not implemented uniformly, a revised anthropological dossier appeared in the early 1960s, and local anthropological services were replaced in 1997.
Context
Vervaeck was not a simple follower of Cesare Lombroso. His classification combined hereditary, biological, psychological and environmental factors, and he rejected a crude single-cause determinism. The institutional error was the scientific weight assigned to anthropometry and hereditary-degeneration categories, not every element of early Belgian rehabilitative criminology.
Vervaeck's 1907 tattoo study illustrates the breadth of the data collected, but it does not establish the later national classification system. In that study he found no apparent relationship between tattooing and heredity, degeneration, insanity or criminality and warned against inferring moral or psychological character from tattoos.
The 1952 report documents an internal methodological critique, not a completed service-wide repudiation. Uniform adoption of De Greeff's replacement dossier proved impossible; revised anthropological dossiers remained in use, and the local services retained that name until their replacement by a psychosocial service in 1997.

Institutional episode 01
Belgium
Western Europe
Belgium made criminal anthropology part of prison administration. The Ministry-backed service created standardised diagnostic dossiers and classified examined prisoners through bodily, hereditary, psychological and social observations. Its programme intended those diagnoses to guide individualised classification and treatment. Actual coverage was limited at Saint-Gilles, where only 3–7% of registered prisoners were examined despite the survival of more than 9,000 dossiers. The postwar shift away from anthropometry was gradual and remained institutionally incomplete in 1952.

Institutional context
After ministerial approval, Vervaeck opened an anthropological laboratory in a Brussels prison in 1907. His model classified offenders through a broad medical and psychiatric examination, anthropometry, and questions about hereditary, social and criminological background. In 1920 the Ministry-backed Penitentiary Anthropology Service established laboratories in ten prisons and introduced standardised dossiers. The programme was designed to make prison classification and treatment individual to the diagnosed prisoner. After the war, practitioners increasingly prioritised psychological and sociological factors; De Greeff's 1952 report called anthropometric measures minimally useful and biological, temperament and hormonal classifications superfluous.
Why this persisted
ClassificationMinistry-backed prison laboratories recorded bodily, hereditary, psychological and social observations in standardised anthropological dossiers, classified examined prisoners, and intended the diagnoses to guide individualised institutional placement and treatment.
How correction happened
Partially corrected1952–1997
Action: De Greeff's 1952 internal report reduced anthropometry to minimal utility and rejected biological, temperament and hormonal classifications as superfluous; the service then changed its dossiers gradually, and local anthropological services were replaced by a psychosocial service in 1997.
The report was a specific internal methodological rejection, but it did not produce a uniform or immediate institutional replacement. A new anthropological dossier appeared in the early 1960s, and anthropological dossiers and local services continued until 1997. The surviving sources do not document a single formal repudiation of the older theory by the Ministry or service.
Consequences
- Detailed bodily, hereditary, social and psychological data were collected from prisoners who received an examination
- Offenders were classified through categories that combined heredity, environment and scientifically obsolete degeneration concepts
- Dossiers were intended to support individualised classification and treatment, and later reports were sent to prison management
- Medical diagnosis acquired a larger role in Belgian prison administration and social-defence proposals
- More than 9,000 Saint-Gilles dossiers survive from 1920–1957, although only 3–7% of registered prisoners there were examined

This primary study illustrates an early prison questionnaire that recorded heredity, degeneration, mental state, criminality, recidivism and bodily or social information. It is not evidence for the later national service: the study also reports no apparent association between tattooing and heredity, degeneration, insanity or criminality and cautions against inferring moral or psychological character from tattoos.
