Herschel Albert Prins (1928–2016) was a British professor of criminology. His career spanned over 60 years in work pertaining to forensic psychiatry, and his appointments included positions at the universities of Leeds, Loughborough, Leicester and Birmingham. His roles included HM probation inspectorate, parole board engagement, and involvement in mental health review tribunals and the mental health act commission. He worked with people with malicious activity, antisocial and disinhibited behaviour, unusual sexual deviations and people who behaved dangerously.

During the 1980s Prins was on the editorial board of the Howard Journal of Criminal Justice. In the 1990s he chaired three inquiries into the care and management of patients that had been offenders, including the 1991 independent inquiry into the death of Orville Blackwood, the findings of which were published in the Report of the committee of inquiry into the death in Broadmoor Hospital of Orville Blackwood, and a review of the deaths of two other Afro-Caribbean patients: "big, black and dangerous?" (1993).

By 2007, he had written many articles in The Journal of Forensic Psychiatry & Psychology and several books. The Herschel Prins Centre in Leicester, opened in 2001, is named for him.^[1][2]

Prins' career, much of which is detailed in his book Mad, Bad and Dangerous to Know: Reflections of a Forensic Practitioner (2010),^[3] covered over 60 years in work pertaining to forensic psychiatry, and his appointments included university positions, HM probation inspectorate, parole board engagement, and involvement in mental health review tribunals and the mental health act commission.^[1][4] He worked with people with malicious activity, antisocial and disinhibited behaviour, unusual sexual deviations and people who behaved dangerously.^[2][5]

Early in his career he supervised people on probation at Three Counties Hospital, Arlesey, and this led to an interest in mental illness in offenders.^[4] After taking evening classes, he gained admission to the London School of Economics to study psychiatric social work.^[6][4] Subsequently, he was posted to Stamford House, a remand home for boys, where he met Peter Duncan Scott, a forensic psychiatrist who influenced him enough that Prins later dedicated his first edition of Offenders, Deviants, or Patients? (1980) to him.^[4] Later, he joined the Home Office, where he organized courses for trainee probation officers, with the engagement of psychiatrists, on mental health factors of delinquency.^[4] He had also taught at the North Western Polytechnic in Kentish Town, north London, and held an appointment as the Inspectorate of Probation.^[6] He was appointed lecturer at Leeds University's social work faculty before taking a teaching appointment as head of the University of Leicester's school of social work, which he held between 1981 and 1984.^[6][7] At Leeds, he had been on the management committee of an aftercare hostel for adult prisoners, and on a local review committee (part of the parole system) at the prison in Leeds.^[4] In the 1980s he was also on the editorial board of the Howard Journal of Criminal Justice.^[2] Prins became professor at Loughborough University's Midlands Centre for Criminal Justice, while holding an honorary chair in criminology and forensic psychology at Birmingham University.^[4]

In 1999, Mentally Disordered Offenders: Managing People Nobody Owns, edited by David Webb and Robert Harris, was compiled by his peers.^[2]

By 2007, he had written many articles in The Journal of Forensic Psychiatry & Psychology and several books.^[4] In 2008, he was made honorary professor of the University of Leicester.^[7]

Among high profile cases he wrote about were Peter Sutcliffe^[14] and Harold Shipman.^[15]

Prins' 2013 publication, Psychopaths: an Introduction, was based on his huge experience and includes a quote by judge John Geoffrey Jones on classifying criminal deeds.^[16]

Herschel Prins was born in Finchley, north London in 1928, into a Jewish family, son of Louis Prins, a social worker, and Cissie (née Cohen).^[17][6] His parents died when he was a teenager, following which he was cared for by family.^[6] He left school at the age of 16 years.^[6] In 1958, he married Norma (née Cree). They had two children.^[6] Following retirement he continued lecturing as professor of forensic criminology at the university at Loughborough and as honorary professor at the University of Leicester.^[6] Prins died in 2016, five years after Norma's death.^[6]
