In the autumn of 1888, London’s East End lived through one of the most documented periods of terror in criminal history. An unidentified killer — dubbed Jack the Ripper by the press — murdered at least five women in the Whitechapel district, leaving behind not only a trail of brutal crimes, but also the seeds of what we now call modern criminology.
The context: Victorian London
Whitechapel in 1888 was one of the poorest and most overcrowded districts in Europe. Mass immigration, alcoholism, and prostitution were daily realities. The five victims attributed to the Ripper — Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly — were sex workers living on the most vulnerable margins of that society.
“The killer operated in a city where violence against women was nearly invisible to institutions.”
This structural invisibility explains, in part, why the case was never solved.
The killer’s profile: what we know
The crimes displayed characteristics we now recognise as typical of an organised serial killer:
- Nocturnal attacks in areas familiar to the perpetrator
- Post-mortem mutilations suggesting basic anatomical knowledge
- No robbery as a motive
- Escalating violence between the first and last crime
The Metropolitan Police of the time lacked the systematic tools to analyse this type of offence. The concept of criminal profiling as we understand it today did not yet exist.
The impact on criminology
The case was pioneering in several respects:
First documented forensic techniques. Inspector Frederick Abberline and forensic physician Thomas Bond produced detailed descriptions of the wounds, setting precedents in crime scene documentation.
Psychological profiling avant la lettre. In 1888, Bond drafted what many consider the first criminal profile in history: he described the killer as a solitary man, outwardly respectable, capable of controlling his impulses except during attacks.
Media pressure as an investigative factor. London newspapers published letters supposedly sent by the killer. Although the authenticity of most is questionable, the press’s involvement transformed public perception of crime and forced institutional responses.
The main suspects
Over more than a century, investigators and enthusiasts have pointed to dozens of individuals. The most studied candidates include Aaron Kosminski (a Polish immigrant committed to an asylum in 1891), Montague John Druitt (a barrister found dead shortly after the murders), and Francis Tumblety (an American quack doctor arrested on other charges in 1888).
No accusation has proved conclusive.
An unsolved case, a discipline born
Jack the Ripper was never identified. But his case demonstrated the urgent need for systematic methods to investigate violent crime. Directly or indirectly, it contributed to the development of forensic science, crime scene analysis, and, later, applied criminal psychology.
The mystery endures. The discipline, however, grew.
