Jack the Ripper murders

1888Contested

In 1888 an unknown killer murdered at least five women in London's Whitechapel district. Called Jack the Ripper after a letter sent to a news agency, the killer was never caught.

The story

Between August 31 and November 9, 1888, five women were murdered in or near Whitechapel, a poor district in the East End of London: Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes and Mary Jane Kelly. All were women living in deep poverty, and most of the bodies were mutilated in ways suggesting the killer had some knowledge of anatomy. Other murders in the area that year and the next are sometimes linked to the same person. Police from Scotland Yard and the City of London force made house-to-house searches and questioned hundreds of people, but no one was charged.

The case became a sensation because of London's booming popular press, which printed lurid daily coverage, and because of letters claiming to come from the killer. One sent to the Central News Agency in September and signed Jack the Ripper gave the murderer his name, though many historians think it was written by a journalist. Officials' private notes named suspects, including the Polish barber Aaron Kosminski and the barrister Montague Druitt, but none was ever proved. Writers have since proposed more than a hundred suspects, from a royal physician to the painter Walter Sickert, and the case remains unsolved.

Why it mattered

  • Public anger over the police failure fed reforms in policing and pressure to improve housing and conditions in the East End.
  • The case created the modern template of the serial killer in popular culture, from fiction and film to true crime.
  • Claims to have solved the case, including DNA studies, have become a running test of how evidence in historical mysteries should be judged.

Contested history

Consensus: An unidentified killer murdered at least five women in Whitechapel, London, in 1888, and police never charged anyone. Officials privately suspected several men, and modern claims to have identified the killer remain unproven.

The five canonical victims were killed by the same personDebated
Police at the time and most researchers link the five by method and location, but some argue Elizabeth Stride or Mary Jane Kelly may have been killed by someone else, and others add further victims.

DNA from a shawl identifies Aaron Kosminski as the killerMinority view
A 2019 study by Jari Louhelainen and David Miller reported mitochondrial DNA matching relatives of Kosminski and Catherine Eddowes. Critics note the shawl's provenance is doubtful, the data were not fully published, and mitochondrial DNA cannot single out one person.

The painter Walter Sickert was Jack the RipperSpeculation
Novelist Patricia Cornwell argues this from letters, paintings and DNA tests on Sickert's correspondence. Most Ripper historians reject it, noting evidence that Sickert was in France during several of the murders.

This theory, popularized in the 1970s, relied on claims later withdrawn by one of its main sources, and no documents support it.
