Aaron Kosminski (born Aron Mordke Kozmiński; 11 September 1865 – 24 March 1919) was a Polish-born barber and immigrant to England who became one of the best-known suspects in the Jack the Ripper murders. He lived in Whitechapel in London and was later institutionalised in an asylum. His possible involvement remains disputed, and modern claims that DNA proved his guilt are not universally accepted.

Early life

Kosminski was born in 1865 as Aron Mordke Kozmiński in Kłodawa, in Congress Poland. He later moved to England and lived in the East End of London.

Whitechapel and Jack the Ripper suspicion

Kosminski worked in Whitechapel during the period of the 1888 murders attributed to Jack the Ripper. He was later identified by some investigators and writers as a leading suspect, though no court conviction ever occurred.

Institutionalisation and later life

In 1891, Kosminski was confined to an asylum after an incident involving a threat to his sister with a knife. He spent time in Colney Hatch Lunatic Asylum and then Leavesden Asylum, where he died in 1919.

Modern claims and debate

In the 2010s and 2019, some authors and researchers argued that DNA evidence linked Kosminski to the murders. Those claims have been contested, and the identification remains controversial among historians and forensic experts.
