Born on September 11, 1865, Aaron Kosminski grew up in Klodawa, near Warsaw, the youngest of seven children.
When he was eight years old his father died and his mother remarried. Records suggest the young man may have suffered sexual abuse.
In 1882, the family fled to London to escape anti-Semitism in Poland and settled in the East End, where Kosminski allegedly became a serial killer at the age of 23.
At the time of the Ripper murders, the head of London CID, Dr. Robert Anderson, already suspected him of being the perpetrator.
Confidential police reports revealed that police believed Kosminski had “a great hatred towards women, especially the prostitute class, and had strong homicidal tendencies.” However, the police had no hard evidence and feared accusations of anti-Semitism.
In 1890, Kosminski suffered a suspected attack of schizophrenia and threatened his sister with a knife.
The following year he was committed to the Colney Hatch asylum in north London.

The Whitechapel murders were truly sickening. Each of the five female victims was savagely disfigured and their blood spilled onto the cobblestones of Victorian London.
He died 28 years later at Leavesden Asylum, Hertfordshire.
His older brother, Isaac, was a wealthy tailor who moved to London in April 1870 before changing his name to Abrahams.
Ripper author and researcher Russell Edwards has discovered photographs showing Isaac dressed as a member of the Lodge of the Freemasons of Israel, which may explain why Kosminski escaped justice.
He believes Kosminski’s mutilation of the victims was related to Masonic blood oaths that refer to the cutting of throats and the removal of certain body parts.
Edwards recently used photographs of Kosminski’s family and facial reshaping technology to create a composite of what the Ripper suspect looked like in real life.
