Aaron Kosminski vs Francis Thompson: The Outsider We Invented and the Insider We Ignored
It’s remarkable how many still cling to Kosminski — a man barely known, barely present — while overlooking the suspect who fits every line of the evidence. Below is a comparison between Aaron Kosminski, the scapegoat London could live with, and Francis Thompson, the suspect it still can’t face.
The name Kosminski survives not as evidence, but as echo — the faint after-sound of Victorian fear. No first name, no record of arrest, no charges, no trial. Merely a surname scrawled in Sir Melville Macnaghten’s private memo six years after the murders, attached to the words “Polish Jew” and “strong homicidal tendencies.” Those four words — with their casual fusion of ethnicity, class, and pathology — tell us more about the late-Victorian mind than about the man they were pinned to.
Aaron Kosminski, if he was indeed the “Kosminski” meant, was a poor immigrant hairdresser who arrived in London’s East End during a wave of antisemitic migration from Poland and Russia. He lived within the same packed streets as thousands of other Jewish refugees, scratching a living on the edge of destitution. When his mental health failed, he threatened a relative with a knife, was sectioned, and spent the rest of his life in asylums. He never stood trial for any violent crime, never confessed to anything, and never once appeared in police files from 1888. Yet, by 1894, his name had been elevated to the role of London’s most wanted ghost.
The charge was not built on fact but on fear. Sir Robert Anderson’s memoirs later claimed that the Ripper was “a low-class Polish Jew,” identified by a witness who refused to testify “against a fellow Jew.” Chief Inspector Swanson’s margin notes on that book sealed the myth: a convenient circle of untested claims, one official citing another, both confident that silence equalled proof. It was the perfect Victorian echo chamber — closed, self-confirming, and free from scrutiny.
What followed is history’s long act of bad faith. Each generation resurrected Kosminski not from evidence, but from the comfort he provided. He was safely foreign, conveniently poor, and permanently mute. His supposed “solitary vices” — Anderson’s euphemism for masturbation — were transformed into symbols of degeneracy. His madness became motive, his heritage became guilt. No one could verify his presence at a single crime scene, but he looked and sounded like what polite society needed evil to be: alien, incoherent, and beneath them.
Compare that to Francis Thompson, and the dissonance is deafening. Thompson was no faceless immigrant. He was a published poet, educated, English, steeped in theology, medicine, and mysticism. While Kosminski was being scapegoated from the safety of hindsight, Thompson was walking the very streets of Whitechapel in 1888, living rough, sleeping in the same alleys, carrying dissecting knives, writing of divine slaughter and redemption through blood. His own writings describe women as “sacrifices,” his inner voice commanding him to purge and redeem. Where Kosminski’s mind broke into confusion, Thompson’s broke into purpose.
The difference is not just biographical — it’s moral. The Kosminski theory was never an investigation; it was a deflection. It allowed the establishment to preserve its hierarchy of virtue by locating evil in the Other. To admit Thompson would have meant admitting that the killer might have come from its own educated ranks — a man of letters, a devout Christian, a mind torn not by ignorance but by theology. That was unthinkable. Far easier to blame the nameless Jew who could not answer back.
Even the so-called “DNA revelation” of 2014 repeated the old ritual. A dubious shawl, no verified chain of custody, unreplicated results, and a headline that once again pointed the finger at the same impoverished immigrant. The pattern hasn’t changed in 130 years: when doubt grows unbearable, London exiles its monster anew.
By every investigative measure — means, motive, opportunity, and psychological profile — Kosminski fails the test that Thompson meets. The hairdresser owned no surgeon’s tools, had no known fixation on prostitution or purity, and was already descending into catatonia when committed. The poet possessed anatomical knowledge, motive grounded in obsession, and lived amid the killings with no alibi. Yet one is remembered as a suspect, the other as a saint.
That choice is the real confession. It tells us who London wanted its monster to be — and who it could never afford him to be. Kosminski became the mask that hid the mirror. Thompson was the mirror. And in that reflection, the Ripper case remains unsolved only because the city that birthed him still can’t bear to recognize its own face.
