In the autumn of 1888, in the gas-lit slums of Whitechapel in East London, a killer moved through the fog and butchered at least five women in the space of ten weeks. He was never caught. He took organs, taunted the police with letters signed “Jack the Ripper,” and then simply stopped. More than a century later, his identity is still the most debated question in the history of crime — and the case that taught the world to be afraid of the stranger in the dark.

The Autumn of Terror

Whitechapel in 1888 was one of the poorest corners of the British Empire’s richest city. Tens of thousands of people were packed into crumbling lodging houses and unlit alleys, and many women, with no other way to survive, were driven onto the streets at night. It was into this world — overcrowded, desperate, and almost without police lighting — that the killer stepped.

Historians group the killings into what is known as the “canonical five”: Mary Ann “Polly” Nichols, found on August 31; Annie Chapman, on September 8; Elizabeth Stride and Catherine Eddowes, both killed in the early hours of September 30 in what became known as the “double event”; and Mary Jane Kelly, the youngest and the last, found on November 9, 1888. Other Whitechapel murders from the period are sometimes linked, but these five are the ones most often tied to the same hand.

The Murders

The pattern was as distinctive as it was terrible. Most of the victims were attacked on the street in the dead of night, their throats cut and their bodies mutilated. In several cases organs were removed with a precision that led some doctors of the day to suggest the killer had anatomical knowledge — a surgeon, a butcher, or someone who had worked with bodies.

The final murder, of Mary Jane Kelly, was the only one committed indoors, and it was the most savage of all. After Kelly, the killings simply stopped. There was no arrest, no confession, no body — just silence, which in its own way was as frightening as the murders themselves.

The Letters

Much of the legend — including the name itself — came from a flood of letters sent to police and newspapers claiming to be from the murderer. The most famous, the “Dear Boss” letter, was signed “Jack the Ripper.” A postcard called “Saucy Jacky” followed, and a third, the “From Hell” letter, arrived with half of a preserved human kidney.

To this day, no one knows whether any of the letters were genuine. Many investigators believe they were hoaxes, possibly written by journalists eager to keep a terrifying story alive. But the name stuck, and a faceless killer suddenly had a brand — one that has outlived everyone who ever hunted him.

The Investigation

The police of 1888 were fighting almost blind. There were no fingerprints, no blood typing, no DNA — none of the forensic tools that would later become routine. Two forces, the Metropolitan Police and the City of London Police, worked the case, questioning thousands of men and chasing endless tips. When a chalk message that might have been a clue was found scrawled near a bloody fragment of Eddowes’s apron on Goulston Street, a senior officer ordered it wiped away before dawn, fearing it would spark anti-Jewish riots — erasing what may have been the only writing the killer ever left.

Frightened residents formed their own vigilance committees and patrolled the streets at night. The press, hungry for every grisly detail, turned a local horror into a global sensation — arguably the first time a serial murderer became worldwide news.

The Suspects That Never Stuck

In the decades since, the list of named suspects has grown into the hundreds: a barrister who drowned himself shortly after the last murder, a Polish barber, a celebrated painter, even members of the royal household. Modern researchers have tried to pin the case on one man or another using everything from old police memos to DNA claimed to have been recovered from a victim’s shawl — but every such claim has been disputed, and none has ever closed the case.

The truth is that the evidence that might have named him was thin in 1888 and has only decayed since. Barring some extraordinary discovery, Jack the Ripper will almost certainly remain anonymous forever.

Why This Case Still Matters

Jack the Ripper matters less for who he was than for what he created. He was the template for the modern serial killer in the public imagination — the anonymous predator, the taunting letters, the media circus, the city paralyzed by fear. Almost every true-crime story that has gripped the world since carries his fingerprints.

It is worth remembering, too, the cost of that fascination. The “canonical five” were not characters in a Victorian ghost story. They were real women — Polly, Annie, Elizabeth, Catherine, and Mary Jane — most of them poor, many of them mothers, all of them failed by a city that offered them nowhere safe to sleep. The mystery has swallowed their names; the least we can do is say them.

So who was the man in the Whitechapel fog — a doctor, a butcher, a nobody who slipped back into the slums and was never missed? And why, after more than a century, do we still want so badly to give the monster a face?
