The Ogress of Reading: Britain's Most Prolific Serial Killer
How Amelia Dyer murdered hundreds of infants over three decades while posing as a caregiver
Published June 6, 2025

Quick Facts
On 4 April 1896, police arrested Amelia Elizabeth Dyer in Reading, England, uncovering one of the darkest criminal enterprises in British history. The woman known as the "Ogress of Reading" had operated her deadly scheme for over thirty years, claiming the lives of infants across Bristol, Cardiff, London, and Reading—with estimates ranging from 300 to 400 victims.
Born on 27 November 1837 (though some sources cite circa 1839) in Pile Marsh, near Bristol, Dyer trained as a nurse before discovering a far more sinister profession. She began her career as a "baby farmer"—a practice common in Victorian England where unmarried mothers, desperate to escape scandal and unable to afford childcare, would pay women like Dyer to take their infants. These mothers were promised care, adoption, and a fresh start. What they received instead was a death sentence.
Dyer's method was simple but devastating. She advertised her services in newspapers under various aliases—Annie Dyer, Anne Harding, Mrs. Thomas, Mrs. Smith, and others—targeting vulnerable women seeking discretion. Once she received payment and possession of the child, she would systematically neglect or murder them through starvation, opium administration, or strangulation. The bodies would be wrapped, bagged, and discarded in rivers across England.
Timeline
Dyer's work as a "baby farmer" begins
Around 1869, Amelia Dyer begins taking in infants for payment – a practice she continues for almost three decades.
Body remains found in the Thames near Caversham
In March and April 1896, body remains are discovered in the Thames in the Caversham area near Reading, Berkshire, and a police investigation is launched.
Trial at the Old Bailey in London
In May 1896, the case against Amelia Dyer is heard at the Central Criminal Court (Old Bailey) in London. She is charged with the murder of Doris Marmon.
Amelia Dyer executed at Newgate Prison
On 10 June 1896, Amelia Dyer is hanged at Newgate Prison in London after being found guilty of murder and sentenced to death.
For years, her crimes went undetected. The women who had surrendered their children dared not come forward; shame and fear kept them silent. But Dyer's luck ran out when the body of an infant named Doris Marmon surfaced in the River Thames, still in its bag. Doris's mother, Evelina Edith Marmon, a 25-year-old unmarried woman and devout Christian, had paid Dyer to care for the child. The discovery would prove fatal to Dyer's enterprise.
When arrested, Dyer attempted suicide, a pattern that would characterize her life. She had a documented history of mental disturbance, including previous suicide attempts by drowning and throat-cutting. Her trial, held in May 1896, became a sensation across Victorian society. The defense argued that her family history and prior suicide attempts demonstrated insanity, yet prosecutors focused on a simpler motive: greed. Dyer had profited handsomely from boarding fees, receiving money from desperate mothers for infants she had no intention of keeping alive.
The jury found her guilty of the murder of Doris Marmon. Before her execution, Dyer penned a letter to police acknowledging her crimes and stating she would "answer to the Maker" for her actions. She took care to exonerate her daughter Mary Ann Palmer and her husband Arthur Ernest Palmer, suggesting they had not been complicit in her enterprise.
On 10 June 1896, Amelia Dyer was hanged at Newgate Prison. Her case sent shockwaves through Britain and prompted reforms in childcare regulation. She earned multiple epithets—the Baby Butcher, the Angel Maker, the Ghoul—but history remembers her primarily as the Ogress of Reading. For decades, her waxwork figure was displayed in Madame Tussauds Chamber of Horrors, a ghastly monument to one woman's capacity for calculated cruelty. She remains a candidate for the world's most prolific serial killer, a distinction that speaks to the scale of her depravity and the tragic vulnerability of the infants left in her care.
