15 Historical Female Killers: Court-Convicted Cases from the Shadows of History
In the annals of true crime, female perpetrators often evade the spotlight reserved for their male counterparts, yet their stories are no less harrowing. These women, driven by greed, revenge, or delusion, turned domestic spaces into chambers of death, frequently employing insidious methods like poison that left victims suffering in silence. From 18th-century England to early 20th-century Europe and America, this list examines 15 historical female killers whose guilt was affirmed through verified court records. Each case honors the victims—nameless innocents, family members, and vulnerable souls—whose lives were cut short, reminding us of the profound tragedy behind these convictions.
What unites these killers? A disproportionate reliance on arsenic and other toxins, motives rooted in inheritance or insurance, and trials that captivated publics hungry for scandal. Drawing from trial transcripts, coroners’ reports, and historical accounts, we delve into their backgrounds, crimes, investigations, and fates. These stories underscore the rarity of female homicide—less than 10% of killers historically—while analyzing the societal blind spots that allowed their rampages.
Respectfully, we approach these narratives not for sensationalism, but to illuminate justice’s slow grind and the enduring pain of loss for survivors.
1. Mary Blandy (1720-1752, England)
Born into genteel Scottish society, Mary Blandy was the only child of a prosperous lawyer in Henley-on-Thames. Educated and poised, she dreamed of marriage to Captain William Cranstoun, a bigamist Scotsman promising riches. Her father opposed the union, prompting a desperate plot.
Over months in 1748-1749, Blandy administered arsenic-laced “Scotch pebbles” tea to her father, Francis Blandy, a respected figure whose agonizing death from convulsions drew suspicion. Symptoms matched poisoning; exhumation revealed arsenic. Mary claimed ignorance, saying Cranstoun supplied the powder to “powders” her affections.
Her 1752 Oxford trial, marked by dramatic testimony—including her own coherent defense—lasted nine hours. Convicted of willful murder, she was hanged at Oxford Castle, her final words pious. The case, detailed in pamphlets, highlighted class privilege’s limits and poison’s stealth, claiming one victim but suspected more.
2. Elizabeth Brownrigg (1724-1767, England)
A London midwife of middling means, Elizabeth Brownrigg ran a workhouse with husband James and son John. Known for cruelty, she exploited parish apprentices under the guise of charity.
In 1767, 14-year-old Mary Clifford, bound from St. Dunstan’s workhouse, endured savage beatings with whip and broom. Brownrigg starved her, chained her in a coal hole, and bashed her head, leading to Mary’s death from infected wounds. Fellow apprentice Mary Jones testified to the horrors.
Arrested after Mary was found collapsed, Brownrigg fled to a pub but was captured. Her Old Bailey trial exposed workhouse abuses; convicted of murder, she was hanged at Tyburn alongside son John. James received a lighter sentence. The case spurred reforms in apprentice care, honoring Mary’s needless suffering.
3. Sarah Metyard (1706-1768, England)
Sarah Metyard, a widowed mantua-maker in London, lived with daughter Sarah (1733-1768), operating a dress shop that doubled as a prison for apprentices.
In 1758, 13-year-old Mary Jones escaped after beatings but was recaptured. The Metyards starved her in a garret, chaining her until she perished from exhaustion. They concealed the body in a trunk, later dumping it. When another apprentice inquired, they fabricated lies.
Exposed in 1768 by a former lodger, their Old Bailey trial featured grim evidence of the garret’s squalor. Both convicted of murder—Sarah senior for orchestrating, junior for aiding—they were hanged together at Tyburn. This rare mother-daughter duo’s case illuminated apprentice exploitation in 18th-century London.
4. Mary Ann Cotton (1832-1873, England)
The archetypal “black widow,” Mary Ann Cotton, a miner’s wife from County Durham, married four times, birthing 13 children amid suspicious deaths.
From 1852-1872, she poisoned at least 21 victims—including husbands, children, and a mother-in-law—with arsenic in tea or porridge, collecting insurance. Quick “gastric fever” deaths funded her lifestyle. Suspicion arose with stepson Charles’ 1872 demise.
Exhumed bodies confirmed arsenic; her 1873 trial at Durham Assizes convicted her of one murder (son Charles Edward). Hanged at age 40, she protested innocence to the end. Estimates suggest up to 21 victims, her motive pure avarice, leaving orphans in grief.
5. Sarah Chesham (died 1851, England)
A Hertfordshire laborer’s wife, Sarah Chesham turned to arsenic after family deaths, amid rural poverty.
In 1847 and 1851, she poisoned two sons and stepson with arsenic-laced food, mimicking cholera. Neighbors noted her calm amid funerals. A third son’s survival led to inquiry.
Her 1851 Hertford trial, the first English woman tried for poisoning a child, convicted her via medical evidence. Hanged publicly, she became the last woman executed at Bedford. Dubbed “Sarey” the poisoner, her case reflected desperation’s dark turn.
6. Catherine Wilson (1822-1862, England)
Irish-born nurse Catherine Wilson preyed on ailing lodgers in London, posing as caregiver.
From 1856-1862, she poisoned at least five—husband, lover, and patients—with liquid arsenic, hastening deaths for belongings. Victim Mrs. Soames’ screams alerted police.
Trials in 1862 at Old Bailey convicted her of one murder; she admitted more. As the last woman hanged in England (Newgate), her bravado faded on the scaffold. Her methodical mercy killings exposed vulnerabilities in Victorian healthcare.
7. Amelia Dyer (1829-1896, England)
Baby farmer Amelia Dyer advertised adoptions, but her Bristol home was a death trap for illegitimate infants.
In 1896 alone, she starved and strangled at least six babies, dumping bodies in the Thames. Records showed hundreds over decades, feeding them opium-laced paregoric.
Found with strangled Evelyn Marné, Dyer’s 1896 trial convicted her swiftly. Hanged at Newgate, she was likely Britain’s worst murderer (400 victims?). Reforms to adoption laws honored the voiceless innocents.
8. Kate Webster (1849-1879, England)
Irish servant Kate Webster, illiterate and violent, worked for widow Julia Martha Thomas in Richmond.
In 1879, after a quarrel, Webster strangled Thomas, dismembered her with a razor, boiled flesh, and sold fat as “pork”. Bones surfaced in the Thames.
Captured in Ireland, her Old Bailey trial featured gruesome testimony. Convicted, she was hanged at Wandsworth. The “Richmond Murder” shocked London, Webster’s butchery unprecedented for a woman.
9. Maria Swanenburg (1839-1915, Netherlands)
Dutch “Zwarte Mietje” (Black Mietje), Maria Swanenburg nursed neighbors in Leiden.
From 1880-1888, she poisoned 27 with arsenic in coffee or milk, targeting savings. Five direct murders, 23 attempts.
Her 1889 trial convicted her of three murders; sentenced to life in Dolle Mina prison, she died there. Motive: theft. Her case, Europe’s deadliest female poisoner then, prompted toxicology advances.
10. Florence Maybrick (1862-1941, England)
American-born socialite Florence Maybrick married Liverpool cotton broker James.
In 1889, amid affair suspicions, she poisoned James with arsenic from flypaper, in meat and drink. His “gastritis” death matched symptoms.
The sensational 1889 St. Helens trial convicted her despite diary disputes; sentenced to death, commuted to life. Released 1904, pardoned 1904. Victims’ families decried injustice claims.
11. Louisa Collins (1842-1889, Australia)
Sydney laundress Louisa Collins married twice, both husbands dying oddly.
In 1886-1887, she arsenic-poisoned Michael Collins and lover Michael Goodwin, blaming “diarrhea”. Children testified to her dosing.
Two 1889 trials convicted her; hanged at Darlinghurst, last woman in Sydney. Her calm demeanor chilled observers, case fueling anti-death penalty debate.
12. Darya Saltykova (1730-1801, Russia)
Noblewoman Darya Saltykova ruled her estate tyrannically near Moscow.
From 1759-1768, she flogged 138 serf women to death, often naked, with logs or flames. Bodies dumped in ravines.
Petitioned by serfs, Catherine the Great’s 1768 investigation led to trial; convicted of 38 murders, she endured public whipping then lifelong monastery confinement. A feudal horror.
13. Vera Renczi (c.1900s-1930s, Romania)
Bucharest beauty Vera Renczi obsessed over lovers’ fidelity.
By 1932, she poisoned 35 men—husbands, fiancés—with arsenic wine, pickling bodies in zinc coffins in her cellar.
Discovered after a lover’s brother investigated, her 1932 trial convicted her; life in Poarta Albă prison. Jealousy-fueled necrophilia shocked Europe.
14. Leonarda Cianciulli (1894-1970, Italy)
“Soap-Maker of Correggio,” Leonarda Cianciulli feared losing sons to war.
In 1939-1940, she lured three women, axed them, boiled flesh into soap, and baked cakes from blood/ash, “gifting” to neighbors.
Confessing in 1946, her trial convicted her of three murders; 30 years hard labor, released to asylum. Superstition drove her cannibalistic rituals.
15. Tillie Klimek (1876-1936, USA)
Chicago psychic Tillie Klimek predicted neighbors’ deaths—then caused them.
From 1914-1921, she arsenic-poisoned five husbands, four dogs, and neighbors, boasting premonitions.
1923 trial convicted her of one murder (husband Joseph Kupczyk); 25 years Joliet Prison, died there. Her “evil eye” claims masked methodical malice.
Conclusion
These 15 women, spanning centuries and continents, reveal stark patterns: arsenic’s prevalence (over half used it), domestic intimacy with victims, and financial or emotional motives. Court records—from Old Bailey ledgers to Russian edicts—affirm their guilt, often after exhumations revolutionized forensics. Yet, each tragedy underscores victims’ stolen futures: children, spouses, the vulnerable. While female killers remain outliers, their cases advanced laws on poison sales, child welfare, and serf rights. In remembering, we honor the lost and affirm justice’s vigilance against hidden horrors.
