6 Underrated Serial Killers That History Overlooked
In the annals of true crime, names like Ted Bundy and Jeffrey Dahmer dominate conversations, their stories retold in books, documentaries, and podcasts. Yet, history’s spotlight often ignores equally monstrous figures from earlier eras, whose brutality rivaled the most infamous killers. These six underrated serial killers operated in the shadows of the early 20th century, claiming dozens of lives through cunning deception, savage violence, and unimaginable cruelty. Their cases, though shocking in their time, have faded from public memory, overshadowed by modern sensationalism.
What unites them is not just their body counts but the eerie normalcy they projected—farmers, handymen, lovers—while harboring lethal secrets. From a Norwegian immigrant luring suitors to their doom in rural America to a German butcher peddling human flesh, these killers exploited societal blind spots. This article delves into their lives, crimes, and downfalls, honoring the victims whose stories demand remembrance.
By examining these forgotten predators, we uncover patterns in human depravity that transcend time: the lure of greed, the thrill of power, and the failure of justice to act swiftly. Their legacies serve as stark reminders that evil wears many faces, often overlooked until too late.
1. Belle Gunness: The Black Widow of La Porte
Bella Sorenson Gunness arrived in the United States from Norway in 1881, seeking the American dream. Settling in Indiana, she married, opened a candy store, and bore children. But tragedy struck repeatedly—infants died mysteriously, fires destroyed her businesses. By 1900, widowed and insured, Gunness had transformed into a calculating killer, preying on lonely men through matrimonial ads.
Early Life and Motive
Born Brynhild Paulsdatter Størseth in 1859, Gunness endured a harsh upbringing on a impoverished farm. Immigration records show her arriving alone, determined to build wealth. Her first husband, Mads Sorenson, died of arsenic poisoning in 1900, netting her $8,000 in insurance. A second marriage to Peter Gunness ended when he was killed by a “falling meat grinder”—another payout. Analysts believe greed fueled her, as she amassed over $250,000 (millions today) from victims.
The Crimes
From her La Porte farm, Gunness advertised for suitors with property, promising love and stability. Dozens answered. Bodies unearthed in 1908 revealed her horrors: her three children, decapitated suitors, and dismembered remains stuffed in hog pens or under soft soap vats. Estimates range from 14 to 40 victims, mostly Scandinavian immigrants trusting her maternal facade. One survivor recounted her chilling calm as she counted his money before attempting to bash his head.
Investigation and Disappearance
Suspicion arose when suitor Andrew Helgelien vanished. His brother Asle dug up the farm, uncovering mass graves. A fire destroyed the farmhouse, leaving a headless female corpse presumed to be Gunness. Dental records didn’t match, and witnesses reported seeing her flee. She vanished, her fate unknown—rumors persist of sightings in California or Chicago. No arrests followed, leaving her crimes unsolved in full.
2. Earle Nelson: The Strangler Known as the Gorilla Man
In the mid-1920s, a hulking figure terrorized North America, strangling landladies and brides-to-be. Earle Leonard Nelson, dubbed the “Gorilla Man” for his ape-like strength, left a trail of 22 confirmed murders across the U.S. and Canada, his depravity marked by post-mortem assaults.
Troubled Beginnings
Born in 1897 in San Francisco, Nelson lost his mother young and was raised by a domineering grandmother versed in Christian Science. Head injuries from falls led to erratic behavior; by 10, he attempted strangulations. Institutionalized multiple times for burglary and assaults, he escaped repeatedly, honing his predatory skills.
Across the Continent
Nelson’s spree began in 1926 in San Francisco, evolving to full-time killing. He rented rooms from widows, strangled them during inspections, hid bodies under beds, and rifled possessions. Victims like Clara Newman and Laura Beal were violated postmortem. Crossing into Canada, he married a 14-year-old girl bigamously before killing her mother. His signature: livor mortis ignored as he moved corpses. Police linked him via fingerprints and witness sketches of his distinctive gait.
Trial and Execution
Captured in Manitoba after a survivor’s description, Nelson confessed nonchalantly, claiming demonic voices. Tried in Winnipeg, his defense cited insanity from head trauma. Jurors rejected it; he hanged in 1928 at age 30. Victims’ families found scant closure, their losses buried in yellowed newspapers.
3. Henri Désiré Landru: France’s Bluebeard
During World War I, while men fought, Henri Landru seduced women left vulnerable, murdering at least 11 in his Villa Ermitage. Known as “Bluebeard” after the folktale killer, he dismantled and incinerated bodies in his stove, evading detection through meticulous fraud.
Background of Deceit
Born 1869 in Paris, Landru was a mechanic turned swindler, bankrupting families via bad investments. Draft-dodging by feigning illness, he wooed widows via ads, promising security. His wife remained oblivious as he amassed victims’ fortunes.
The Villa of Horrors
From 1915-1919, Landru lured women like Madame Cuchet and her son. He documented each meticulously—lists of names, jewelry inventories found post-arrest. Remains included charred bones, teeth, and medical devices unearthed in Gambais. One jawbone matched victim Andrée Babelay. He claimed they “went to Paris,” forging letters.
Justice Delayed
A victim’s brother alerted police in 1919. Landru’s calm during searches—burning evidence mid-raid—delayed proof. Tried in 1921, his quips (“The bones? Chicken!”) failed. Convicted, he guillotined in 1922. Families reclaimed scant belongings, haunted by his evasion.
4. Fritz Haarmann: The Butcher of Hanover
In post-WWI Germany, Fritz Haarmann and accomplice Hans Grans killed at least 24 young men, butchering them for profit. Haarmann bit victims’ throats during assaults, earning “Werewolf of Hanover.”
Path to Atrocity
Born 1879, Haarmann was bisexual, arrested young for child molestation. Released into poverty after WWI, he posed as a detective, luring runaways from Hanover station.
Horrific Trade
1918-1924, Haarmann strangled or cut throats, dismembered in his apartment, sold meat as pork at markets. Clothes peddled secondhand. Skulls found in the Leine River linked cases. Grans profited knowingly. Haarmann confessed to 27 murders, describing orgiastic killings.
End of the Trade
A tip from a tenant’s observation led to his 1924 arrest. Evidence: bloodstained tools, victim effects. Tried with Grans, Haarmann guillotined December 1924; Grans shot in 1925. Hanover reeled; public outrage sparked cannibalism fears.
5. Peter Kürten: The Vampire of Düsseldorf
Peter Kürten’s 1930 reign of terror in Düsseldorf blended stabbing, strangling, and blood-drinking, killing nine in months. His sexual sadism and arson marked him as a proto-profiling case study.
Formative Cruelty
Born 1883 in poverty, abused by his father, Kürten tortured animals young. Jailed for crimes, he escalated post-WWI unemployment.
Terror Campaign
1929-1930: Hammerings, slashings of women and girls. He drank blood from wounds, revisited scenes. Maria Klawonn survived, describing his calm. Ten attacks, nine fatal.
Capture and Confessions
A survivor identified him; he confessed gleefully, detailing orgasms from killings. Insanity plea failed at 1931 trial; guillotined July 1931. His case influenced early criminal psychology.
6. Carl Panzram: The Ultimate Outlaw
Carl Panzram confessed to 21 murders, 1,000 rapes, and arsons across America and abroad, a rage-fueled rampage ending at Leavenworth.
Life of Violence
Born 1891 Minnesota, beaten in reformatories, he hated society. Escaped chains, served merchant ships raping boys.
Global Spree
1920s: Strangled six in New Haven, fed boys to alligators in Africa (claimed). Killed guards, robbed banks. Diary detailed psychopathy.
Final Reckoning
Arrested 1928, befriended warden; wrote autobiography. Hanged 1930, defiant: “Hurry it up!” His manuscript exposed institutional failures.
Conclusion
These six killers—Gunness, Nelson, Landru, Haarmann, Kürten, Panzram—faded as media evolved, yet their savagery underscores timeless truths: predators thrive on trust, war’s chaos, and indifference. Victims, often marginalized, remind us to amplify forgotten voices. History may forget, but vigilance endures. Studying them prevents repetition, honoring the lost with knowledge.
