Dagmar Overbye was a Danish child-minder convicted of killing infants entrusted to her care, in a case so disturbing that it helped transform Denmark's childcare and adoption laws. This account avoids graphic detail out of respect for the victims.
Operating in an era when desperate mothers paid 'baby farmers' to take in children they could not raise, Overbye exploited that grim system over a period of years before she was finally stopped.

Key Facts at a Glance
Full name: Dagmar Johanne Amalie Overbye
Born: 1887, Denmark
Setting: Copenhagen
Active: Roughly 1913-1920
Victims: Convicted of killing nine infants; suspected of many more
Outcome: Death sentence commuted to life imprisonment; died in 1929
The World of Baby Farming
In early twentieth-century Denmark, unmarried mothers and struggling families sometimes paid women to take in infants, either to raise or to arrange for adoption. This largely unregulated system created opportunities for abuse.
Overbye operated within this world, accepting payments to care for children whose mothers had few other options and little ability to check on what happened next.
A Hidden Toll
Over a period of years, a large number of infants placed with Overbye died or vanished. Because the children were often handed over in secrecy and shame, their fates went unquestioned.
The lack of oversight meant that the deaths did not trigger alarm for a long time, allowing the toll to mount unnoticed by the authorities.
Discovery
The case came to light when a mother who had entrusted her child to Overbye grew suspicious and went to the police. The ensuing investigation uncovered evidence of multiple deaths.
As detectives examined Overbye's history, the scale of the tragedy became clear, and she was arrested and charged.
Trial and Sentence
At her 1920 trial, Overbye was convicted of killing nine infants, though the true number was believed to be far higher. The case provoked national horror.
She was sentenced to death, but the sentence was commuted to life imprisonment. She remained incarcerated until her death in 1929.
Reforming the Law
The Overbye case exposed the dangers of the unregulated baby-farming system, and it spurred Denmark to reform its laws governing the care and adoption of children.
New oversight was introduced to protect vulnerable infants, making the case a turning point in Danish child-welfare history as well as a notorious crime.
A Tragedy That Drove Change
What sets the Overbye case apart is the way a horrifying series of crimes ultimately led to lasting protective reform. The deaths of the most defenceless victims forced society to confront a system that had failed them.
Her story endures in Denmark both as one of its darkest criminal episodes and as a catalyst for the safeguards that followed.
Baby Farming and Social Reform
The Overbye case was part of a wider European reckoning with baby farming, the practice by which women were paid to take in infants that desperate mothers could not keep. The same grim phenomenon produced notorious cases in Britain and elsewhere, exposing how little protection the most vulnerable children had.
In Denmark, the horror of Overbye's crimes helped drive reforms to regulate the care and adoption of infants and to provide better support for unmarried mothers. In this way a deeply tragic case became a turning point, prompting the kind of oversight that aimed to ensure such deaths could not recur unnoticed.
Protecting the Vulnerable
The deepest legacy of the Overbye case lies in the protections it helped bring about. The deaths of so many defenceless infants forced Denmark to confront the failures of an unregulated system and to act.
The reforms that followed aimed to ensure that children handed into the care of others could no longer simply vanish without question. In that sense, a profoundly tragic case became a force for lasting good in child welfare.
