TL;DR
While most infamous serial killers are men, the Smithsonian notes that in the 1800s, women frequently used arsenic to commit serial murders. This period is known as the ‘Golden Age of Arsenic.’ The development sheds light on gender and crime in history.
The Smithsonian states that in the 1800s, many women were involved in serial poisoning cases, often using arsenic, which led to the era being called the ‘Golden Age of Arsenic.’ This highlights a historical pattern of female serial killers that contrasts with the predominantly male profile of such criminals today.
According to the Smithsonian, during the 19th century, numerous women were arrested for serial poisoning, primarily using arsenic. This period saw a notable rise in female serial killers, earning it the nickname ‘Golden Age of Arsenic.’ The use of poison was often motivated by personal motives, including financial gain and revenge, and was facilitated by the accessibility of arsenic at the time. Historical records indicate that these cases were widely reported and caused significant public concern, leading to increased scrutiny of domestic and social environments where women had access to toxic substances.
Why It Matters
This development matters because it challenges the common perception that serial killers are predominantly men. It also offers insight into gender roles, societal expectations, and the types of crimes women committed historically. Understanding this history can inform contemporary discussions about gender and criminal behavior, as well as the evolution of forensic investigations and poison detection methods.

Background
Historically, the 1800s saw a rise in poisonings, often linked to women accused of serial murders. The era’s social and legal environment made poisoning a covert method of killing, with arsenic being a common choice due to its availability and difficulty to detect at the time. This period predates modern forensic science, which has since improved the detection of poisons and reduced the likelihood of undetected serial poisonings. The phenomenon has been documented in historical records and analyzed by researchers, including those at the Smithsonian, who highlight the gendered aspect of these crimes.
“The 1800s saw a significant number of women involved in serial poisoning cases, which earned that era the nickname ‘Golden Age of Arsenic.'”
— Smithsonian researcher
“Poisoning was often seen as a ‘female’ crime in the 19th century, partly because women had easier access to toxic substances and were socially permitted to handle domestic chemicals.”
— Historical criminologist

What Remains Unclear
It is not yet clear how many of these cases were accurately prosecuted or if many went undetected. The exact number of female serial poisoners in the 1800s remains uncertain due to limited record-keeping and the clandestine nature of poisonings at the time.

What’s Next
Researchers are expected to continue examining historical court records and forensic evidence to better quantify and understand the scope of female serial poisoners in the 19th century. Further studies may also explore societal factors that contributed to this phenomenon and how it influenced modern forensic practices.

Key Questions
Why were women more involved in poisonings during the 1800s?
Women had easier access to toxic substances like arsenic and were often involved in domestic settings, which facilitated poisoning. Social norms also allowed women to handle chemicals without suspicion.
How did authorities detect arsenic poisoning in the 1800s?
Detection methods were limited at the time, often relying on symptoms and rudimentary tests. Modern forensic techniques like chemical analysis were developed later, improving detection accuracy.
Are there known cases of female serial killers today?
While female serial killers are less common today, they do exist, often with different methods than those used in the 1800s. Modern profiling and forensic science have changed how such cases are investigated.
What impact did these poisonings have on society at the time?
The widespread cases of poisoning caused public panic and led to increased regulation of toxic substances, as well as reforms in criminal investigations.
