Introduction
In Episode 91 of MrBallen’s Medical Mysteries, host MrBallen delves into the chilling events surrounding the Mad Gasser of Mattoon, a series of mysterious gas attacks that gripped the small town of Mattoon, Illinois, in 1944. This episode uncovers how fear and anxiety during wartime can lead to mass hysteria, blurring the lines between reality and perception.
The First Attack: Aline Kearney’s Ordeal
The story begins on the evening of September 1, 1944, with Aline Kearney and her family settling in for the night in their peaceful Mattoon home. Aline, anxious about her husband Bert’s late-night taxi shifts amidst wartime fears, seeks comfort in the company of her sister Martha and nephew Roger.
At approximately [02:15], Aline experiences a sickeningly sweet odor filling her bedroom, leading to sudden paralysis in her legs. Despite her efforts to locate the source, nothing is apparent. Martha arrives just in time to shut the window, alleviating the immediate symptoms. Aline suspects a gas attack, but the police find no evidence, leaving the Kearney family unsettled.
Notable Quote:
"Stay with me, because this one's going to make you question everything you think you know about fear and how it can shape our reality."

Escalation of Fear: Burt Kearney’s Return
By midnight, Burt Kearney returns home after receiving a distressing call about a possible chemical attack. He spots a suspicious figure outside his window, described as a tall man in dark clothing. Burt chases the man into an alley but loses him, heightening the town’s fear.
[05:50] Burt contacts the police, who canvass the property but find nothing. Convinced of an impending threat, Burt evacuates his family to a relative’s home. The next day, the Mattoon Journal Gazette headlines the fear-stricken community, confirming Burt’s suspicions of an anesthetic prowler.
A Second Victim: Beulah Cordes’ Encounter
Five days later, Beulah Cordes becomes the next victim. After discovering a mysterious rag with a sweet scent on her front door, Beulah inadvertently inhales chloroform, leading to severe symptoms similar to Aline’s experience. Her husband Carl contacts the police, who find no immediate culprit but detain a suspect who quickly proves innocent.
Notable Quote:
"There was no mad gasser of Mattoon... just mass hysteria fueled by fear."
— Dr. Patrick McGrath [12:04]
The Investigation Deepens: Chief Cole’s Pursuit
Chief C.E. Cole of Mattoon Police faces mounting pressure as more residents report similar symptoms. Initial theories point to a chemical source, specifically the local Atlas Imperial Diesel Engine company, where the emissions match the reported odors. However, this hypothesis falls apart when it’s revealed that factory workers show no signs of poisoning.
[15:30] Undeterred, Chief Cole intensifies the search, including a thorough investigation of an abandoned house suspected to be the gasser’s hideout, but finds nothing conclusive. The community’s fear escalates, with neighbors arming themselves in desperation for protection.
Media’s Role and the Unraveling Investigation
The Mattoon Journal Gazette plays a pivotal role in amplifying the town’s fears, sometimes distorting facts and exacerbating the panic. The relentless media coverage fuels rumors and misconceptions, making it difficult for the police to identify the true cause of the symptoms.
[21:38] Chief Cole makes a public announcement attributing the illnesses to carbon tetrachloride emissions from the diesel plant. However, this explanation is swiftly debunked by experts, as the chemical should not affect those outside the factory environment.
Conclusion: Mass Psychogenic Illness Unveiled
On September 12, 1944, Chief Cole and the Commissioner of Public Health reveal the truth during a press conference. Medical tests confirm that the affected individuals show no signs of chemical poisoning. Instead, the symptoms are attributed to mass psychogenic illness, a phenomenon where communal fear and anxiety manifest as physical symptoms.
MrBallen concludes by highlighting how the Mad Gasser of Mattoon serves as a classic example of how fear, especially during turbulent times like World War II, can lead to widespread panic and unfounded fears of a lurking threat. The episode underscores the powerful impact of psychological stress and media influence on community health.
Final Insights:
"There are still some who believe that Aline and Beulah might have been genuine victims of a prowler who maybe attacked them with gas, who then skipped town once the media started reporting on his attacks. But there's no way to know for sure what truly happened."
