The 1913 Paterson Shirtwaist Factory Hysteria: An Early Documented Case of Mass Psychogenic Illness
On April 19, 1913, a rapid onset of fainting, nausea and trembling swept through workers at a Paterson, New Jersey, shirtwaist factory—one of the earliest well-documented factory mass psychogenic illness outbreaks in the United States, attributed at the time to 'contagion of fear' rather than identifiable toxic exposure.
The Paterson case fits features common to factory outbreaks of psychogenic illness in the late 19th and early 20th centuries. Industrial workplaces were noisy, hot, poorly ventilated and dominated by strict supervision—conditions that heightened fatigue and anxiety. Many workers were recent immigrants and young women who faced linguistic, economic and social pressures. In such settings, the sudden onset of non-specific neurological and gastrointestinal symptoms in one or a few individuals could be socially contagious: others, already primed by stress and suggestion, developed similar complaints. Medical accounts from the period emphasized the speed of spread, the predominance of subjective symptoms (fainting, nausea, headache, trembling) and the lack of physical findings or laboratory evidence pointing to a toxin or pathogen.
Newspapers and public officials of the time debated explanations. Some managers and lay commentators suspected malingering or organized disruption; some physicians cautioned against such judgments and pointed toward psychological contagion. The available primary sources—local press reports and municipal health records—documented the event without providing the kinds of systematic environmental testing or psychological interviews expected today. Later scholars place the Paterson episode in a broader pattern of worksite mass psychogenic events occurring in textile mills, factories and schools across industrializing societies, where stress, social cohesion and rapid information spread combined to produce identifiable clusters of symptoms.
Understanding this event through modern frameworks does not mean dismissing workers' suffering. Mass psychogenic illness produces real symptoms and disability even when no organic agent is found. Responses at the time ranged from temporary closures and removal of affected workers to calls for better ventilation and shorter hours—interventions that, whether or not directly connected to the cause, could alleviate stressors contributing to such outbreaks. The case also influenced public health thinking about how to investigate unexplained clusters of illness, highlighting the need for careful clinical assessment, environmental measurement and attention to social dynamics.
Historical documentation for the Paterson 1913 incident is limited: contemporaneous newspaper coverage and municipal notes form the primary record, and detailed clinical narratives or systematic epidemiologic data are generally absent. Some particulars—exact numbers affected, precise sequence of events and individual experiences—remain uncertain or unevenly reported. Nonetheless, the April 19, 1913, Paterson outbreak stands as a clearly recorded early example of mass psychogenic illness in a factory setting and as an instructive episode in the history of occupational health, public perception and medical interpretation of symptom clusters without identifiable organic causes.
