Victorian séance luminosity: How occult spectacle masked industrial-era chemical exposure and gendered exploitation

The 1857 séances occurred during a period of rapid industrialization, when phosphorus poisoning was rampant among female matchstick workers in Europe and the U.S. (e.g., the 'phosphorus necrosis' epidemic of the 1870s). Leah Brown’s symptoms align with chronic phosphorus exposure, which was also used in early medical treatments and photographic development—linking her case to broader systemic exploitation of women’s labor and bodies in emerging scientific and industrial sectors.
Leah Brown’s séance was not an isolated anomaly but a microcosm of the 19th century’s intersecting crises: the industrial exploitation of women’s labor, the colonial erasure of Indigenous and Afro-diasporic spiritual practices, and the dangerous fusion of science and spectacle.
Her luminous hands—both a product of chemical exposure and a spiritual manifestation—reveal how marginalized bodies became sites of experimentation, where the boundaries between fraud, resistance, and systemic harm were deliberately blurred. The trickster energy of her story lies in its ability to expose these contradictions: the séance was both a tool of exploitation and a form of resistance, a scientific curiosity and a spiritual act. By centering Indigenous knowledge, historical parallels, and marginalized voices, we can reframe Brown’s experience as a warning—one that resonates with modern struggles over workplace safety, epistemic justice, and the commodification of the body. The solution lies not in dismissing her account as mere 'chemical trickery' but in acknowledging it as a site of systemic critique, where the past’s shadows illuminate the present’s injustices.
