Origins of Halloween
The Victorian Séance
In 1848, two sisters in Hydesville, New York, claimed that a spirit was answering them in knocks. Within a few years, darkened parlors across America and Britain were filled with clasped hands, tilting tables and voices in the dark. This guide traces the séance from its origins to its debunkers, and why it still haunts Halloween.
The short answer
The Victorian séance grew from the Spiritualist movement, which began in 1848 when Kate and Margaret Fox reported spirit rappings in Hydesville, New York. Spiritualism spread quickly through the United States and Britain. Mediums held séances featuring table-turning, rapping, trance speech and later 'materializations'. Many famous mediums were exposed as frauds, and Margaret Fox herself confessed in 1888, though she later recanted.
Key points
- Modern Spiritualism is usually dated to the Fox sisters' rappings in 1848.
- Table-turning became a parlor craze in the 1850s on both sides of the Atlantic.
- Grief, particularly after the American Civil War, drew many people to séances.
- Investigators, scientists and stage magicians exposed numerous tricks.
- Our Midnight Séance game and parlor stories are fiction inspired by this era.

Hydesville and the Spiritualist Movement
Spiritualism taught that the dead could communicate with the living, often through a gifted person called a medium.
The Fox Sisters
Knocks in a farmhouse became an international movement.

What happened
The sisters reported knocks that answered their questions.

Inside a Victorian Séance
A séance was often a domestic event: a dim room, a round table and a small circle of sitters.
What Sitters Expected
Phenomena grew more theatrical as the century went on.
Common phenomena
- Rappings and table-tilting
- Spirit writing on slates
- Trumpets and tambourines in the dark
- 'Materialized' spirit forms
How investigators explained them
Sitters joined hands, which also meant no one could check the medium's movements.
Researchers found hidden accomplices, concealed props and practiced sleight of hand.
Stage magicians, and later Harry Houdini, demonstrated how such effects could be faked.
Belief persisted anyway; for many, the comfort mattered more than proof.
