An illiterate American orphan girl who was instrumental in
arousing lively interest in Spiritualism in Ohio soon after the
phenomenon of the Rochester Rappings. Mrs. Kellogg of
Massillon, in whose house Warner performed domestic services,
discovered that raps were produced in the girls presence.
Soon she was able to move into a trance state, and the uneducated
girl, who at eighteen could only read printed
characters, wrote with both hands at the same time on different
subjects, while a third communication was spelled out by raps.
Reports of the séances began to be widely circulated. Abel
Underhill, a physician, took the girl into his family for medical
treatment and wrote her history. The occurrences at St. Timothys
Church on Christmas Eve, 1851, put her in the limelight.
Supposedly, unusually powerful raps resounded in the church
in her presence and attracted the attention of the whole assembly.
The minister asked that those knockings might cease. Instead,
they increased in vehemence.
Warner was arrested on a charge of disturbing a religious
meeting and brought before a public tribunal. The trial commenced
on December 27 and lasted for three days. As not a
single witness could be found who could swear that they perceived
the slightest movement in the accused party; on the contrary,
when closely examined, those who professed to have
scrutinized the action of the spirit rapper narrowly were compelled
to admit that they could not detect the least perceptible
motion, even of her dress, at the times when the knocks were
most numerous and emphatic, the defendant was discharged.
Following the acquittal, Underhill announced an investigation
by a selected committee, under stringent test conditions,
of the mediums physical and mental phenomena. Four séances
were held. The committee believed the phenomena wholly unaccountable
and genuine evidences of an occult and intelligent
force outside the medium.
