• These multi-faceted lantern shows, combining image and
sound were continued throughout the 19th century.
Subject matter varied, from educational lectures, to
advertising, comic slides and illuminated narratives. The
height of this type of entertainment was probably reached
with the shows exhibited at the Royal Polytechnic Institute
in London (1838-1882) which employed a number of
people behind the scenes in providing sound effects for the
shows.
The phantasmagoria shows, which had their heyday in the
late 18th and early part of the 19th century, can probably be
credited with being the first all sensory entertainments. The
back bone of the shows was the secret projection and sudden
appearance in the darkened rooms of fast approaching
ghosts, which just as quickly receded. Live actors, sounds,
smells, sometimes even electric shocks were used to augment
the effect of the ghostly projections and create an all round
frightening experience.
