The Science Museum and the imaginarium of steam, 1725–1840.

The Science Museum has in its East Hall one of the finest collections of steam engines anywhere. The collection has traditionally been interpreted in formal taxonomical terms. However, as the display scheme has become physically fragmented, and the museum's relationship with its visitors has been assessed in new ways, so new approaches to interpreting the collection have been sought. The primary and secondary source review underpinning development of a revised gallery scheme for the East Hall suggested the existence of an 'imaginarium of steam', a body of historic material illustrating how the steam engine exerted an imaginative hold on those who built, worked with, and observed it. The steam engine was as much a symbolic and imaginative machine as it was a tangible one. This is reflected in a rich range of sources, stretching far beyond the technical sources so traditionally and closely identified with the engine. This paper will outline some of these primary sources with particular reference to the museum's collection and other appropriate material culture, and attempt to identify some of their shared characteristics, which together form the imaginarium.
