  We present the Theorem Prover Museum, and initiative to conserve -- and make
publicly available -- the sources and source-related artefacts of automated
reasoning systems. Theorem provers have been at the forefront of Artificial
Intelligence, stretching the limits of computation, and incubating many
innovations we take for granted today. Without the systems themselves as
preserved cultural artefacts, future historians will have difficulties to study
the history of science and engineering in our discipline.
