The Quantum Chemistry Program Exchange (QCPE) was an organization located at Indiana University Bloomington from 1963 to 2007. It was devoted to the distribution of computational chemistry software before electronic file transfer on the internet became a widely available method of software distribution. The QCPE was founded by Prof. Harrison Shull and was managed by Richard Counts for most of its existence. Financial support for the QCPE was originally provided by the Air Force Office of Scientific Research until 1969. Funding continued under an interim grant from the National Science Foundation in 1971, until it became financially self-sustaining in 1973.
