In parallel with his main professional occupation as a researcher and leader of an institution, Paul Scherrer also served in various institutions and committees involved in the dissemination of nuclear energy in Switzerland: the Swiss Federal Council appointed him to the post of President of the Swiss Study Commission on Atomic Energy in 1946, and President of the Swiss Commission for Atomic Sciences in 1958. In addition, he also took part in establishing CERN near Geneva in 1954, and in setting up Reaktor AG to study the construction and operation of nuclear fission facilities one year later, in Würenlingen.
