Paul Scherrer (1890 - 1969) Studied physics and mathematics at the Swiss Federal Institute of Technology (ETH) Zurich, in Königsberg and Göttingen in Germany 1920: Director of The Institute of Physics at the ETH Zurich. Became well-known for the clarity of his lectures Researched X-ray scattering on crystals, liquids and gases. Later research work was in nuclear physics 1946: President of the Swiss Study Commission on Atomic Energy Involved in the founding of CERN
