Marcello Conversi 70

Friends and colleagues of Marcello Conversi gathered in Rome on 3-4 November for a symposium 'Present Trends, Concepts and In­ struments of Particle Physics' to mark his 70th birthday. In 1946, Conversi, together with Ettore Pan- cini and Oreste Piccioni, showed that the cosmic ray 'mesotron' was the muon rather than the pion. Lat­ er his influential Pisa school pro­ duced famous Italian names in par­ ticle physics.
