Biography
Fubini was born in Turin, from where he fled in 1938 as a politically persecuted Jew into Switzerland. Starting from 1945 he attended the Lycée in Turin, where he studied physics and in 1950 graduated "cum laude." Afterwards he was an assistant in Turin. From 1954 to 1957 he was in the USA and from 1958 to 1967 at CERNCERN
