Bruno Pontecorvo (August 22, 1913 - September 24, 1993) was an Italian-born atomic physicist, an early assistant of Enrico Fermi and then the author of numerous studies in high energy physics, especially on neutrinos. He became notorious, even outside the scientific community, because of his voluntary move to the USSR in 1950, where he continued his research on the decay of the muon and on neutrinos. The prestigious Pontecorvo Prize was instituted in his memory in 1995.
