Sin-Itiro Tomonaga
31 March 1906 – 8 July 1979
Sin-Itiro Tomonaga (1906-1979) was a Japanese theoretical physicist who developed a covariant formulation of quantum electrodynamics and the method of renormalization. He shared the 1965 Nobel Prize in Physics with Julian Schwinger and Richard Feynman for fundamental work in quantum electrodynamics. He later served as president of the Tokyo University of Education and was a prominent advocate for the peaceful use of science.
