Born Mar. 31, 1906, in Kyoto. Japanese theoretical physicist.
Tomonaga graduated from Kyoto University in 1929. In 1932 he became a staff member of the Institute of Physical and Chemical Research, where he worked under Y. Nishina. From 1937 to 1939 he studied under W. Heisenberg in Leipzig. He became a professor at the Tokyo University of Education in 1941.
Tomonaga’s principal works deal with magnetism, the theory of neutrons, and quantum field theory. His relativistically invariant formulation of the quantum theory of wave fields stimulated the development of a renormalization method.
Tomonaga received a Nobel Prize in 1965. He became a foreign member of the Academy of Sciences of the USSR in 1971.
