Shinichiro Tomonaga was a Japanese physicist born in 1906. He received his degree from Kyoto University in 1929 and developed the theory of quantum electrodynamics, for which he received the 1965 Nobel Prize in Physics along with Julian Schwinger and Richard P. Feynman. Tomonaga's greatest achievement was his work developing the theory of quantum electrodynamics, which helped "rescue the theory without making any radical innovations."
