About Shin'ichirō Tomonaga

Shinichiro Tomonaga, usually cited as Sin-Itiro Tomonaga in English, was a Japanese physicist. He shared the 1965 Nobel Prize in Physics with Richard Feynman and Julian Schwinger "for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles". With this term, the theory gave finite results; thus Tomonaga discovered the renormalization method independently of Julian Schwinger and calculated physical quantities such as the Lamb shift at the same time. In 1965, he was awarded the Nobel Prize in Physics, with Julian Schwinger and Richard P. He was awarded the Order of Culture in 1952, and the Grand Cordon of the Order of the Rising Sun in 1976.
