Shoichi Sakata

Shoichi Sakata (坂田 昌一, Sakata Shōichi, 18 January 1911, near Hiroshima – 16 October 1970) was a Japanese academic and physicist who was internationally known for theoretical work on the structure of the atom. He proposed the Sakata model, which was an early precursor to the quark model.
After the end of World War II, he joined other physicists in campaigning for the peaceful uses of atomic energy.
Career
Between 1929 and 1933 Sakata studied physics in Tokyo under Yoshio Nishina and later at the Kyoto Imperial University under Hideki Yukawa, the first Japanese Nobel laureate. He first met Yukawa at Rikagaku Kenkyūsho in Ōsaka, a private research foundation started by Yukawa. Here he worked with him from 1937 on meson theory and in 1939 accompanied him to Kyoto University where Yukawa was a lecturer. Sakata was appointed professor at Nagoya University in 1942 and remained there until his death.
