In the summer of 1971, after a 50 year career in cancer research, Riojun Kinosita, M.D., Ph.D., was honored with a retirement celebration hosted by the medical center staff at City of Hope. At the time of his retirement, Kinosita had spent 20 years working at City of Hope and was the chair emeritus of Experimental Pathology.
Kinosita, born in 1893, made many contributions to the field of cancer research from the 1920s to the late 1970s. He studied at both the Imperial University Medical School in Tokyo and at Cambridge, Freiburg im Breisgau in Germany, and London. He also helped to “cultivate the next generation of leaders in Japanese cancer research” as a professor of pathology at Imperial University in first Hokkaido and then Osaka. (Ohno, 1978, 871).
Some of the research accomplishments that Kinosita achieved throughout his career included findings about carcinogens. He “demonstrated [in 1934] that a chemical called butter yellow, used to color food, induced cancer of the liver.” Kinosita also “reported, [in 1936 at the Japanese Pathology Society], that other substances, including tobacco tar, could cause cancer.” (Scope, 1971, 5). Furthermore, Kinosita headed the City of Hope Cancer Research Institute that was dedicated on July 18, 1952. (The Torch of Hope, 1952, 1). The institute contained “laboratories for experimental pathology, histology, biochemistry, microbiology, tissue culture, as well as rooms for animal breeding, medical illustrations, instruments, statistics, a library, and a conference room.” (Ibid).
