Katsuko Saruhashi
Katsuko Saruhashi (1920–2007) was a Japanese geochemist who developed tools to measure carbon dioxide levels in seawater.
She also highlighted the dangers of radioactive fallout and how far it can spread. In addition to her research on safety, she studied the peaceful uses of nuclear power.
Saruhashi was also committed to increasing the number and status of women scientists, especially in Japan. She founded both the Society of Japanese Women Scientists and the Saruhashi Prize, which is awarded annually to a female scientist who serves as a role model for younger women.
She was the first woman elected to the Science Council of Japan, earned a doctorate in chemistry from the University of Tokyo, and won the Miyake Prize for Geochemistry.
