Katsuko Saruhashi Google doodle honors first woman elected to Science Council of Japan


Today’s Google doodle honors Katsuko Saruhashi on what would have been the geochemist’s 98th birthday.

Saruhashi was renowned in her field of geochemistry and spent much of her career advocating for the advancement of female scientists.

“She was deeply committed to inspiring young women to study science, and established the Saruhashi Prize in 1981, recognizing female scientists for distinguished research in natural sciences,” writes Google Doodle on its Google Doodle Blog.

According to Google, Saruhashi was the first woman to earn a doctorate in chemistry from the University of Tokyo; the first woman named to the Science Council of Japan; and the first woman honored with the Miyake Prize for geochemistry.

Google says she was also the first scientist to accurately measure the concentration of carbonic acid in water, and her work led to the “Saruhashi’s Table” methodology which is now used by oceanographers worldwide. Her research on the impact of radioactive fallout on the world’s oceans resulted in restrictions around oceanic nuclear experiments.

The doodle leads to a search for “Katsuko Saruhashi” and is posted on Google’s US and Japan home pages, along with a number of its other international pages.

Google also included the following quote from Saruhashi in its blog post about the geochemist, an idea that still needs amplification today: “There are many women who have the ability to become great scientists. I would like to see the day when women can contribute to science & technology on an equal footing with men.”
