Google Doodle: Dr. Saruhashi’s 98th Birthday
On March 22, 2018, Google honored Katsuko Saruhashi with a Google Doodles celebrating her life and legacy.
A young Katsuko Saruhashi sat in primary school watching raindrops slide down a window and wondered what made it rain. Her journey for answers led her to become the first woman to earn a doctorate in chemistry from the University of Tokyo in 1957.
Saruhashi is renowned for her groundbreaking research as a geochemist. She was the first to accurately measure the concentration of carbonic acid in water based on temperature, pH Level, and chlorinity. Named ‘Saruhashi’s Table’ after her, this methodology has proved invaluable to oceanographers everywhere. She also developed a technique to trace the travel of radioactive fallout across the oceans that led to restricting oceanic nuclear experimentation in 1963.
During a career spanning 35 years, Saruhashi became the first woman elected to the Science Council of Japan in 1980, and the first woman honored with the Miyake Prize for geochemistry in 1985 - among many other awards. 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.
Today on her 98th birthday, we pay tribute to Dr. Katsuko Saruhashi for her incredible contributions to science, and for inspiring young scientists everywhere to succeed.
