On Friday, Google honored Japanese chemist Michiyo Tsujimura for his work on green tea, with a Doodle honoring him.
Today’s Google Doodle says it all. Michiyo Tsujimura was Japan’s first female doctor of agriculture thanks to her trailblazing work.
Doodle displays Tsujimura extracting the chemical components of green tea
Michiyo Tsujimura’s 133rd birthday is commemorated on Google’s homepage, which displays her investigating and extracting the chemical components of green tea.
The letters of ‘Google’ were created using a tea shrub, a cup of green tea, a pen, a flask, and a notepad, among other research materials.
Who was Michiyo Tsujimura?
Michiyo Tsujimura, recognized for her revolutionary research into the nutritional advantages of green tea, was born in 1888 in Okegawa, Saitama Prefecture, Japan.
While still in school, Tsujimura was encouraged to pursue a career in scientific research.
Tsujimura spent her early career teaching science, according to the Google site.
She began studying the nutritional qualities of Japanese silkworms at Hokkaido Imperial University in 1920, pursuing her aim of becoming a scientific researcher.
Tsujimura’s journey with Green Tea; findings in her thesis
Tsujimura transferred to Tokyo Imperial University a few years later and began studying the biochemistry of green tea with Dr. Umetaro Suzuki, the man responsible for the discovery of vitamin B1.
Green tea contains considerable levels of vitamin C, which was the first of several undiscovered chemical components in green tea awaiting examination under the microscope.
Tsujimura discovered catechin, a bitter component of tea, in 1929. She then isolated tannin, an even more bitter chemical, the next year. When she graduated as Japan’s first woman doctor of agriculture in 1932, she used these discoveries to write her Ph.D. thesis, “On the Chemical Components of Green Tea.”
Tsujimura became an assistant professor at Ochanomizu University after finishing her research work. Dr. Tsujimura created history as the first Dean of the Faculty of Home Economics at Tokyo Women’s High Normal School in 1950, in addition to her research accomplishments.
Today, at her birthplace of Okegawa City, a stone plaque honoring Dr.achievements Tsujimura can be found.
In 1956, Tsujimura received the Japan Prize of Agricultural Science for her work on green tea. She received the Order of the Precious Crown of the Fourth Class in 1968.
Michiyo Tsujimura died on June 1, 1969, when she was 80 years old.
