Google honors green tea researcher Michio Tsujimura with a new doodle

September 17 (WNN) — Google is celebrating Michio Tsujimura, an educator and biochemist who researched the nutritional benefits of green tea, with a new doodle.

Google’s homepage on Friday features artwork by Tsujimura studying green tea inside a lab. The doodle was made to commemorate his 133rd birthday.

Tsujimura was born on this day in 1888 in Okegawa, Saitama Prefecture, Japan. He studied Japanese silkworms at Hokkaido Imperial University in 1920 before transferring to Tokyo Imperial University to study the biochemistry of green tea.

Tsujimura worked with Dr. Umetaro Suzuki, who first discovered vitamin B1. Both found that green tea contained high amounts of vitamin C.

Tsujimura isolated catechins, a bitter component of tea, in 1929 and then later isolated the more bitter compound tannins. The findings helped him create his doctoral thesis titled “On the chemical constituents of green tea”.

The researcher graduated as Japan’s first female doctor of agriculture in 1932 and became the first dean of the Faculty of Home Economics at Tokyo Women’s Higher Normal School in 1950.

A stone monument in honor of Tsujimura is located in the city of Okegawa.
