Who Was Michiyo Tsujimura, why google pays tribute with a doodle ?

I stumbled across a doodle in Google doodles. The doodle is of Michiyo Tsujimura, a Japanese woman born in 1888 and is famous for her research on green tea and what benefits does green tea provide.

Google released a doodle in honor of Japanese scientist Michiyo Tsujimura. Tsujimura is known for her contributions to a great invention of green tea and extraction of chemical components of green tea.

Michiyo Tsujimura, was a Japanese plant physiologist who researched green tea while studying abroad in Germany. She is best known for her discoveries of the connection between green tea and the catechin content of leaves, which led to better methods of drying tea leaves.

The Google Doodle pays tribute to her work with a vibrant animation that features Michiyo brewing green tea, surrounded by artfully drawn cup designs.

Perhaps you're enjoying your morning coffee right now? If so, it's worth noting that without Michiyo's dedication to science and engineering—and her insistence on testing new ideas on herself—your coffee would have been just another drink among many.

She went on to study plant physiology under Dr. Fujiwara at the Imperial College of Agriculture and Natural Resources in Tokyo, where she earned a degree in 1907.

After her graduation, she worked as an assistant at the Botanical Laboratory of the Imperial College of Agriculture and Natural Resources until 1914, where she researched new ways to dry tea leaves so that they could be sold year round.

In 1917, she moved to England to study a green tea called 'Autumn Tea', which was later named 'Green Tea' in her honor. And it was here that she succeeded in isolating and characterizing the active ingredients in green tea leaves. In 1928, Tsujimura returned to Japan and continued her research.

In 1930, Tsujimura managed to isolate a catechin from green tea leaves, which is now known as epigallocatechin-3-gallate (EGCG).

Michiyo was one of the greatest scientists. When she moved to Tokyo for her further research on green tea, she firstly came across a bitter ingredient of green tea which was catechin. Following her path, the very next year, she found a more bitter form of green tea which was tannin. She gave this thesis the name, "on the Chemical Components of Green Tea".

In 1932, she was the very first woman from Japan to complete her graduation in agriculture. Because of her huge contribution to the world, she also made history in Japan by becoming the first ever Dean of Faculty of Home Economics at Tokyo Women's Higher Normal School.

She was honoured with a memorial stone at her hometown, Okegawa City, Japan.
