Michiyo Tsujimura – Past Life and Family
Tea scientist Michiyo Tsujimurawas born in 1888 in Okegawa, Japan. However, it was not recorded whether she got married. Or had any child during her career.
Michiyo became the first woman to get a PhD in chemistry and Agriculture. Then, she did extensive research on the benefits of green tea.
However, becoming a female scientist was not an easy feat. Michiyo’s career started as an unpaid laboratory assistant at Hokkaido Imperial University even though the university did not accept female students.
She moved to a medical Chemistry laboratory at Tokyo Imperial University in 1922. But her work and laboratory were now decimated by the tragic Great Kanto Earthquake in 1923. Here, more than 100,000 people were also killed.
Then, scientist and vitamin pioneer Umetaro Suzuki took Tsujimura under the swing. Further, she moved to a laboratory at the Riken Scientific Research Institute.
Moreover, with her colleague Seitaro, Miura found vitamin B1. Along with high levels of Vitamin C in green tea. Michiyo’s paper, “Vitamin C in Green Tea”, made green tea popular in North America. Also, exports increased from Asia to the US.
Michiyo Tsujimura – Achievement
Michiyo Tsujimura is a Japanese agriculture scientist, biochemist and, green tea researcher. Further, awarded the Japan Prize for Agriculture Science in 1956. And later she became a professor emeritus in 1963.
She was the first female to receive a doctoral degree in agriculture in Japan.
Early, she began her research at Hokkaido Imperial University as a laboratory assistant. Here, she worked at the food nutritional laboratory. At the university’s agriculture chemistry department.
However, she worked without pay because they don’t accept females into the University.
Later, she researched green tea in the agricultural chemistry field. Further, she became the first female professor emeritus. Then, it was conferred the order of the precious Crown of 4th class in 1968.
Michiyo Tsujimura – Education
Michiyo Tsujimura started her education at the Tokyo Prefecture Women’s Normal School. Moreover, her division of biochemical science at Tokyo Women’s Higher Normal School.
Then, she graduated in 1909 under the tutelage of a biologist, Kono Yaui. Here, she gathered her inspiration to go into scientific research.
In 1913, she graduated and started her career as a school teacher. At Yokohama High School for women in Kanagawa Prefecture.
Further, in 1920, she taught for 3 years at Saitama Women’s Normal School. Then, she joined Hokkaido Imperial University as a lab assistant.
Here, she worked in an unpaid position at the Food Nutrition Laboratory. Because the university did not accept female students at that time.
Michiyo Tsujimura – Career
In 1922, she worked at the Medical College of Tokyo Imperial University. Here, she focused her research on the “Nutrition of Silkworm”.
In 1923, the Tokyo Imperial University was destroyed by the Great Kanto Earthquake.
Further, she got transferred to a new Research Institute in Japan, RIKEN. Here, she worked as a research student instead of an unpaid staff member.
As a Doctor of Agriculture, she worked in the laboratory of Umetaro Suzuki. Here, she researches nutritional chemistry.
Further in 1923, Michiyo and her colleagues discovered Vitamin C in green tea. Later, they published an article in the journal Bioscience, Biotechnology. And Biochemistry title “On Vitamin C in Green Tea”.
Michiyo Tsujimura Green Tea Research
Tsujimura’s green tea research began in 1924 with her colleagues. Then, she and Seitaro Miura discovered Vitamin C in green tea.
Afterwards, they published an article in the general Bioscience, Biotechnology. And Biochemistry title “On Vitamin C in Green Tea”.
After the publication, they extract Vitamin C from green tea. Then, they help to increase the green tea export to North America.
While still researching green tea she also isolated another constituent, called “Flavonoid Catchein”.
In 1932, they extracted Tannin from green tea in crystal form. Then, this research earned her a doctorate in Agriculture. With a thesis titled “On The Chemical Component of Green Tea” at Tokyo Imperial University.
In 1942, she was promoted to work in RIKEN as a junior researcher. Further, she became a professor at Ochanomizu University in 1949.
Michiyo Tsujimura Google Doodle
Tsujimura’s next birthday is reportedly the 134th posthumous birthday. After she died at 88 years old. Google Doodle showed Michiyo extracted work from her green tea research. On her 133rd posthumous birthday.
Michiyo conducted various research. But she was actually known for her green tea research. Along with the discovery of Vitamin C from green tea.
However, Google used some of her research components. Such as tea shrubs, and a cup of green tea. Also, a flask and a notepad. So, they can form her 133rd Google letter in the Google Doodle.
Michiyo Tsujimura – Death Cause
Michiyo’s death isn’t documented in any online journal or archive.
However, the Japanese researcher died at the age of 81 in Toyohashi, Achievement, Japan.
Conclusion
Michiyo Tsujimura, born on September 17, 1888, in Okegawa, Japan. She graduated from Yokohama High School for Women in Kanagawa Prefecture. Further, she received the Japan Prize for Agriculture Science. She also received the 4th class precious Crown order in 1968. Lastly, she passed away in Toyohashi on 1 June 1969. At nearly the age of 81.
