“Michiyo Tsujimura” Net worth, Early Life, Career And Reason Behind Her Death!

Michiyo Tsujimura was a Japanese agricultural scientist and biochemist who studied green tea components. She was Japan’s first agriculture doctorate recipient.

Early Life

Tsujimura is born in Okegawa, Saitama Prefecture. In 1909, she graduated from Tokyo Prefecture Women’s Normal School and Tokyo Women’s Higher Normal School’s Division of Biochemical Science. The scientist Kono Yasui inspired Tsujimura to pursue the scientific inquiry.

In 1913, she graduated and taught at Yokohama High School for Women in Kanagawa. 1917, she taught in Saitama Women’s Normal School.

Career & Research

Tsujimura became a lab assistant at Hokkaido Imperial University in 1920. The university didn’t accept female students at the time, so Tsujimura worked unpaid at the Food Nutritional Laboratory of the Agricultural Chemistry Department. In 1922, she moved to the Medical Chemical Laboratory at Tokyo Imperial University’s Medical College to study silkworm feeding.

In October 1923, after the Great Kant Earthquake devastated her lab, she became a research student at RIKEN. In Umetaro Suzuki’s lab, she researched nutritional chemistry. In 1924, Tsujimura and Seitaro Miura found vitamin C in green tea and published “On Vitamin C in Green Tea” in Bioscience, Biotechnology, and Biochemistry. The discovery increased green tea shipments to North America.

In 1929, Tsujimura isolated green tea catechin. She froze green tea tannin in 1930. “On the Chemical Components of Green Tea” earned her a doctorate in agriculture from Tokyo Imperial University in 1932, making her the first woman in Japan to do so. In 1934, she isolated gallocatechin from green tea and patented a method for obtaining vitamin C crystals from plants.

In 1942, she became a junior researcher at RIKEN and a researcher in 1947. In 1949, she became a professor at Ochanomizu University. She taught at Tokyo Women’s Higher Normal School in 1950 and was its first dean of home economics.

Retirement & legacy

Professor Tsujimura withdrew from Ochanomizu University in 1955 but kept teaching part-time until 1961. She taught at Tokyo’s Jissen Women’s University from 1955 to 1963. She won the 1956 Japan Prize of Agricultural Science for her study on green tea and the 1968 Order of the Precious Crown of the Fourth Class.

Net worth

Michiyo has a huge net worth. Her income and earnings are not disclosed. But Tsujimura had made a lot of money in her work. She was a biochemist and agronomist. She gained the most from her various jobs.

Tea

Tsujimura studied green tea biochemistry with Dr. Umetaro Suzuki, who discovered vitamin B1. Green tea contains vitamin C, the first of many undiscovered chemical components. She isolated catechin in 1929. The next year, she isolated even bitterer tannin.

Reason Behind her death

His death occurred at the age of 80 and occurred in Toyohashi (Aichi prefecture), Japan on June 1, 1969. A monument honors her and all of her accomplishments. On September 17th, 2021, Google will commemorate the 133rd birthday of Japanese chemist Michiyo Tsujimura, who is well known for her extensive study of green tea.
