NEW DELHI: Google on Friday paid tribute to Japanese educator and biochemist Michiyo Tsujimura's 133 birthday with a doodle.
The Google homepage shows her studying and extracting the chemical components of green tea.
Michiyo Tsujimura, born in 1888 in 1888 in Okegawa, Saitama Prefecture in Japan, is known for her groundbreaking research into the nutritional benefits of green tea.
As per the Google's blog, Tsujimura spent her early career teaching science. In 1920, she chased her dream of becoming a scientific researcher at Hokkaido Imperial University where she began to analyze the nutritional properties of Japanese silkworms.
A few years later, Tsujimura transferred to Tokyo Imperial University and began researching the biochemistry of green tea alongside Dr. Umetaro Suzuki, famed for his discovery of vitamin B1. Their joint research revealed that green tea contained significant amounts of vitamin C—the first of many yet unknown molecular compounds in green tea that awaited under the microscope.
In 1929, Tsujimura isolated catechin — a bitter ingredient of tea. Then, the next year she isolated tannin, an even more bitter compound. These findings formed the foundation for her doctoral thesis, "On the Chemical Components of Green Tea" when she graduated as Japan’s first woman doctor of agriculture in 1932.
Outside of her research, Dr. Tsujimura also made history as an educator when she became the first Dean of the Faculty of Home Economics at Tokyo Women’s Higher Normal School in 1950. Today, a stone memorial in honor of Dr.Tsujimura’s achievements can be found in her birthplace of Okegawa City.
