Inventors
Umetarō Suzuki
Umetaro Suzuki (1874-1943) was a Japanese agricultural chemist who in 1910 became the first person in the world to extract the anti-beriberi factor from rice bran, which he named Oryzanin — later identified as vitamin B1 (thiamine). He experimentally proved that beriberi was caused by a nutritional deficiency, making him a pioneer in vitamin research. As a professor at Tokyo Imperial University and a founding member of RIKEN, he helped build the foundation of Japanese chemical research.
