Umetaro Suzuki (鈴木 梅太郎 Suzuki Umetarō?) (April 7, 1874 – September 20, 1943) was a Japanese scientist, born in Shizuoka Prefecture. He was one of the students of famed German Chemist, Emil Fisher. When researching the effects of rice bran in curing patients of beriberi, he discovered an active fraction in 1910 and received patent rights to aberic acid (later orizanin), which in 1935 after the correct composition became known as thiamine. His research was among the earliest of modern vitamin research. He was a professor of Agricultural chemistry at the University of Tokyo.
