Kazimierz Funk[1] [kaˈʑimiɛʐ ˈfunk] (February 23, 1884 – November 19, 1967[2]), commonly anglicized as Casimir Funk, was a Polish biochemist,[3] generally credited with being amongst the first to formulate the concept of vitamins in 1912,[4] which he called vital amines or vitamines.[5] Umetaro Suzuki had succeeded in extracting a water-soluble complex of micronutrients from rice bran and named it aberic acid in 1910, but the German translation unlike the Japanese original failed to note it was a newly discovered nutrient.

Contribution to science

After reading an article by the Dutchman Christiaan Eijkman that indicated people eating brown rice were less vulnerable to beri-beri than those who ate only the fully milled product, he tried to isolate the substance responsible and he succeeded around 1912. Because that substance contain an amine group, he called it vitamine. It was later to be known as vitamin B3 (niacin), although he thought that it would be thiamine and described it as "anti-beri-beri-factor". He put forward the hypothesis that other diseases, like rickets, pellagra, sprue and scurvy could also be cured by vitamins.[6] The "e" at the end of vitamine was later removed when it was realized that vitamins need not be nitrogen containing amines.

He later postulated the existence of other essential nutrients, which became known as B1, B2, C, and D. In 1936 he determined the molecular structure of thiamin, though he was not the first to isolate it.

Funk also conducted research into hormones, diabetes, ulcers, and the biochemistry of cancer.

The Polish Institute of Arts and Sciences of America (PIASA) annually honors Polish-American scientists with the Casimir Funk Natural Sciences Award. Past winners include Nobel Laureate Roald Hoffmann, Aleksander Wolszczan, Hilary Koprowski, Peter T. Wolczanski, Wacław Szybalski and Benoît Mandelbrot.

Funk returned to the USA In 1940 he became the president of the Funk Foundation for Medical Research and ended his career in pursuit of orally active spleenic extracts.
