1910 CASIMIR FUNK (England - Poland - USA) (1884-1967)
A biochemist. While studying a deficiency disease known as beriberi at the Lister Institute in London, Funk found a substance which prevented the disease, and called it a "vitamine." Though it was actually vitamin B, the name was later used to refer to all the vitamin groups. He later also discovered that pellagra, a skin disease found in impoverished areas of the U.S., was caused by a vitamin deficiency, establishing a link between malnutrition and disease.
