The isolation of a substance from rice bran in 1911 launched a fundamental shift in nutritional science, leading to the identification of vitamins. Kazimierz Funk, who later adopted the name Casimir, formulated the definitive theory that specific dietary deficiencies cause ailments such as beriberi, pellagra, and rickets, permanently altering how medicine interprets diet-related health events.
Academic Formation and Early Research
Born in Warsaw in 1884, Funk pursued advanced studies in chemistry, earning his doctorate from the University of Bern by age twenty in 1904. His early professional life involved roles at the Pasteur Institute, the University of Berlin, the Lister Institute, and the Wiesbaden Municipal Hospital. These appointments allowed him to refine his biochemical techniques across Europe during a period of significant scientific development.

In 1912, Funk published a landmark paper and book titled The Vitamines, proposing that substances containing amine groups were essential for health. He postulated the existence of four distinct vitamins aimed at preventing beriberi, scurvy, pellagra, and rickets. Although later research confirmed that these substances were not always nitrogen-containing amines, leading to the removal of the final letter, his nomenclature provided the foundational framework for the field.
International Career and Later Contributions
Funk moved to the United States in 1915, eventually obtaining citizenship in 1920. He balanced his research between the U.S. and Europe, serving as the head of the National Institute of Hygiene in Poland between 1923 and 1927. His later work included determining the molecular structure of thiamine in 1936 and investigating hormones, peptic ulcers, and the biochemical origins of neoplasms before his death in Albany in 1967.

Questions readers ask
Did Casimir Funk discover all vitamins?
No. He formulated the theory of vitamins and was the first to isolate a vitamin, specifically the substance now known as vitamin B1, from rice bran.
Why is the term vitamine spelled without an 'e' today?
Funk originally named them 'vitamines' because he believed they were vital amines. The 'e' was dropped when scientists realized these nutrients did not always contain nitrogen-containing amine groups.
