Casimir Funk
Casimir Funk (Polish: Kazimierz Funk [kaˈʑimjɛʂ ˈfuŋk]; February 23, 1884 – November 19, 1967) was a Polish biochemist generally credited with being among the first to formulate the concept of vitamins (the first being the English chemist Frederick Gowland Hopkins) after publishing a landmark medical writing in 1912. He highlighted these "vital amines" (or "vitamines") as critical in fighting significant diseases such as pellagra and rickets, and his analysis influenced a major shift in scientific thinking.
