Casimir Funk

Casimir Funk was a Polish biochemist generally credited with being among the first to formulate the concept of vitamins after publishing a landmark medical writing in 1912. He highlighted these "vital amines" as critical in fighting significant diseases such as pellagra and rickets, and his analysis influenced a major shift in scientific thinking. His scientific work involved research in Poland, France and the United Kingdom. In 1920, he became a citizen of the United States where he continued his work.
