"Vitamines" become vitamins through efforts by British nutritional biochemist J. C. (Jack Cecil) Drummond, 29, who observes that not all coenzymes are amines (see Funk, 1911). Drummond labels the fat-soluble vitamin "A," the water-soluble vitamin "B," and the antiscorbutic vitamin "C," and with help from O. Rosenheim finds that the human liver can produce vitamin A from the provitamin carotene widely available in fruits and vegetables.
E. V. McCollum discovers a substance in cod-liver oil that can cure rickets and xerophthalmia. He has been at Johns Hopkins since 1917 (see 1921; Mellanby, 1918; vitamin D, 1922).
