Carl Peter Henrik Dam was a Danish biochemist who, along with Edward A. Doisy, was awarded the Nobel Prize in Physiology or Medicine in 1943. He won the prize “for his discovery of vitamin K”. Born in a modest family of an apothecary and a teacher, he graduated in chemistry from the Copenhagen Polytechnic Institute. After graduation, he began his career as an instructor in chemistry at the School of Agriculture and Veterinary Medicine. Within the next three years, he was appointed instructor in biochemistry at the Physiological Laboratory of the University of Copenhagen. He completed his doctoral thesis on the biological significance of sterines. During that period, while studying the metabolism of sterines in chicken, he discovered vitamin K. After he fed the chickens a restricted cholesterol free diet, he noticed that they suffered from a deficiency disease that caused them to bleed easily and lack blood clotting ability. He credited the disease to the lack of an anti-hemorrhagic vitamin that he demonstrated to be fat-soluble and present in green leaves. He named it vitamin K (Koagulations-Vitamin). In 1939, both he and Doisy, working independently, separated the vitamin from alfalfa. In 1943, they were jointly awarded the Nobel Prize.
