Henrik Dam, Danish Biochemist

Henrik Dam (February 21, 1895 - April 17, 1976) was a Danish biochemist and physiologist. He was awarded the Nobel Prize in Medicine in 1943 for joint work with Edward Doisy work in discovering vitamin K and its role in human physiology. Dam's key experiment involved feeding a cholesterol-free diet to chickens. The chickens began hemorrhaging and bleeding uncontrollably after a few weeks. Dam isolated the dietary substance needed for blood clotting and called it the "coagulation vitamin", which became shortened to vitamin K. He died in 1976 at the age of 81.
