# bio (long form, separated for readability)
bio: |
  Carl Peter Henrik Dam graduated in chemistry from Copenhagen Polytechnic in 1920 and climbed through teaching posts at Danish universities, studying microchemistry in Graz and biochemistry's intersection with sterols. In the early 1930s, he replicated chicken-feeding experiments from Ontario researchers who'd stripped all fat from chick feed with chloroform and noticed the birds hemorrhaged at wound sites. Dam found that adding cholesterol back didn't fix it — something else had been pulled out with the fat, a compound essential for blood coagulation. He called it vitamin K, taking the letter from Koagulationsvitamin in the German journal where he first reported it. Between 1942 and 1945 he worked at the University of Rochester, and in 1943 he and Edward Doisy shared the Nobel Prize in Medicine for the discovery and its physiological role. He attended the first Lindau Nobel meeting in 1951.
