AUGUST KROGH (1874-1949), professor at Copenhagen University, received the 1920 Nobel Prize in physiology or medicine for discovering the causes of capillary constriction and expansion. In 1922 Krogh published his classic Anatomy and Physiology of Capillaries, which showed that capillaries are regulated both by the nervous system and by hormonal secretions. "Many of the scientists who became the most prominent physiologists of the United States in succeeding decades participated in the studies that made up Krogh's famous monograph. His influence on American physiology cannot be overstated" (Magill, Nobel Prize Winners: Physiology or Medicine, p. 210). A very distinguished physiologist, he studied gas exchange in living organisms, the effect of carbon dioxide on oxyhemoglobin dissociation in the blood, the quantitation of blood flow, the exchange of gases in the tissues and the structure and function of the capillaries.
