Schack August Steenberg Krogh (November 15, 1874 – September 13, 1949) was a Danish professor with partly Romani background (Romani mother) at the department of zoophysiology at the University of Copenhagen from 1916-1945. He contributed a number of fundamental discoveries within several fields of physiology, and is famous for developing the Krogh Principle.
In 1920 August Krogh was awarded the Nobel Prize in Physiology or Medicine for the discovery of the mechanism of regulation of the capillaries in skeletal muscle. Krogh was first to describe the adaptation of blood perfusion in muscle and other organs according to demands through opening and closing the arterioles and capillaries.
