  Schack August Steenberg Krogh - A Versatile Genius
August Krogh was born in Grenå on Denmark's Jutland peninsula in 1874.
Krogh did not believe this (in his 1903 dissertation, he had studied gas exchange via the skin of frogs - an important part of their breathing - and found that it was a matter of passive diffusion).
August Krogh's wife Marie Krogh, a physician and his research colleague, had become ill with diabetes (the diagnosis was probably made in 1921).

 August Krogh Summary
August Krogh was born on Nov. 15, 1874, in Grenaa, Jutland.
Krogh, in 1912, convincingly delivered the fatal blow to the secretion theory by first showing that in fishes there is no secretion of oxygen into the air sacs, and then by demonstrating that the amount of oxygen in the blood always equalled the amount that should be provided by his diffusion theory.
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.

In collaboration with Bohr and K. Hasselbalch the influence of the CO tension on the oxyhemoglobin dissociation curve of the blood was demonstrated.
This conclusion was strengthened by Krogh in an analysis of the underlying mechanism 1912), which also led to the conclusion that the portal system acts as a general regulator of the pressure in the central veins and thereby on the output of the heart.
Krogh came to this conclusion after he had made experiments on the diffusion capacity of animal tissues, and these considerations were the reason for his famous studies of the capillaries during rest and work.

 Life before model systems: General zoology at August Weismann's institute American Zoologist - Find Articles
He reminds us of and endorses what Hans Krebs once called the "[August] Krogh principle," named after the famous Danish physiologist, who wrote that "For a large number of problems there will be some animal of choice or a few such animals on which it can be most conveniently studied" (Krebs, 1975; Krogh, 1929, p.
Krogh thereby implied that convenience, in a broad sense, and specific problem solving, not a presumptive general model, had and should guide the choice of an organism in research (Gest, 1995).
Developmental biologist Jessica Bolker has provided a thoughtful analysis of some of the shortcomings of a model systems approach: the unavoidable biases in the organism selection process, the confusion of experimental convenience for universality, and a frequent disregard of phylogenetic reality are among the dangers she discusses (Bolker, 1995).

The Danish scientist Shack August Krogh was the first person to demonstrate that capillaries expand in order to meet blood demand.
For many years prior to his discovery, it was mistakenly believed that blood pressure increased in order for more blood to flow through the vessels.
However, Krogh was able to prove that muscles requiring additional blood supplies send signals that trigger the expansion of capillaries and was awarded with the Nobel Prize in 1920 for his efforts.

August Krogh, Hans Christian Hagedorn, and the pharmacist August Kongsted obtained Royal Charters for the non-profit foundation Nordisk Insulinlaboratorium in 1926.

This approach is known as the Krogh Principal, after the late August Krogh, who said, "For many problems there is an animal on which it can be most conveniently studied".
This means that knowing the "best" solution or design for a particular problem, jumping, flying and so on, will enable researchers to understand the most important parameters for systems to function properly.
