John Scott, Bruder von 2), 1860, 1936, brit. Physiologe u. philosoph. Schriftst.; Vertreter des Neovitalismus.
(1860-1936) Scottish physiologist whose studies of the exchange of gases during respiration led to an interest in the health hazards of coal mining and deep-sea diving. His aim was to bridge the gap between theoretical and applied science.
Haldane was born and educated in Edinburgh. He was director of the Mining Research Laboratory (first in Doncaster, then in Birmingham) 1913–28. He also lectured at various universities in the UK, the US, and Ireland.
Haldane devised methods for studying respiration and the blood —the Haldane gas analyzer and an apparatus for determining the blood gas content. Having investigated the danger to miners of suffocation, he turned to the toxicity of carbon monoxide, which is usually present in mines after an explosion, and showed that this gas binds to the hemoglobin in the blood in preference to oxygen.
In 1905, Haldane published his idea that breathing is controlled by the effect of the concentration of carbon dioxide in arterial blood on the respiratory center of the brain. In 1907, he announced a technique of decompression by stages which allows a deep-sea diver to rise to the surface safely; it is still used today.
He also researched the reaction of the kidneys to the water content of the blood, and the physiology of sweating.
Richard Burdon, Viscount H. of Cloan, 1856, 1928, brit. Politiker (Liberaler); 1905–12 Kriegs.-Min., reorganisierte das engl. Heer nach dt. Vorbild.
Viscount Haldane (1856-1928) British Liberal politician. As secretary for war 1905–12, he sponsored the army reforms that established an expeditionary force, backed by a territorial army and under the unified control of an imperial general staff. He was Lord Chancellor 1912–15 and in the Labour government of 1924. His writings on German philosophy led to accusations of his having pro-German sympathies.
