He made many important contributions to mine safety, investigating principally the action of gases, the use of rescue equipment, and the incidence of pulmonary disease. He devised a decompression apparatus for the safe ascent of deep-sea divers, and in 1905 he discovered that regulation of breathing is determined by the effect of the amount of carbon dioxide in the blood on the respiratory center of the brain. He studied barometric pressure on an expedition to Pikes Peak, Colo., in 1911. He founded the Journal of Hygiene, and his published works include Organism and Environment (1917), New Physiology (1919), Respiration (1922), and The Philosophy of a Biologist (1936).

Haldane, John Scott

(born May 3, 1860, Edinburgh, Scot.—died March 14/15, 1936, Oxford, Oxfordshire, Eng.) British physiologist and philosopher. He developed procedures for studying the physiology of breathing and of the blood and devices for measuring hemoglobin and for analyzing blood gas and mixtures of gases. He discovered that breathing is regulated in large part by the effect of the amount of carbon dioxide in the blood on the brain's respiratory centre. He studied the effects of low air pressure, investigated the action of gases in mine suffocations and explosions (an important contribution to mine safety), and developed a staged decompression method for ascent from deep-sea dives. He also tried to clarify the philosophical basis of biology. He was the brother of Richard Burdon Haldane and the father of J.B.S. Haldane.
