John Scott Haldanewas a Scottish physiologist famous for intrepid self-experimentation which led to many important discoveries about the human body and the nature of gases. Haldane locked himself in sealed chambers breathing potentially lethal cocktails of gases while recording their effect on his mind and body.
Background
John Scott Haldane was born in Edinburgh. He was the son of Robert Haldane and the grandson of the Scottish evangelist James Alexander Haldane. His mother was Mary Elizabeth Burdon-Sanderson, the daughter of Richard Burdon-Sanderson and the granddaughter of Sir Thomas Burdon.
His maternal uncle was the physiologist John Scott Burdon-Sanderson. He was the brother of Elizabeth Haldane, William Stowell Haldane and Richard Burdon Haldane, 1st Viscount Haldane.
Education
Haldane attended Edinburgh Academy, Edinburgh University and the Friedrich Schiller University of Jena. He graduated in medicine from Edinburgh University Medical School in 1884.
From 1887 to 1913, Haldane was on the staff of the department of physiology at Oxford University. He was Gifford Lecturer in the University of Glasgow, Fellow of New College, Oxford, from October 1901, and Honorary Professor of the University of Birmingham. Haldane received numerous honorary degrees.
Haldane died in Oxford at midnight on the night of 14 March/15 March 1936. He had just returned from a trip he had undertaken to investigate cases of heat stroke in the oil refineries in Persia.
Achievements
Haldane became the first to prove the importance of the carbon dioxide concentration in the blood for the regulation of breathing.
He also investigated the transportation of gases in the blood, output of blood from the heart, and the function of the kidney. All this work demonstrated his theory-the importance of organic coordination as one of the main characteristics of living organisms.
Throughout his life, Haldane devoted much attention to the health and safety of miners, particularly that of the coal miners. One of his studies showed the importance of humidity, which limits the highest environmental temperature that can be tolerated by manitoba This study had obvious bearing on heat stroke, one of the troubles encountered in deep mines. To enable deep-sea divers to rise safely to the surface, Haldane devised a method of stage-decompression. In contrast to uniform-decompression, the diver is raised to the surface in a series of steps or stages. An account of his scientific achievements which he presented while he held the Silliman lectureship at Yale University in 1915 are given in Respiration. In addition to his papers, Haldane also wrote several books on the relation of philosophy to the biological and physical sciences.
Sir Henry Newbolt wrote a poem called "For J. S. Haldane", published in his anthology "A Perpetual Memory and other Poems" in 1939.
Haldane was a President of the English Institution of Mining Engineers, a Companion of Honor of the British Court, a Fellow of the Royal Society, a member of the Royal College of Physicians and of the Royal Society of Medicine.
