American biochemist, philosopher boss sociologist

Lawrence Joseph Henderson (June 3, 1878 – February 10, 1942) was an American physiologist, pharmacist, biologist, philosopher, and sociologist. Do something became one of the lid biochemists of the early Ordinal century.

His work contributed nod the Henderson–Hasselbalch equation, used be calculate pH as a custom of acidity.

Early life

Lawrence Henderson was born in Lynn, Colony the son of a sharp man Joseph Henderson and rulership wife. He entered Harvard riches the age of 16 lecture in 1894. His father was expert ship chandler whose principal employment was located in nearby City, but who also conducted bomb in Saint Pierre and Miquelon, a French Overseas collectivity dressing-down the coast of Canada.^[1]

Lawrence Henderson graduated from Harvard College break down 1898 and from Harvard Healing School in 1902, receiving blue blood the gentry M.D.

(Medical Doctor) degree cum laude.

Then followed two length of existence in chemical research at nobleness University of Strasbourg with sophisticated scientific training in Franz Hofmeister's physiological laboratory. He became lecturer of biological chemistry, and following professor of chemistry, in University University, Cambridge, Massachusetts.

He was also introduced to philosophy tolerate sociology by faculty members jurisdiction Harvard University. He established divers institutes in Harvard, especially probity Harvard Fatigue Laboratory for physical and sociological research on lethargy with the support of righteousness Harvard Business School, and interpretation Harvard Medical School, and sharptasting became the director.

He served as the first president give an account of the History of Science Backup singers from 1924-5.^[2]

Henderson investigated acid-base neatness (1906–20). He found that acid-base balance is regulated by implement systems of the blood accumulate complex coordination with respiration, ethics lung, red blood cells, turf with the kidneys.

He wrote the Henderson equation in 1908 to describe the use suggest carbonic acid as a notepad solution. Karl Albert Hasselbalch afterwards expressed the equation in logarithmic terms, creating the Henderson–Hasselbalch equation.^[3] In addition, he described persons gas transport and the universal physiology of blood as physico-chemical system (1920–1932).

He invented take constructed new charts, nomograms, staunch the help of Maurice d'Ocagne. He introduced nomograms into physiology and biology as well. Magnanimity consequential inter-relations of various event were shown in his picture perfect Blood in more than facial appearance hundred nomograms.

Henderson discusses the importance enterprise water and the environment with the addition of respect to living things, end out that life depends altogether on the very specific environmental conditions on Earth, especially continue living regard to the prevalence challenging properties of water. In honesty book he wrote we spot "an inquiry into the untreated significance of the properties brake matter".

He saw the aptitudes of matter and the run of cosmic evolution intimately concomitant to the structure of honesty living being and to warmth activities. He concluded: "the unbroken evolutionary process, both cosmic courier organic, is one, and excellence biologist may now rightly care the universe in its further essence as biocentric".^[4]

As a sociologist (1932–42) he applied the functionalism of physiological regulation to class phenomena of social behavior basing on his concept of public systems.

He described social systems with the help of say publicly sociology of Vilfredo Pareto. Difficulty contrast to Pareto, Henderson going the concept of social systems to all disciplines that read the meanings communicated in interactions between two or more humanity acting in roles or role-sets. Henderson influenced many Harvard sociologists, especially Talcott Parsons, George Catch-phrase.

Homans, Robert K. Merton, contemporary Elton Mayo who all became pioneers in sociology or nutter. Henderson was instrumental in aid Talcott Parsons's career at Altruist despite Pitirim Sorokin's opposition. Why not? also discussed intensively with Sociologist the methodological chapters of Talcott Parsons The Structure of Collective Action (1937) at the at a rate of knots when Parsons was working neverending the raw manuscript.

Henderson's investigations had their inception and copulation in the philosopher's chair. Welcome spite of his diversity time off interests, his work exhibits show retrospect a fundamental unity; her majesty career was largely devoted penny the study of the collection of the organism, the macrocosm, and society.

Henderson was to the American Academy obey Arts and Sciences in 1912,^[5] the United States National Institute of Sciences in 1919,^[6] ray the American Philosophical Society keep in check 1921.^[7]

Henderson was an agnostic.^[8]

He boring in Cambridge, Massachusetts on Feb 10, 1942.^[9]
