Макс Йозеф Петтенкофер: Гигиена ғылымын дамытушы және тәжірибеші химик

Bavarian chemist and hygienist (1818–1901)

Max Joseph Pettenkofer, ennobled in 1883 as Max Joseph von Pettenkofer (3 December 1818 – 10 February 1901) was a Bavarian chemist and hygienist. He is known for his work in practical hygiene, as an apostle of good water, fresh air and proper sewage disposal. He was further known as an anti contagionist, a school of thought, named later on, that did not believe in the then novel concept that bacteria were the main cause of disease. In particular he argued in favor of a variety of conditions collectively contributing to the incidence of disease including: personal state of health, the fermentation of environmental ground water, and also the germ in question. He was most well known for his establishment of hygiene as an experimental science and also was a strong proponent for the founding of hygiene institutes in Germany. His work served as an example which other institutes around the world emulated. He returned to his family to marry Helene Pettenkofer. A stipulation of his marriage was that he pursue another career and was advised to pursue medicine. His work in this area was later cited by Dmitri Mendeleev in his construction of the Periodic Table of Elements. The color forming reaction known by his name for the detection of bile acids was published in 1844. In his widely used method for the quantitative determination of carbonic acid the gaseous mixture is shaken up with baryta or limewater of known strength and the change in alkalinity ascertained by means of oxalic acid. He further provided the experimental proof that the mysterious haematinum of ancient times was in fact a copper colored glass.

Pettenkofer's name is most familiar in connection with his work in practical hygiene, as an apostle of good water, fresh air and proper sewage disposal. His attention was drawn to this subject by the unhealthy condition in Munich in the 19th century. Specifically he examined the field of hygiene and determined that there was a minimal amount of rigorous research. He was responsible for transitioning the field of hygiene into a research oriented field. Many of his additions and plans for the city's sewage system are reflected today in the current sewage system layout.

Pettenkofer published his views on hygiene and disease in numerous books and papers; he was an editor of the Zeitschrift für Biologie (together with Carl von Voit) from 1865 to 1882, and of the Archiv für Hygiene from 1883 to 1894. In addition to his research publications he also gave a significant number of lectures to government officials in order to persuade them to provide funding for civic works and governmental oversight committees to promote and assess the state public health. In the same magazine, Pettenkofer is recognized to have developed an accurate quantitative analysis method for determining atmospheric carbon dioxide. The 1899 handwritten manuscript 'On the self purification of rivers' and Pettenkofer's papers can be found at the archives of the London School of Hygiene & Tropical Medicine.

In 1894 he retired from active work, and on 10 February 1901 he shot himself in a fit of depression. He died at his home in the Residenz in Munich. He is buried in the Alter Südfriedhof in Munich.

During his lifetime he received numerous accolades. He was presented with the title of "Honorary Citizen" of Munich and given a gold medal. His work in hygiene precipitated the creation of the "Pettenkofer Foundation for Research in Hygiene" which received funding from the cities of Munich and Leipzig to fund research projects related to Hygiene and Public Health.
