Maximilian Neisser (born June 19, 1869 in Liegnitz , Silesia , † February 25, 1938 in Frankfurt am Main ) was a German bacteriologist and hygienist.

family

Max Neisser was the son of Salomon Neisser and Julie Sabersky. The dermatologist Albert Neisser was his uncle. In 1901 Neisser married Emma Eleonore Hallgarten (1878-1939), her father was the philanthropist Charles Hallgarten . The marriage resulted in the children Elise Charlotte , Gerhard Ernst and Klaus Alfred.

education and profession

Neisser first studied natural sciences for a few semesters and then medicine in Freiburg , Breisgau and Berlin . After the state examination, he received his doctorate in 1893 with an investigation into the differentiation between cholera vibrions and the water vibrio ( Vibrio berolinensis) that he had discovered. This work, which also contains the description of a procedure for the detection of cholera vibrions, was created in the laboratory of the Berlin hygienist Max Rubner .

From 1894 to 1899 Neisser worked as an assistant to the hygienist Carl Flügge (1847–1923) at the Breslau Hygiene Institute. After his habilitation in 1899, he was a member of the Institute for Experimental Therapy in Frankfurt am Main until 1909 , which was headed by Paul Ehrlich . Appointed professor, he took over the management of the new Frankfurt Hygiene Institute in 1909. From 1914 Neisser represented the subjects of hygiene and bacteriology as full professor at the University of Frankfurt . During the First World War he served as an advisory army hygienist. In 1933 Neisser was forcibly retired from the Nazi regime and then lived in retirement in his country house in Falkenstein im Taunus .

power

Neisser primarily dealt with hygienic and bacteriological issues such as the transmission of infectious agents in drinking water or air dust and the differential diagnosis of diphtheria bacillus (1897). Among other things, Neisser described a steam process for disinfecting drinking water wells. In addition, he dealt with "applied" bacteriology and hygiene in public health (water, food, home hygiene, heating , ventilation , milk disinfection ) as well as the further development of bacteriological process technologies (nutrient media, sterilization , animal husbandry), questions of laboratory infection and bacteriological warfare .

He researched the properties of numerous microorganisms (diphtheria bacillus, staph, streptococci , pneumococci , meningococci , gonococci , anthrax , plague , Friedlander , snot bacilli ). In 1901, Neisser demonstrated that staphylococci form two different soluble poisons in blood serum ( hemolysin and leukocidin).

Neisser developed a biological test for protein differentiation in order to be able to differentiate between different types of blood (Neisser-Sachs complement fixation reaction) and showed that excess immune serum can mask the antigen-antiserum reaction (Neisser-Wechsberg phenomenon).
