obituary

Max Emil Justus Delbrück (born June 16, 1850 in Bergen auf Rügen , † May 4, 1919 in Berlin ) was a German bacteriologist, fermentation chemist and brewing scientist.

Life

Delbrück came from the Prussian Delbrück family of scholars and civil servants and is a younger brother of the historian Hans Delbrück . The biophysicist and Nobel Prize winner Max Delbrück is his nephew.

Delbrück studied at the Royal Trade Academy in Berlin and then in Greifswald , where he received his doctorate under Heinrich Limpricht in 1872 .

Delbrück was assistant to Max Maercker , professor of agricultural chemistry at the University of Halle and head of an agricultural research institute there when he was appointed head of the research institute of the Association of German Spirits Manufacturers (VLSF) in Berlin in 1874 . In 1883 he also took over the scientific management of the newly founded experimental and teaching institute for brewery (VLB). In addition, from 1874 until his death he was Scientific Director of the Institute for Fermentation and Starch Production . He set up his own test and training facilities for the VLSF and the VLB. In 1885 he founded the mechanical engineering department and in 1903 initiated the course to become a master brewer . In 1899 he was appointed full professor at the Agricultural University and in 1892 a member of the Leopoldina learned society .

From 1877 Delbrück was a member of the Imperial Patent Office in Berlin. Together with Max Maercker he published the magazine for the spirit industry , with Friedrich Hayduck the daily newspaper for breweries with the scientific supplement Wochenschrift für Brauerei .

Delbrück's scientific work particularly concerns the physiology of yeasts and their applications, on which his research exerted a great influence. The lactic acid rod bacterium Lactobacillus delbrueckii is named after him, which together with top-fermenting yeasts characterize the fermentation process of Berliner Weisse (see also Lactobacillus delbrueckii subsp. Bulgaricus ). The second species that bears his name is the sugar yeast Torulaspora delbrueckii , which was originally named Saccharomyces delbrueckii .

The Institute for Fermentation and Starch Production (IfG) was a pioneer in biotechnology , proven particularly through the close cooperation between practice and science. From 1896 yeast and lactic acid cultures were produced there on an industrial scale.

The teaching staff of the agricultural university elected Delbrück " as rector of the university for the term of office from April 1, 1898 to 1900 "; he was given the character of a secret government councilor by “ patent from March 21, 1898 ” and in June 1899 he was finally appointed “ regular professor at the agricultural college ” in Berlin after he had been there “ since 1881 as an assistant professor for fermentation chemistry ” " Professor " was active.

Delbrück's study in the IfG was preserved until the bombing in 1943. With its destruction, the library of the Society for the History of Brewing , which he co-founded in 1913, was also lost. In 1913 he also initiated the establishment of the Society for the History and Bibliography of Alcohol . Delbrück's institute was renamed in 1967 by his successor Hanswerner Dellweg as the Institute for Fermentation Industry and Biotechnology in Berlin (IfGB) . He was also the founder and member of the supervisory board of the barley building company founded in 1919 at the suggestion of Georg Haase .

In 1918 the TH Munich awarded him the Dr.-Ing. E. h. He was a member of the Berlin RSC Corps Cimbria .

His grave in the Wilmersdorf cemetery in Berlin has not been preserved.
