August Rippel-Baldes

from Wikipedia, the free encyclopedia

August Rippel-Baldes (born November 1, 1888 in Birkenfeld (Nahe) , † September 25, 1970 in Göttingen ) was a German microbiologist.

Life

Rippel was the son of a businessman and from 1907 studied natural sciences in Göttingen , Munich and Marburg , where he was awarded a doctorate degree in botany in 1913 with a dissertation on waterways in leaves phil. received his doctorate. He then went to the Agricultural Research Institute Augustenberg (Baden) as an assistant . Here he dealt with agricultural chemistry topics and worked successfully as a vine grower.

In Munich he became a member of the Cimbria fraternity in 1907 .

From 1917 Rippel worked at the Institute for Agricultural Chemistry and Bacteriology at the University of Breslau . In 1919 he completed his habilitation there with a study of the influence of dry soil on the anatomical structure of plants. In 1923 he accepted a call as a full professor at the University of Göttingen . As Alfred Koch's successor , he became director of the Agricultural-Bacteriological Institute, which he renamed the Institute for Microbiology in 1935. He worked here until his retirement in 1958.

During the National Socialist era , on November 11, 1933, he signed the German professors' confession of Adolf Hitler .

Research services

As a professor at the University of Göttingen, Rippel was instrumental in shaping the development of microbiology into an independent scientific discipline. This is also reflected in his research. After initially continuing the agricultural bacteriological studies of nitrogen conversion in soils that his predecessor Alfred Koch had begun, he soon expanded the research topic to other areas of his specialist field. At his institute he worked on issues relating to the morphology, systematics and physiology of microorganisms, examined energy balances of various types of metabolism and the vital necessity of trace elements for soil bacteria. A research focus was the further development of chemical-bacteriological examination methods.

Rippel is the author of several specialist books. His most important work is the textbook Grundriß der Mikrobiologie , which first appeared in 1947 and was followed by revised editions in 1952 and 1955. Together with Johannes Behrens , Rippel founded the Archive for Microbiology in 1930 , which he managed and edited as editor for almost 40 years. Since 1939 he was a member of the Academy of Sciences in Göttingen . In 1957 the University of Giessen awarded him an honorary doctorate.

In order to avoid confusion with a microbiologist of the same name, August Rippel added his family name and his mother's maiden name. During the last decades of his life he called himself "Rippel-Baldes".
