Hans G. Grimm

from Wikipedia, the free encyclopedia

Hans August Georg Grimm (born October 20, 1887 in Hamburg , † October 25, 1958 in Gauting near Munich ) was a German chemist (physical chemistry).

Life

Grimm first became a businessman, because his family owned a pharmaceutical wholesaler, and then studied food chemistry at the Ludwig Maximilians University in Munich with a doctorate in 1911. After military service in World War I (most recently as a captain in the staff of the Alpine Corps), he chose an academic career and completed his habilitation in physical chemistry with Kasimir Fajans in Munich in 1923 . During this time he applied the findings of the older (Bohr's) quantum theory that was developing at the time in chemistry and was in contact with Arnold Sommerfeld .

In 1924 he became an associate professor for physical chemistry at the University of Würzburg and in 1927 a full professor. In order to devote himself to more application-related questions, he took over the management of a research laboratory at BASF in Oppau in 1929 , but remained an honorary professor in Würzburg until 1948.

Since he did not like the National Socialist political environment, he retired to the Ammersee in 1938 and devoted himself mainly to extensive philosophical studies. However, he still worked as a consultant and in 1939 researched the application of X-ray structure analysis to the study of the nature of chemical bonds. In 1949 he became an honorary professor at the University of Munich.

Grimm dealt intensively with crystal chemistry , allowing himself to be guided by a strong geometric intuition to track down commonalities among inorganic compounds (for example with regard to hard, diamond-like compounds with Sommerfeld or when examining mixed crystals). After it is Grimm Hydridverschiebungssatz named: Adding n H atoms in a hydride compound corresponds to the molecule in chemical properties of the elements n digits to the right in the periodic table. In volume 24 of the handbook of physics from 1927 he wrote the article atomic construction and chemistry .

From 1938 he was a corresponding member of the Academy of Sciences in Göttingen .
