Walther Kossel

Walther Kossel ( born January 4, 1888 in Berlin, † 22 May 1956 in Tübingen ) was a German physicist and university teacher.

Life

Walther Kossel was born as the son of Albrecht Kossel Medicine Nobel Prize winner and his wife Luise nee Holtzman, the daughter of the philologist Adolf Holtzmann. Walther Kossel was married to Hedwig Olga Kossel ( 1888-1958 ).

As a student of Arnold Sommerfeld Kossel was from 1921 Professor of Theoretical Physics at the Christian- Albrechts- University of Kiel. 1929/30, he was its rector.

In 1932 he moved to the TH Danzig ( Free City of Danzig ). He signed in November 1933, the commitment of the professors at German universities and colleges to Adolf Hitler.

In 1945, he followed the call of the Eberhard Karls University of Tübingen to the Chair of Theoretical Physics. In 1953 he became Professor Emeritus.

Works

Kossels field was mainly the study of the atomic structure and the structure of the molecules. In 1916 he presented based on the then new quantum hypothesis of Niels Bohr on a working hypothesis in the theory of covalent bonding ( valence ). He explored the electromagnetic spectra of the X-ray and gamma radiation and founded in 1928 the theory of crystal growth ( Kossel - Stranski theory ). 1935 saw Walter Kosssel named after him Kossel effect, the interference phenomena of monochromatic X- rays emanating from atoms in a crystal. Also the shift theorem of Kossel -Sommerfeld contributes with his name.

Burial in Heidelberg

In Tübingen died, Kossel was transferred to Heidelberg. It rests on the Heidelberg hill cemetery in honor of his father's grave Albrecht Kossel. In the family grave, his wife and other family members have been buried. Walter Kossels life data are eingemeiselt on a sun stone granite.
