Alfred Neuhaus (mineralogist)

from Wikipedia, the free encyclopedia

Alfred Oscar Wilhelm Neuhaus (born February 11, 1903 in Kiel , † January 15, 1975 in Bonn ) was a German geochemist and mineralogist who is considered to be one of the last universal mineralogists in Germany. The first diamond synthesis in Germany was carried out in 1965 in his high-pressure synthesis laboratory .

Life

Alfred Neuhaus was the son of the beverage manufacturer Max Neuhaus and his wife Mathilde, nee Becker. He studied from 1922 at the University of Kiel chemistry and mineralogy, and was in 1927 when Kurt Spangenberg with his thesis measurements of geometric shift speeds in NaCl and their dependence on limit type, concentration and solution Comrade Dr. phil. PhD . The investigations carried out as part of his dissertation were the subject of lively discussions with Walther Kossel , who held the chair for theoretical physics in Kiel, and with Iwan Stranski , who was in Kiel for a colloquium lecture in the summer of 1928, and formed an important experimental underpinning of the Kossel- Stranski's theory of crystal growth.

Alfred Neuhaus remained as an assistant at the Mineralogical-Petrographic Institute of the University of Kiel until 1930 and then followed his teacher Kurt Spangenberg to the University of Breslau in 1930 , where he completed his habilitation in 1932 under the supervision of Erich Bederke . In 1936 he switched to the Bergakademie in Freiberg (Saxony) as a lecturer , where he became an adjunct professor in 1939.

In 1940 he became associate professor for mineralogy at the newly established chair for mineralogy and crystallography at the Technical University of Darmstadt . The institute, which he set up with great effort, was completely destroyed in a bomb attack on Darmstadt in 1944.

After the end of the Second World War , he initially worked in the crystal laboratory of the Leitz company in Wetzlar from 1946 to 1949 . In 1951 he refused a simultaneous call to Munich and followed a call to the Rheinische Friedrich-Wilhelms-Universität Bonn . As full professor of mineralogy and director of the Mineralogical-Petrographic Institute and Museum, he built a modern institute in Poppelsdorf Castle , where he worked until his retirement in 1972.

In Bonn his research activities were in the areas of epitaxy , high pressure, high temperature research (e.g. diamond synthesis) and neutron scattering .

He had been married to Pauline, nee Sörensen, since 1930.

Awards and honors

In 1961 he was elected a member of the German Academy of Natural Scientists Leopoldina in the Mineralogy, Crystallography and Petrology Section and in 1963 he was accepted as a member of the Rheinisch-Westfälische Akademie der Wissenschaften .

In 1968 the Free University of Berlin made him an honorary doctorate in natural sciences.
