Karl Hugo Strunz

from Wikipedia, the free encyclopedia

Karl Hugo Strunz , shortly Hugo Strunz (* 24. February 1910 in Weiden , † 19th April 2006 in Unterwössen ), was a German mineralogist , academics and developers of modern classification of minerals ( see also: classification of minerals by Strunz in the 8th or 9th edition ).

Education and degrees

After completing high school in Regensburg Hugo Strunz began in 1929 in Munich, the study of natural sciences with an emphasis on mineralogy and received his 1933 promotion to Dr. of philosophy at the Ludwig Maximilians University in Munich . Two years later he received his doctorate in technical sciences at the TH Munich .

In 1937 Strunz came to the Mineralogical Museum in Berlin and became an assistant to Paul Ramdohr (1890–1985) and qualified as a professor in 1938.

From 1939 until the end of the Second World War he taught as a lecturer in mineralogy and petrography at the Friedrich Wilhelm University (since 1946 Humboldt University in Berlin ) in Berlin. He then taught mineralogy at the Philosophical-Theological University in Regensburg , where he founded a Mineralogical-Geological Institute, which was later expanded to become the State Research Institute for Applied Mineralogy.

In 1951, Strunz received the chair for mineralogy and petrography at the TU Berlin , where he set up a mineralogical institute in just a few years, where he worked until his retirement in 1978. During this time over 200 publications were made.

On his mineralogical research trips, Strunz visited most countries in Europe and some countries in Africa, including Madagascar , Namibia , Zimbabwe and Tanzania .

He was a founding member of the International Mineralogical Association (IMA) and from 1958 to 1970 chairman of the Mineral Data Commission , from 1982 vice chairman. After his retirement , Strunz became curator of the Mineralogical Museum in his home country.

Outstanding performance

Karl Hugo Strunz developed a mineral classification for minerals on the basis of their chemical composition and crystal structure, consisting of nine mineral classes (previously and since 2001 ten mineral classes), which appeared for the first time in 1941. Since then, these "mineralogical tables" have been continuously adapted to the current state of knowledge, translated into several languages ​​and are now a standard work for mineral systematists.

He discovered and described 14 new minerals such as Laueit , Hagendorfit , Chudobait , Fleischerit , Stranskiit , Liandradit and Petscheckit .

Works (excerpt)

The best-known work by Strunz are the Mineralogical Tables , a complete work on the classification of minerals on a crystal-chemical basis with an introduction to crystal chemistry, which appeared for the first time in 1941. The 4th edition was completely revised and expanded in 1966 with the help of Christel Tennyson , updated again and again up to the 8th edition in 1982 and translated into several languages. The 9th edition appeared in 2001 in English with the participation of Ernest H. Nickel with the title Mineralogical tables: chemical structural mineral classification system . It contains around 4000 minerals (including 3881 minerals recognized by the International Mineralogical Association ) and 9248 other names such as trade names or mining names.

Another important standard work, Klockmann's Textbook of Mineralogy ( ISBN 3-432-82986-8 ), was completely revised and reissued by Strunz in collaboration with Paul Ramdohr up to the 16th edition in 1978.

As early as 1932, Strunz and Balthasar Gossner published a study on the structural relationships between phosphates (triphylene) and silicates (olivine) and on the chemical composition of ardennite . This was followed by a description of the relationship between the silicates and the phosphates and arsenates (1936) and of the chemical composition and structure of Rhodizite and Jeremejewit (1939).

In 1947 Strunz brought out a geological overview table for Central Europe (including) , which he revised again in 1948. In the same year he endeavored with structure and form to provide an easily understandable introduction to crystal science.

Another deposit description followed in 1953 with minerals and deposits in Eastern Bavaria .

In 1970 Strunz wrote a treatise From the Bergakademie to the Technical University of Berlin and five years later on the mineralogy and geology of the Upper Palatinate .

Honors

In 1985 Hugo Strunz received the Federal Cross of Merit, 1st class. He was an honorary member of over twenty national and international scientific societies and academies such as the German Mineralogical Society , the Mineralogical Society of America , the Mineralogical Society of England , the Gemmological Society of Japan and the Mineralogical Society of the USSR . Since 1995 he was an honorary member of the Münchener Mineralienfreunde e. V.

Furthermore, Strunz was one of the senators of the German Academy of Sciences Leopoldina , to which he belonged from 1968, and holder of the Bořicky Medal of the Charles University in Prague .

The minerals Strunzit , Ferristrunzit and Ferrostrunzit are named after him.
