Karl Hugo Strunz
Karl Hugo Strunz (24 February 1910 – 19 April 2006) was a German mineralogist. He is best known for creating the Nickel-Strunz classification, the ninth edition of which was published together with Ernest Henry Nickel. Biography Strunz was born on 24 February 1910 in Weiden in der Oberpfalz ( Upper Palatinate, Bavaria, Germany). He attended the 'Goethe-Oberrealschule Regensburg', a high school with a strong scientific background in Regensburg. In 1929 he began his studies in natural sciences at the University of Munich and specialized in Mineralogy. He received his doctorate degree in philosophy in 1933 from the University of Munich and two years later his doctorate degree in technical sciences from the Technical University Munich. After he graduated he was granted a research scholarship at the Victoria University (Manchester, England) where he worked with William Lawrence Bragg. He then went on to the ETH Zurich (Switzerland), where he was an assistant to Paul Niggli. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weiden In Der Oberpfalz
Weiden in der Oberpfalz (, ; official abbreviation: Weiden i.d.OPf.; Northern Bavarian: ''Weidn in da Owapfalz'') is a district-free city in Bavaria, Germany. It is located east of Nuremberg and west of the Czech border. Weiden is the second biggest city in the governmental district Oberpfalz, next to Regensburg. A branch of the German Army is located here. History Weiden in der Oberpfalz was first mentioned in a document in 1241 as Weiden. It is assumed that the first settlements in Weiden are dated the year 1000. Located at the intersection of two major trading routes (Goldene Strasse and Magdeburger Strasse), Weiden soon became an important trading center with a population of 2,200 in 1531. Two city fires, the Thirty Years' War and the Plague gave the city setbacks, which it didn't recover from until the end of the 18th Century. Between 1634 and 1635, as well as between 1648 and 1650; Weiden was occupied by Swedish troops. Since 1714 the city fully belonged to the Duchy of ...

International Mineralogical Association
Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS). The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The last meeting was scheduled in 2022 in Lyon, France. Presidents The presidents of the IMA have been: * since 2024: Eiji Ohtani ** Tohoku University * 2022–2024: Hans-Peter Schertl ** Bochum University * 2020–2022: Anhuai Lu ** Peking University *2018–2020: Patrick Cordier ** Université de Lille *2016–2018: Peter C.

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The Geology, geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock (geology), rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate (geology), aggregate of two or more different types of minerals, spaci ...

Emeritus
''Emeritus/Emerita'' () is an honorary title granted to someone who retires from a position of distinction, most commonly an academic faculty position, but is allowed to continue using the previous title, as in "professor emeritus". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished performance (usually in the area of research) awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title. The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In descriptions of deceased professors emeriti listed at U.S. universities, the title ''emeritus'' is replaced by an indication of the years of their appointments, except in obituaries, where it may be us ...

Paul A. Ramdohr (1 January 1890 in Überlingen – 8 March 1985 in Hohensachsen/Weinheim), was a German mineralogist, ore deposit-researcher and a pioneer of ore microscopy. Life After attending school at the "Alten Gymnasium" of Darmstadt and studying at the University of Heidelberg, he earned his Doctorate in 1919 under the direction of Otto Mügge in Göttingen with a Dissertation on Basalts of the Blauen Kuppe near Eschwege.

Museum Für Naturkunde
The Natural History Museum () is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major museums in Germany alongside Naturmuseum Senckenberg in Frankfurt and Museum Koenig in Bonn. The museum houses more than 30 million Zoology, zoological, Paleontology, paleontological, and Mineralogy, mineralogical specimens, including more than ten thousand type specimens. It is famous for two exhibits: the largest mounted dinosaur in the world (a ''Giraffatitan'' skeleton), and a well-preserved specimen of the earliest known bird, ''Archaeopteryx''.

Paul Niggli
Paul Niggli (26 June 1888 – 13 January 1953) was a Swiss crystallographer, mineralogist, and petrologist who was a leader in the field of X-ray crystallography. Education and career Niggli was born in Zofingen and studied at the Swiss Federal Institute of Technology (ETH) in Zürich and the University of Zurich, where he obtained a doctorate. His 1919 book, ''Geometrische Kristallographie des Diskontinuums'', played a seminal role in the refinement of space group theory. In this book, Niggli demonstrated that although X-ray reflection conditions do not always uniquely determine the space group to which a crystal belongs, they do reveal a small number of possible space groups to which it could belong. Niggli used morphological methods to account for internal structure and, in his 1928 ''Kristallographische und Strukturtheoretische Grundbegriffe,'' he took up what is essentially the reverse process, the task of establishing the connection between space lattices and external cry ...
