Gahn
{{confused, McGahn, Gahan, Ghan (other){{!Ghan, Gan (other){{!Gan Gahn is a Swedish family, one member of which was ennobled in 1809 with the name ''Gahn af Colquhoun''. The family has claimed an unverified origin in a Scottish family Colquhoun, a claim which was confirmed 1781 in a letter by the Lord Lyon King of Arms, but on dubious grounds, as later research has shown. A claim that the Swedish noble family ''Canonhielm'' is a branch of this family has also been shown to lack genealogical substance. Notable members of the family include: *Johan Gottlieb Gahn (1745–1818), chemist and mineralogist who discovered manganese in 1774, and after whom the mineral gahnite was named. * Henrik Gahn (1747–1816), physician and student of Linnaeus, who pioneered the use of vaccine against smallpox in Sweden in 1803. * Carl Pontus Gahn, ennobled with the name ''Gahn af Colquhoun'' (1759–1825), military officer who participated in the war in Finland in 1788–1789, the cam ...

Johan Gottlieb Gahn
Johan Gottlieb Gahn (19 August 1745 – 8 December 1818) was a Swedish chemist and metallurgist who isolated manganese in 1774. Gahn studied in Uppsala 1762 – 1770 and became acquainted with chemists Torbern Bergman and Carl Wilhelm Scheele. 1770 he settled in Falun, where he introduced improvements in copper smelting, and participated in building up several factories, including those for vitriol, sulfur and red paint. He was the chemist for The Swedish Board of Mines '' Bergskollegium'' from 1773 – 1817. Gahn was however very reluctant to publish his scientific findings himself, but freely communicated them to Bergman and Scheele. One of Gahn's discoveries was that manganese dioxide could be reduced to manganese metal using carbon, becoming the first to isolate this element in its metal form. In 1784, Gahn was elected a member of the Royal Swedish Academy of Sciences. He also made a managerial career in Swedish mining. See also * Gahnite Gahnite, ZnAl2O4, is a rare min ...

Acceptera
''acceptera'' (1931) is a Swedish modern architecture manifesto written by architects Gunnar Asplund, Wolter Gahn, Sven Markelius, Eskil Sundahl, Uno Åhrén, and art historian Gregor Paulsson. Claiming that Swedish “building-art” (''byggnadskonst'') has failed to keep pace with the revolutionary social and technological change sweeping Europe in the early 20th century, the authors argue that the production of housing and consumer goods must embrace a functionalist orientation in order to meet the particular cultural and material needs of both modern society and the modern individual. Combining social analysis with an iconoclastic critique of contemporary architecture and handicraft, ''acceptera'' ardently calls upon its readers not to shrink back from modernity, but rather to “accept the reality that exists—only in that way have we any prospect of mastering it, taking it in hand, and altering it to create a culture that offers an adaptable tool for life.” The manifesto ...

Carl Pontus Gahn Af Colquhoun
Carl Pontus Gahn (1 March 1759 – 9 May 1825) was a Swedish military officer who participated in the Russo-Swedish War in Finland in 1788–1789, the Finnish War campaign in Norway in 1808 and the unsuccessful invasion of Norway at Eidskog in 1814. He was ennobled in 1809, taking the title ''Gahn af Colquhoun'' in acknowledgement of his Scottish ancestry (Gahn was itself a contraction via Cahun of the family name of Colquhoun). He was promoted to the rank of Major General Major general (abbreviated MG, maj. gen. and similar) is a military rank used in many countries. It is derived from the older rank of sergeant major general.

Gahnite
Gahnite, ZnAl2O4, is a rare mineral belonging to the spinel group. It forms octahedral crystals which may be green, blue, yellow, brown or grey. It often forms as an alteration product of sphalerite in altered massive sulphide deposits such as at Broken Hill, Australia. Other occurrences include Falun, Sweden where it is found in pegmatites and skarns; and, in the United States, Charlemont, Massachusetts; Spruce Pine, North Carolina; White Picacho district, Arizona; Topsham, Maine; and Franklin, New Jersey. It was first described in 1807 for an occurrence in the Falu mine, Falun, Dalarna, Sweden, and named after the Swedish chemist, Johan Gottlieb Gahn (1745–1818), the discoverer of the element manganese. It is sometimes called ''zinc spinel''. See also * List of minerals named after people This is a list of minerals named after people. The chemical composition follows name.

Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nordisk Familjebok
''Nordisk familjebok'' (, "Nordic Family Book") is a Swedish encyclopedia that was published in print from between 1876 and 1993, and that is now fully available in digital form via Project Runeberg at Linköping University. Despite their considerable age and relative obsolescence, the public domain editions of the encyclopedia remain important reference works in Finland, especially on Finnish Wikipedia. History First edition ''Nordisk familjebok'' began when Halmstad publisher hired an editor, linguist , in 1874 to publish a six-volume encyclopedia. Linder drew up a plan for the work, designed the editorial team and created a large circle of experts and literary figures, who submitted article proposals and wrote and reviewed them. Under Linder's direction, the articles were then edited to make them as formal, consistent and accurate as possible. Much attention was paid to Nordic subjects, mainly Swedish and Finnish, where sources and models were often lacking, so extensive ...
