Gottfried Osann
Gottfried Wilhelm Osann (26 October 1796, Weimar – 10 August 1866, Würzburg) was a German chemist and physicist. He is known for his work on the chemistry of platinum metals. He studied natural sciences and became a ''privatdozent'' in physics and chemistry at the University of Erlangen in 1819. Between 1821 and 1823, he occupied the same position at the University of Jena. He taught chemistry and medicine at the University of Dorpat (Dorpat, Governorate of Livonia, Russian Empire; today Tartu, Estonia) from 1823 to 1828, from 1828 at the University of Würzburg. A collaboration with Jöns Jakob Berzelius nearly led to the discovery of ruthenium in 1828. They dissolved platinum ore from the Ural mountains in aqua regia and sifted through the residue. Where Berzelius found nothing, Osann thought he had detected three new metals and named them pluranium (concatenation of ''platinum'' and ''Ural''), ruthenium (after Ruthenia, the Latin name for Rus) and polinium (from the Gree ...

Gottfried William Osann
Gottfried is a masculine German given name. It is derived from the Old High German name , recorded since the 7th century. The name is composed of the elements (conflated from the etyma for 'God' and 'good', and possibly further conflated with ) and ('peace, protection'). The German name was commonly hypocoristically abbreviated as '' Götz'' from the late medieval period. ''Götz'' and variants (including '' Göthe, Göthke'' and ''Göpfert'') also came into use as German surnames. Gottfried is a common Jewish surname as well. Given name The given name ''Gottfried'' became extremely frequent in Germany in the High Middle Ages, to the point of eclipsing most other names in ''God-'' (such as ''Godabert, Gotahard, Godohelm, Godomar, Goduin, Gotrat, Godulf'', etc.) The name was Latinised as ''Godefridus''. Medieval bearers of the name include: *Gotfrid, Duke of Alemannia and Raetia (d. 709) *Godefrid (d. c. 720), son of Drogo of Champagne, Frankish nobleman. *Godfrid Haraldsso ...

19th-century German Chemists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Friedrich Gotthilf Osann
Friedrich Gotthilf Osann (August 22, 1794, in Weimar – 30 November 1858, in Giessen) was a German classical philologist. He was a brother to physician Emil Osann (1787–1842) and chemist Gottfried Osann (1796–1866). He received his education at the Universities of Jena and Berlin, where he was a student of August Boeckh. In 1816 he obtained his PhD, and during the following year undertook an educational journey through Germany, France, Italy and England. In 1821 he was appointed an associate professor of philology at Jena, followed by a full professorship at the University of Giessen in 1825. Literary work Osann was the author of a major work on Greek and Roman literary history The history of literature is the historical development of writings in prose or poetry that attempt to provide entertainment, enlightenment, or instruction to the reader/listener/observer, as well as the development of the literary techniques ..., titled ''Beiträge zur griechisch ...

Philologist
Philology () is the study of language in oral and written historical sources; it is the intersection of textual criticism, literary criticism, history, and linguistics (with especially strong ties to etymology). Philology is also defined as the study of literary texts as well as oral and written records, the establishment of their authenticity and their original form, and the determination of their meaning. A person who pursues this kind of study is known as a philologist. In older usage, especially British, philology is more general, covering comparative and historical linguistics. Classical philology studies classical languages. Classical philology principally originated from the Library of Pergamum and the Library of Alexandria around the fourth century BC, continued by Greeks and Romans throughout the Roman/Byzantine Empire. It was eventually resumed by European scholars of the Renaissance, where it was soon joined by philologies of other European ( Germanic, Celtic), Eura ...

Emil Osann
Emil Osann (May 25, 1787 – January 11, 1842) was a German physician and physiologist from Weimar. He was a founder of scientific balneology. He was the brother of philologist Friedrich Gotthilf Osann (1794-1858) and chemist Gottfried Osann (1796-1866). He studied medicine in Jena and Göttingen, and later worked an assistant in a Berlin polyclinic founded by his uncle, Christoph Wilhelm Hufeland (1762–1836). In 1826 he became a full professor of ''Heilmittellehre'' (medical instruction), and in 1833 became director of the aforementioned clinic. Osann is remembered for his work on the effects of mineral springs from a physical and medical standpoint. Among his writings was a two-volume work on European mineral spas, titled ''Physikalisch-medicinische Darstellung der bekannten Heilquellen der vorzüglichsten Länder Europas''. It is considered to be the first comprehensive publication in the field of balneology. In 1837 Osann became sole editor of the ''Journal der praktische ...

Balneologist
Balneotherapy ( la, balneum "bath") is a method of treating diseases by bathing, a traditional medicine technique usually practiced at spas. Since ancient times, humans have used hot springs, public baths and thermal medicine for therapeutic effects. While it is considered distinct from hydrotherapy, there are some overlaps in practice and in underlying principles. Balneotherapy may involve hot or cold water, massage through moving water, relaxation, or stimulation. Many mineral waters at spas are rich in particular minerals such as silica, sulfur, selenium, and radium. Medicinal clays are also widely used, a practice known as 'fangotherapy'. Definition and characteristics "Balneotherapy" is the practice of immersing a subject in mineral water or mineral-laden mud; it is part of the traditional medicine of many cultures and originated in hot springs, cold water springs, or other sources of such water, like the Dead Sea. Presumed effect on diseases Balneotherapy may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polonium
Polonium is a chemical element with the symbol Po and atomic number 84. Polonium is a chalcogen. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. Due to the short half-life of all its isotopes, its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores, as it is the penultimate daughter of natural uranium-238. Though slightly longer-lived isotopes exist, they are much more difficult to produce. Today, polonium is usually produced in milligram quantities by the neutron irradiation of bismuth. Due to its intense radioactivity, which results in the radiolysis of chemical bonds and radioactive self-heating, its chemistry has mostly been investigated on the trace scale only. Polonium was discovered in July 1898 by Marie Sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
