Carl Wilhelm Hahn
Carl Wilhelm Hahn (Lat. ''Carolus Guilielmus Hahn'', 16 December 1786 – 7 November 1835) was a German zoologist and author of the first German monograph on spiders. C. W. Hahn was an all-round natural scientist – not at all unusual for his time. Surprisingly, he seems to have been almost forgotten. Even the few biographical dates that have been published in secondary literature are not always correct as clarified by P. Sacher in his "attempt at a Biography". Life and lifework Carl Wilhelm Christian Hahn was born in Weingartsgreuth, Upper Franconia, as the first son of Johann Michael Hahn (1734–1824), who was court and palace gardener on the estate of Friedrich Heinrich von Seckendorff, Baron von Seckendorff, later palace gardener for Count Friedrich von Pückler. He obeyed the general call to arms as early as 1813, and served as a quartermaster, and in 1816, received his honourable discharge. Afterwards, he lived with his parents in Fürth, and according to Hahn, made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoologist
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hahniidae
Dwarf sheet spiders (Hahniidae) is a family of araneomorph spiders, first described by Philipp Bertkau in 1878. Their bodies are about long, and they build extremely delicate webs in the form of a sheet. Unlike many spiders the web does not lead to a retreat. The silk used in these webs is so fine that they are difficult to spot unless they are coated with dew. They greatly favor locations near water or near moss, and are often found in leaf litter and detritus or on the leaves of shrubs and trees. Description They are characterized by the arrangement of their six spinnerets in a transverse row. The last segment of the outer spinnerets is quite long and stands out above all the others. Distribution Hahniidae are a worldwide family. The genera of the Northern Hemisphere and Africa tend to differ in their genital structures from those of the Southern Hemisphere. Very few species have been described from southeast Asia, although quite a number seems to be yet undescribed. Name The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century German Zoologists
The 19th (nineteenth) century began on 1 January 1801 (Roman numerals, MDCCCI), and ended on 31 December 1900 (Roman numerals, MCM). The 19th century was the ninth century of the 2nd millennium.

Naturforschenden Gesellschaft In Danzig
The Naturforschende Gesellschaft in Danzig (translated Danzig Research Society, la, Societas Physicae Experimentalis, pl, Gdańskie Towarzystwo Przyrodnicze) was a scientific organization, founded in 1743 in Danzig ( Gdańsk), Poland, which continued in existence until 1936. The ''Societas Physicae Experimentalis'' (Experimental Physics Society) was one of the oldest research societies in the Polish–Lithuanian Commonwealth and in Central and Eastern Europe. History Already in 1670, the physician Israel Conradi (1634–1715) had tried to organize a scientific society in the city, without success. Several others tried after him, until Daniel Gralath (1708–1767) finally succeeded. His father-in-law was Jacob Theodor Klein (1685–1759), a city secretary and also a very distinguished scientist, nicknamed ''Gedanensium Plinius''. At the end of 1742, Gralath had gathered a group of learned men for his purpose, an ''Experimental Physics Society'' (Societas Physicae Experimenta ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...
