Curt Alfred Herbst
Curt Alfred Herbst (29 May 1866 – 9 May 1946) was a German embryologist and zoologist who studied development of cells and tissues. He noted the mechanosensory organs now known as '' Herbst corpuscles'' in the bills of birds. Herbst was born to Heinrich and Henriette Martin in Meuselwitz, Thuringia. He was educated in Geneva and Jena where his teachers included Carl Vogt and Ernst Haeckel. He also went to the Polytechnic in Zurich to study chemistry. He studied echinoderm larvae and noted the effect of lithium ion gradients on morphogenesis and noted sex-determination in ''Bonellia viridis'' through environmental concentrations of ions. After obtaining a Ph.D. in 1889 he visited Southeast Asia along with Hans Driesch, visiting Ceylon, Java and the Trieste marine station. He then went to Heidelberg to study under Otto Bütschli and became an associate professor in 1906. He received an honorary doctorate from the University of Halle. His students included Helmuth Plessner Helmu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbst Corpuscles
The corpuscles of Herbst or Herbst corpuscles are nerve-endings similar to the Pacinian corpuscle, found in the mucous membrane of the tongue, in pits on the beak and in other parts of the bodies of birds. They differ from Pacinian corpuscles in being smaller and more elongated, in having thinner and more closely placed capsules, and in that the axis-cylinder in the central clear space is encircled by a continuous row of nuclei. They are named after the German embryologist Curt Alfred Herbst. In many wading birds, a large number of Herbst corpuscles are found embedded in pits on the mandible In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movabl ... that are believed to enable birds to sense prey under wet sand or soil. References External links Description at sciencedaily.com* ...

Meuselwitz
Meuselwitz () is a town in the Altenburger Land district, in Thuringia, Germany. It is situated 12 km northwest of Altenburg and 11 km east of Zeitz. History During World War II, a subcamp of the Buchenwald concentration camp operated here. It provided slave labour for HASAG, the third largest consumer of forced labour during the war. All satellites of Buchenwald were HASAG factories. The Meuselwitz plant used 1,666 prisoners, of which, 1,376 were women. The SS charged less for women; they had a higher mortality rate. Wintersdorf has been part of the town Meuselwitz since December 1, 2007. People * Wolfgang Hilbig Wolfgang Hilbig (31 August 1941 2 June 2007) was a German writer and poet.

Carl Vogt
August Christoph Carl Vogt (; 5 July 18175 May 1895) was a German scientist, philosopher, popularizer of science, and politician who emigrated to Switzerland. Vogt published a number of notable works on zoology, geology and physiology. All his life he was engaged in politics, in the German Frankfurt Parliament of 1848–49 and later in Switzerland. Early life Vogt was born in Giessen, the son of , professor of clinics, and Louise Follenius. His maternal uncle was Charles Follen. From 1833 to 1836, he studied medicine at the University of Giessen, and continued his training in Berne, Switzerland, earning his PhD. in 1839. He then worked with Louis Agassiz in Neuchâtel. Career In 1847 he became professor of zoology at the University of Giessen, and in 1852 professor of geology and afterwards also of zoology at the University of Geneva. His earlier publications were on zoology. He dealt with the Amphibia (1839), Reptiles (1840), with Mollusca and Crustacea (1845) and more gener ...

Ernst Haeckel
Ernst Heinrich Philipp August Haeckel (; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', '' phylum'', ''phylogeny'', and ''Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his ''Kunstformen der Natur'' ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic mo ...

Bonellia Viridis
''Bonellia viridis'', the green spoonworm, is a marine worm (class Polychaeta , phylum Annelida) noted for displaying exceptional sexual dimorphism and for the biocidal properties of a pigment in its skin.Murina, G. (2008). Bonellia viridis Rolando, 1821. In: Read, G.; Fauchald, K. (Ed.) (2016). World Polychaeta database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=110363 on 2016-05-28 Distribution The species is wide-ranging, found in the north-eastern Atlantic Ocean and the Mediterranean Sea. Description The pale- to dark-green female, with a 15 cm-long, round or sausage-shaped body, lives on the sea-floor at a depth of 10 to 100 metres, concealed by burrowing in gravel or hiding in rock crevasses or burrows abandoned by other animals. It has two anchoring hooks underneath its body and an extensible feeding proboscis up to 10 times its body-length. It is mainly a detritivore, feeding also on small animals. ...

Hans Driesch
Hans Adolf Eduard Driesch (28 October 1867 – 17 April 1941) was a German biologist and philosopher from Bad Kreuznach. He is most noted for his early experimental work in embryology and for his neo-vitalist philosophy of entelechy. He has also been credited with performing the first artificial 'cloning' of an animal in the 1880s, although this claim is dependent on how one defines cloning. Early years Driesch was educated at the Gelehrtenschule des Johanneums. He began to study medicine in 1886 under August Weismann at the University of Freiburg. In 1887 he attended the University of Jena under Ernst Haeckel, Oscar Hertwig and Christian Ernst Stahl. In 1888 he studied physics and chemistry at the University of Munich. He received his doctorate in 1889. He travelled widely on field and study trips and lecture-tours, visiting Plymouth, India, Zurich and Leipzig where, in 1894, he published his ''Analytische Theorie der organischen Entwicklung'' or ''Analytic Theory of Organic Dev ...

Otto Bütschli
Johann Adam Otto Bütschli (3 May 1848 – 2 February 1920) was a German zoologist and professor at the University of Heidelberg. He specialized in invertebrates and insect development. Many of the groups of protists were first recognized by him. Life Bütschli was born Frankfurt am Main. He studied mineralogy, chemistry, and paleontology in Karlsruhe and became assistant of Karl Alfred von Zittel (geology and paleontology). He moved to Heidelberg in 1866 and worked with Robert Bunsen (chemistry). He received his PhD from the University of Heidelberg in 1868, after passing examinations in geology, paleontology, and zoology. He joined Rudolf Leuckart at the University of Leipzig in 1869.

Helmuth Plessner
Helmuth Plessner (4 September 1892, Wiesbaden – 12 June 1985, Göttingen) was a German philosopher and sociologist, and a primary advocate of "philosophical anthropology". Life & career Plessner had an itinerant education in Germany between 1910 and 1920. He began studying medicine in Friedburg before moving on to zoology and philosophy in Heidelberg. In Gottingen, he studied phenomenology with Husserl, and finally wrote his "Habititationsschrift" under the guidance of Hans Driesch in Cologne. Plessner then held a professorship in Cologne from 1926 to 1933, when he was forced to resign his position because of Jewish ancestry on his father's side. Living in isolation, Plessner initially fled Germany to Istanbul. He returned to Europe at the invitation of Frederik Jacobus Johannes Buytendijk in the Netherlands.

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. The 19th century was characterized by vast social upheaval. Slavery was abolitionism, abolished in much of Europe and the Americas. The Industrial Revolution, 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 ...
