Henryk Fryderyk Hoyer
Henryk Fryderyk Hoyer (26 April 1834 – 3 July 1907) was a Polish physician and professor at the University of Warsaw who is considered the founder of histology in Poland. He wrote the first textbook on histology in Polish in 1862. He is sometimes referred to as Henryk Hoyer (senior) to differentiate him from his son, the anatomist Henryk Ferdynand Hoyer. Hoyer's medium and Hoyer's solution are named after him. Life and work Hoyer was born in Inowrocław to pharmacist Ferdynand Hoyer and Helena née Trzcińska who died shortly after his birth. He went to school in Inowrocław and Bydgoszcz before studying medicine at Wrocław and Berlin. He was influenced by the teachings of Rudolf Virchow, Johannes Müller, and Ernst Haeckel.

Rudolf Virchow
Rudolf Ludwig Carl Virchow (; or ; 13 October 18215 September 1902) was a German physician, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician. He is known as "the father of modern pathology" and as the founder of social medicine, and to his colleagues, the "Pope of medicine". Virchow studied medicine at the Friedrich Wilhelm University under Johannes Peter Müller. While working at the Charité hospital, his investigation of the 1847–1848 typhus epidemic in Upper Silesia laid the foundation for public health in Germany, and paved his political and social careers. From it, he coined a well known aphorism: "Medicine is a social science, and politics is nothing else but medicine on a large scale". His participation in the Revolution of 1848 led to his expulsion from Charité the next year. He then published a newspaper ''Die Medizinische Reform'' (''The Medical Reform''). He took the first Chair of Pathological Anatomy at the University of Wü ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Gum Arabic
Gum arabic, also known as gum sudani, acacia gum, Arabic gum, gum acacia, acacia, Senegal gum, Indian gum, and by other names, is a natural gum originally consisting of the hardened sap of two species of the '' Acacia'' tree, ''Senegalia senegal'' and ''Vachellia seyal.'' The term "gum arabic" does not legally indicate a particular botanical source, however. The gum is harvested commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, so retained its name. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft-drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient ...

Chloral Hydrate
Chloral hydrate is a geminal diol with the formula . It is a colorless solid. It has limited use as a sedative and hypnotic pharmaceutical drug. It is also a useful laboratory chemical reagent and precursor. It is derived from chloral (trichloroacetaldehyde) by the addition of one equivalent of water. History Chloral hydrate was discovered in 1832 by Justus von Liebig in Gießen when a chlorination ( halogenation) reaction was performed on ethanol. Its sedative properties were observed by Rudolf Buchheim in 1861, but described in detail and published only in 1869 by Oscar Liebreich; subsequently, because of its easy synthesis, its use became widespread. It was widely used for sedation in asylums and in general medical practice, and also became a popular drug of abuse in the late 19th century. One recreational user was the poet and illustrator Dante Gabriel Rossetti. Chloral hydrate is soluble in both water and ethanol, readily forming concentrated solutions. A solution of c ...

Acetobacter
''Acetobacter'' is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus ''Acetobacter'' is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus ''Acetobacter'' have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures. History of research The acetic fermentation was demonstrated by Louis Pasteur, who discovered the first acetobacter - ''Acetobacter aceti'' - in 1864. In 1998, two strains of ''Acetobacter'' isolated from red wine and cider vinegar were named '' Acetobacter oboediens'' and ''Acetobacter pomorum''. In 2000, ''Acetobacter oboediens'' and '' Acetobacter intermedius'' were transferred to ''Gluconacetobacter'' on the basis of 16S rRNA sequencing. In 2002, '' Acetobacter cerevisiae'' and '' Acetobacter malorum'' were identified b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
