Wilhelm Friedrich Von Gleichen
Wilhelm Friedrich von Gleichen-Rußwurm (1717–1783), Stablemaster of the Margrave of Bayreuth, was a German biologist. In 1778 he developed a process of staining micro-organisms with indigo and carmine (''Abhandlung über die Saamen - und Infusionsthierchen, und über die Erzeugung, nebst mikroskopischen Beobachtungen des Saamens der Thiere in verschiedenen Infusionen'' - Treatise on seed and infusoria, and their production, along with microscopic observations of the semen of animals in different suspensions). The fern genus ''Gleichenia'' was named in his honour. Publications''Drosophila : a contribution to its morphology and development'' - W.

Charles Alexander, Margrave Of Brandenburg-Ansbach
Christian Friedrich Carl Alexander (german: Christian Friedrich Karl Alexander; 24 February 1736 – 5 January 1806) was the last margrave of the two Franconian principalities, Bayreuth and Ansbach, which he sold to the King of Prussia, a fellow member of the House of Hohenzollern. Life His parents were Charles William Frederick, Margrave of Brandenburg-Ansbach, and Friederike Luise of Prussia, daughter of King Frederick William I of Prussia, sister of Frederick II of Prussia, a granddaughter of the British King George I and niece of the reigning British King George II (who would die aged 77 and leave his grandson, Charles's second cousin, as King George III, when Charles was 24). After the sudden death of his elder brother Carl Frederick August on 9 May 1737, "Alexander", as he later called himself, became Crown Prince of the principality. From 1748 to 1759, he studied at Utrecht. As the young "Count of Sayn" (the county of Sayn-Altenkirchen in the Westerwald having been ab ...

Drosophila Melanogaster
''Drosophila melanogaster'' is a species of fly (the taxonomic order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the "vinegar fly" or "pomace fly". Starting with Charles W. Woodworth's 1901 proposal of the use of this species as a model organism, ''D. melanogaster'' continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the insect. ''D. melanogaster'' is typically used in research owing to its rapid life cycle, relatively simple genetics with only four pairs of chromosomes, and large number of offspring per generation. It was originally an African species, with all non-African lineages having a common origin. Its geographic range includes all continents, including islands. ''D. melanogaster'' is a common pest in homes, restaurants, and othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
