Alfred Kahl
Alfred Detlef Fritz Kahl (18 February 1877 – November, 1946) was a German schoolteacher who took up microscopy in mid-life and became a leading authority on ciliated protozoa. In a burst of scientific productivity that lasted just nine years, he published 1800 pages of scholarly work, in which he described 17 new ciliate families, 57 genera, and about 700 previously unknown species. During his brief career as a protozoologist, he redescribed and illustrated nearly all the species of ciliates known in his time, and fit them into a taxonomic scheme that remains influential today.Foissner, Wilhelm.

Warwerort
Warwerort is a municipality in the ''Amt'' ("collective municipality") Büsum-Wesselburen in the district Dithmarschen in Schleswig-Holstein, Germany. Warwerort is located along the north coast of the Meldorf Bight east of Büsum and Büsumer Deichhausen. The name is a combination of the old village of ''Werven''/''Warven'' and ''Ort'' (place). Werven originally was located south of Warverort and depicted on maps of the island Büsum as early as 1559. It sank completely during devastating storm tides in 1717 and 1718. The ''Wehl'' behind the dike in Warwerort serves as another flood reminder. It formed where the sea washed out the soil after a dike break and left a brackish lake on the landside of the dike. Warwerort's harbor became dysfunctional when the dike around the Speicherkoog (build between 1969 and 1978) to the southeast blocked its access to the North Sea The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium.

Bernhard Nocht Institute For Tropical Medicine
Bernhard Nocht Institute for Tropical Medicine (Bernhard-Nocht-Institut für Tropenmedizin) (BNITM) in Hamburg is Germany's largest institution for tropical medicine, with a workforce of about 250 people in Hamburg. It is member of the Leibniz-Association. History The cholera epidemic of the year 1892 claimed thousands of lives and prompted the Senate and Parliament of the City of Hamburg to reform the health care system. The Tropical Medicine Institute was founded with the support of the Imperial Government to research ship and tropical diseases and to train ship and colonial physicians. In 1893, the naval physician was introduced to the newly created position of port physician. For the medical care of seamen suffering from internal diseases, he was also given a department in the St. Georg General Hospital. Contrary to the plans of the bacteriologist Robert Koch, Nocht established Hamburg in 1899 as the location for an institute for the research of tropical diseases, since "d ...

Infusoria
Infusoria are minute freshwater life forms including ciliates, euglenoids, protozoa, unicellular algae and small invertebrates. Some authors (e.g., Bütschli) used the term as a synonym for Ciliophora. In modern formal classifications, the term is considered obsolete; the microorganisms previously included in the Infusoria are mostly assigned to the kingdom Protista. Aquarium use Infusoria are used by owners of aquaria to feed fish fry; because of its small size it can be used to rear newly hatched fry of many common aquarium species. Many home aquaria are unable to naturally supply sufficient infusoria for fish-rearing, so hobbyists may create and maintain their own supply cultures or use one of the many commercial cultures available.Sharpe, Shirlie (December 22, 2018)"How to Culture Your Own Infusoria at Home" The Spruce Pets. Retrieved August 28, 2019. Infusoria can be cultured by soaking any decomposing vegetative matter such as papaya skin in a jar of aged (i.e., chlorine-fr ...

Friedrich Dahl
Karl Friedrich Theodor Dahl (June 24, 1856 in Rosenhofer Brök north of Dahme, Holstein – June 29, 1929 in Greifswald) was a German zoologist, and in particular an arachnologist. The son of a farmer, Dahl studied at the universities of Leipzig, Freiburg, Berlin and Kiel. His dissertation (1884) was "''Beiträge zur Kenntnis des Baus und der Funktion der Insektenbeine''". He became a '' Privatdozent'' in 1887; with a habilitation thesis "''Ueber die Cytheriden der westlichen Ostsee''". Around this time he traveled to the Baltic states and (1896–1897) to the Bismarck Archipelago near New Guinea. He was also interested in biogeography. On April 1, 1898 Dahl became curator of arachnids at the ''Museum für Naturkunde'' in Berlin, where he worked under his former teacher, the then museum director Karl Möbius. Dahl remained in Berlin until he retired, and his type collection is held in that museum. Although he described in many animal groups, Dahl concentrated on spider ...
