Ewald Heinrich Rübsaamen
Ewald Heinrich Rübsaamen (20 May 1857, Haardt – 17 March 1919, Metternich) was a German teacher, artist, and amateur entomologist who studied gall forming insects, especially the gall midges (Cecidomyiidae), and worked on pest control in grapes, most importantly on ''Phylloxera''. Rübsaamen was the second son of Johann Franz and Emilie Mathilde Johanne. His father manufactured precision mechanical instruments for mines. After school at Weidenau, Ewald entered the gymnasium in Siegen Siegen () is a city in Germany, in the south Westphalian part of North Rhine-Westphalia North Rhine-Westphalia (german: Nordrhein-Westfalen, ; li, Noordrien-Wesfale ; nds, Noordrhien-Westfalen; ksh, Noodrhing-Wäßßfaale), commonly sho ... and in 1875 went to study mathematics at the Technical College in Karlsruhe.

Cecidomyiidae
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A DNA barcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have yet ...

Phylloxera
Grape phylloxera is an insect pest of commercial grapevines worldwide, originally native to eastern North America. Grape phylloxera (''Daktulosphaira vitifoliae'' (Fitch 1855) belong to the family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as ''Phylloxera vastatrix''; equated to the previously described ''Daktulosphaera vitifoliae'', ''Phylloxera vitifoliae''. The insect is commonly just called phylloxera (; from grc, φύλλον, leaf, and , dry). These almost microscopic, pale yellow sap-sucking insects, related to aphids, feed on the roots and leaves of grapevines (depending on the phylloxera genetic strain). On ''Vitis vinifera'', the resulting deformations on roots ("nodosities" and "tuberosities") and secondary fungal infections can girdle roots, gradually cutting off the flow of nutrients and water to the vine.Wine & Spirits Education Trust ''"Wine and Spirits: Understanding Wine Quality"'' pgs 2-5, Second Revised Edition (2012), Lo ...

Karl Möbius
Karl August Möbius (7 February 1825 in Eilenburg – 26 April 1908 in Berlin) was a German zoologist who was a pioneer in the field of ecology and a former director of the Museum für Naturkunde in Berlin. Early life Möbius was born in Eilenburg in Saxony. At the age of four he attended primary school at the Bergschule Eilenburg, and at the age of 12 he was sent by his father to train as a teacher. In 1844 he passed the exams with distinction and began working as teacher in Seesen, on the northwest edge of the Harz mountain range. In 1849, and encouraged by Alexander von Humboldt, he began studying natural science and philosophy at Natural History Museum of Berlin. After he graduated, he taught from 1853 to 1868 zoology, botany, mineralogy, geography, physics, and chemistry at the Gelehrtenschule des Johanneums in Hamburg. Oysters and ecology In 1863 he opened the first German sea water aquarium, in Hamburg. In 1868, shortly after passing his doctoral examination at the ...

Natural History Museum, Berlin
The Natural History Museum (german: Museum für Naturkunde) is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major museums in Germany alongside ''Naturmuseum Senckenberg'' in Frankfurt and ''Museum Koenig'' in Bonn. The museum houses more than 30 million zoological, paleontological, and mineralogical specimens, including more than ten thousand type specimens. It is famous for two exhibits: the largest mounted dinosaur in the world (a ''Giraffatitan'' skeleton), and a well-preserved specimen of the earliest known bird, '' Archaeopteryx''. The museum's mineral collections date back to the Prussian Academy of Sciences of 1700. Important historic zoological specimens include those recovered by the German deep-sea Valdiva expedition (1898–99), the German Southpolar Expedition (1901–03), and the German Sunda Expedition (1929–31).

Jean-Jacques Kieffer
Jean-Jacques Kieffer (1857 in Guinkirchen – 1925 in Bitche) was a French naturalist and entomologist who specialised in the study of parasitic insects. Educated as a priest, Kieffer taught natural science in Bitche, Lorraine while working on the description and classification of insects. His work and publications later became a predominant source of description and classification for entomologists in the early 20th century, in particular with regard to parasitoid wasps, midges, and mosquitos. He collaborated with the English entomologist Peter Cameron. Kieffer received an honorary Doctor honoris causa degree from the University of Strasbourg in 1904.
