Charles De Geer (1747–1805)
Charles De Geer (30 January 1720 – 7 March 1778) was an entomologist, industrialist, civil servant and book collector. He is sometimes referred to as Charles the Entomologist, to distinguish him from other relatives with the same name. Charles De Geer came from a prominent Swedish-Dutch family. Born in Sweden, he spent most of his childhood and youth in the Dutch Republic. At the age of 18 he moved back to Sweden and would spend the rest of his life there. Upon his return to Sweden, he took over the management of the ironworks of Lövstabruk. He was a successful businessman and with time became one of the richest men in Sweden, head of an early industry employing around 3,000 people. He had a successful civic career, became Marshal of the Court and was elevated to the rank of ''friherre'' (baron) in 1773. De Geer had developed an interest in natural history and particularly entomology when he was still young. After his return to Sweden, his interest transformed into a seriou ...

Gustaf Lundberg
Gustaf Lundberg (17 August 1695 – 18 March 1786) was a Swedish rococo pastelist and portrait painter. He trained and worked in Paris and later was appointed court portrait painter in Stockholm. Biography Lundberg was born in Stockholm, Sweden, son of royal chef Gustaf Lundberg and his wife Sabina Richter, whose family included successful artists. Orphaned at an early age, he was raised by his grandfather, Fredrik Richter, who was a goldsmith. Lundberg was later apprenticed to German-Swedish painter David von Krafft (1655–1724) in 1712. In 1717, Lundberg traveled to Paris, where he studied with Hyacinthe Rigaud (1659–1743), Nicolas de Largillière (1656–1746) and Jean-François de Troy (1679–1752). The determining influence was the Venetian painting, Venetian painter Rosalba Carriera (1675–1757), who lived in Paris from 1720 to 1721. Afterwards, Lundberg established himself as one of the leading portrait painters in Paris. He painted Louis XV and his Queen Marie Leszcz ...

Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female carpel, stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of Aculeata, aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, Phalangeriformes, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination s ...

Joseph Pitton De Tournefort
Joseph Pitton de Tournefort (5 June 165628 December 1708) was a French botanist, notable as the first to make a clear definition of the concept of genus for plants. Botanist Charles Plumier was his pupil and accompanied him on his voyages. Life Tournefort was born in Aix-en-Provence and studied at the Jesuit convent there. It was intended that he enter the Church, but the death of his father allowed him to follow his interest in botany. After two years collecting, he studied medicine at Montpellier, but was appointed professor of botany at the Jardin des Plantes in Paris in 1683. During this time he travelled through Western Europe, particularly the Pyrenees, where he made extensive collections. Between 1700 and 1702 he travelled through the islands of Greece and visited Constantinople, the borders of the Black Sea, Armenia, and Georgia, collecting plants and undertaking other types of observations. He was accompanied by the German botanist Andreas Gundelsheimer (1668� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, jellyfish, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis (" hemimetaboly"), or no metamorphosis (" ametaboly"). Generally organisms with a larval stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. Etymology The word ''metamorphosis'' derives from Ancient Greek , "transformation, transforming", from ('), "after" and ('), "form". Hormonal control In insects, growth and metamorphosis are controlled by hormones synthesized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombyx Mori
''Bombyx mori'', commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of '' Bombyx mandarina'', the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the Osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths, which are other species of ''Bombyx'', are not as commercially viable in the production of silk. Sericulture, the practice of breeding silkworms for the production of raw silk, has existed for at least 5,000 years in China, whence it spread to India, Korea, Nepal, Japan, and then the West. The conventional process of sericulture kills the silkworm in the pupal stage. The domestic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobiliary Particle
A nobiliary particle is a type of onomastic particle used in a surname or family name in many Western cultures to signal the nobility of a family. The particle used varies depending on the country, language and period of time. In some languages, it is the same as a regular prepositional particle that was used in the creation of many surnames. In some countries, it became customary to distinguish the nobiliary particle from the regular one by a different spelling, although in other countries these conventions did not arise, occasionally resulting in ambiguity. The nobiliary particle can often be omitted in everyday speech or certain contexts. Denmark and Norway In Denmark and Norway, there is a distinction between (1) nobiliary particles in family names and (2) prepositions denoting an individual person's place of residence. Nobiliary particles like af, von, and de (English: ''of'') are integrated parts of family names. The use of particles was not a particular privilege for ...

Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could poten ...

Inoculation
Inoculation is the act of implanting a pathogen or other microbe or virus into a person or other organism. It is a method of artificially inducing immunity against various infectious diseases. The term "inoculation" is also used more generally to refer to intentionally depositing microbes into any growth medium, as into a Petri dish used to culture the microbe, or into food ingredients for making cultured foods such as yoghurt and fermented beverages such as beer and wine. This article is primarily about the use of inoculation for producing immunity against infection. Inoculation has been used to eradicate smallpox and to markedly reduce other infectious diseases such as polio. Although the terms "inoculation", "vaccination", and "immunization" are often used interchangeably, there are important differences. Inoculation is the act of implanting a pathogen or microbe into a person or other recipient; vaccination is the act of implanting or giving someone a vaccine specifical ...

De Geer Family
The De Geer family (, ; also: De Geer van Jutphaas and De Geer van Oudegein) is a prominent industrial family of Walloon origin that belongs to the Swedish and Dutch nobility. History The name derives from the town of Geer near Liège (in present-day Belgium). The oldest known ancestor, Lambier de Geer, lord of Gaillarmont, died in 1399 in Liège, then part of the Prince-Bishopric of Liège. His descendant Louys de Geer (1535–1602) moved from Liège to Aachen and later to Dordrecht in the Dutch Republic for religious reasons. Subsequent generations became notable in Sweden and the Netherlands from the early 17th century, mainly centered on the iron-foundry company town Finspång, but often extending to science, art and national politics. The larger, Swedish branch of the family retained its contacts with the Netherlands. Some of them hold the title of baron. Both branches are still in existence.
