Carl Gustav Calwer
Carl Gustav Calwer (11 November 1821, Stuttgart — 19 August 1874, Mineralbad Berg) was a German entomologist who specialised in Coleoptera. He wrote initially with the Stuttgart professor Dr Gustav Jäger ''Käferbuch, Naturgeschichte der Käfer Europas'' published by Julius Hoffmann, Stuttgart a 666-page work with 50 lithographic plates all but two in colour. This very popular work was successively reprinted until 1916. Many of the fine plates were reused in Georgij Georgiewitsch Jacobson Georgiy Georgiyevich Jacobson also known as Jakobson ( ru , Георгий Георгиевич Якобсон, 1871 – 23 November 1926) was a pioneering Russian entomologist, known especially for his 900-page book on beetles. Biography ...'s 1905 ''Beetles of Russia'', enabling Jacobson to focus on illustrating previously undescribed species. References *Anonym 1874, alwer, C. G.''Nachr. bl. dtsch. malacol.

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ...

Gustav Jäger (naturalist)
Gustav Jäger (June 23, 1832 – May 13, 1917) was a German naturalist and hygienist. Biography He was born at the historic Pfarrhaus in the village of Bürg, Neuenstadt am Kocher in Württemberg. After studying medicine at Tübingen, he became a teacher of zoology in Vienna. In 1868, he was appointed professor of zoology at the academy of Hohenheim, and subsequently he became teacher of zoology and anthropology at Stuttgart Polytechnic and professor of physiology at the Veterinary School. In 1884, he abandoned teaching and started practice as a physician in Stuttgart. He wrote various works on biological subjects, including ''Die Darwinsche Theorie und ihre Stellung zu Moral und Religion'' (1869), and ''Lehrbuch der allgemeinen Zoologie'' (1871–1878). Jäger was an early supporter of Darwinism. In 1876, he suggested a hypothesis in explanation of heredity, resembling the germ plasm theory subsequently elaborated by August Weismann, to the effect that the germinal protoplasm ...

Lithography
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plat ...

Georgij Georgiewitsch Jacobson
Georgiy Georgiyevich Jacobson also known as Jakobson ( ru , Георгий Георгиевич Якобсон, 1871 – 23 November 1926) was a pioneering Russian entomologist, known especially for his 900-page book on beetles. Biography Jacobson was born in St Petersburg, and in 1893 he graduated from St Petersburg University's Physics and Mathematics faculty. He was a zoologist at the Zoological Museum of the Russian Academy of Sciences. He was posted to different parts of Russia to study its insects. He published papers mainly on the systematics and zoogeography of Chrysomelidae beetles. Beetles Jacobson's ''Beetles'' was first published in 1905 by Devriena, St Petersburg. The eleventh and last edition appeared in 1915. Many of the fine colour plates were based on Carl Gustav Calwer's ''Kaeferbuch'', with updates to the names of some of the beetles. This saving of effort on illustration allowed Jacobson to focus on illustrating species of beetle that had never been i ...
