Østervold Observatory
Østervold Observatory (or Copenhagen University Observatory; da, Københavns Universitet Astronomisk Observatorium) is a former astronomical observatory (IAU code 035) in Copenhagen, Denmark owned and operated by the University of Copenhagen (Københavns Universitet). It opened in 1861 as a replacement for the University's old observatory at Rundetårn. History The first astronomical observatory operated by the University of Copenhagen was Rundetårn. It had been inaugurated in 1642 as a replacement for Tycho Brahe's Stjerneborg, but during the early 19th century had become outdated as astronomical instruments grew bigger and bigger while the tower could not be expanded. In the same time, light pollution from the surrounding city as well as vibrations caused by the still increasing traffic in the streets below had made the observations inaccurate. In 1861 the observatory was moved to Østervold, where a new observatory was constructed on the old bastioned fortifications of ...

People From Randers Municipality
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Siemens & Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

Aktieselskab
''Aktieselskab'' (; Abbreviation, abbr.: A/S, or a/s, Unicode ; literally meaning: "stock company") is the Denmark, Danish name for a stock-based corporation. An ''aktieselskab'' may be either publicly traded or private. Liability The shareholders of an ''aktieselskab'' are not liable for the debts of the company. This can be used to protect the assets of the company against creditors by forming a group of companies. If an A/S is owned by a holding company (typically another A/S), the profit from the production company can be transferred to the holding company. Since there is no liability for the owners of an A/S, creditors from the production company will not be able to claim the profit in case of bankruptcy. Professional creditors, such as banks, protect themselves from this by demanding that the holding company guarantees the debts of the production company. Formation of an ''aktieselskab'' The formation of an ''aktieselskab'' requires a number of steps, including the followi ...

Rasmus Malling-Hansen
Hans Rasmus Johan Malling-Hansen (5 September 1835 – 27 September 1890) was a Danish inventor, minister and principal at the Royal Institute for the Deaf. He is famous for inventing the first commercially produced typewriter. Early career Malling-Hansen was born in Hunseby, Lolland in 1835. He invented the Hansen Writing Ball in 1865. In 1874 he patented a new model jointly in which the cylinder was replaced by a flat carriage on which the paper was fastened. In 1875, the original design of the writing ball was replaced with a mechanical frame. With this model, he found a mechanical solution for the movement of the paper, dispensing with the battery. While the writing ball was sold in many countries in Europe, it was an expensive product and achieved little commercial success. The writing ball was successful at different exhibitions, Malling-Hansen and Halll, received the first prize medal at a large industrial exhibition in Copenhagen in 1872, and at the world exhibi ...
