Ernst Werner Von Siemens
Ernst Werner Siemens (von Siemens from 1888; ; ; 13 December 1816 – 6 December 1892) was a German electrical engineer, inventor and industrialist. Siemens's name has been adopted as the SI unit of electrical conductance, the siemens. He founded the electrical and telecommunications conglomerate Siemens and invented the electric tram, trolley bus, electric locomotive and electric elevator. His dynamo laid the foundation for the modern age of electricity and he was involved in the development of the electric car. Biography Early years Ernst Werner Siemens was born in Lenthe, today part of Gehrden, near Hannover, in the Kingdom of Hanover in the German Confederation, the third child (of fourteen) of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839). His father was a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. Carl Heinrich von Siemens and Carl Wilhelm Siemens were his br ...

Dynamo
"Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator. Dynamos employed electromagnets for self-starting by using residual magnetic field left in the iron cores of electromagnets (i.e. field coils). If dynamo were never run before it was usual to use a separate battery to excite or ''flash the field'' of the electromagnets to enable self-starting. Dynamos were the first practical electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler and more reliable alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using rectifiers (such as va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Schleswig War
The First Schleswig War (), also known as the Schleswig-Holstein uprising () and the Three Years' War (), was a military conflict in southern Denmark and northern Germany rooted in the Schleswig–Holstein question: who should control the Duchies of Schleswig, Holstein and Lauenburg, which at the time were ruled by the king of Denmark in a personal union. Ultimately, the Danish side proved victorious with the diplomatic support of the great powers, especially Britain and Russia, since the duchies were close to an important Baltic seaway connecting both powers. While Schleswig had been predominantly Danish with a German elite concentrated in the cities and estates, modernization brought extensive German influence. German became the language of administration, education, and the church, creating an environment in which it was omnipresent and speaking Danish offered no advantages. Due to top-down pressure, many Danish South Schleswigers gradually adopted German in their dai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiel
Kiel ( ; ) is the capital and most populous city in the northern Germany, German state of Schleswig-Holstein. With a population of around 250,000, it is Germany's largest city on the Baltic Sea. It is located on the Kieler Förde inlet of the Bay of Kiel and lies in the southeast of the Jutland Peninsula, on the mouth of the Schwentine River, approximately northeast of Hamburg.

Most of Kiel is part of Holstein. The boroughs north of the Schwentine also belong to Wagria, while those north of the Kiel Canal are historically part of Southern Schleswig. Kiel is one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel mutiny, Kiel Mutiny, when sailors re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian Military Academy
The Prussian Staff College, also Prussian War College () was the highest military facility of the Kingdom of Prussia to educate, train, and develop general staff officers. Location It originated with the ''Akademie für junge Offiziere der Infanterie und Kavallerie'' (Academy for young officers of the infantry and cavalry) in 1801, later becoming known as the Allgemeine Kriegsschule (General War-School). It was officially re-founded by Gerhard von Scharnhorst in Berlin on October 15, 1810 as one of three officer colleges. Its building on Unter den Linden (1845/25), Berlin, was designed by Karl Friedrich Schinkel. Graduation Graduating from the ''Staff College'' was a prerequisite for appointment to the ''Prussian General Staff'' (later the German General Staff). Carl von Clausewitz enrolled as one of its first students in 1801 (before it was renamed), while other attendees included Field Marshals von Steinmetz, von Moltke, and von Blumenthal in the 1820s and 1830s.

Bauakademie
The Bauakademie (Building Academy, also known as the ''Schinkelsche Bauakademie'') in Berlin, Germany, was a higher education institution for the art of building to train master builders. Founded on 18 March 1799 by King Frederick William III, the institution originated from the construction department of the Academy of Fine Arts and Mechanical Sciences (from 1704), which emphasized the aesthetic elements of the art of building while ignoring the technical. Thus, the governmental Upper Building Department ("UBD") decided to establish an entirely new building educational institution named "Bauakademie". In 1801, the institution was incorporated into the UBD. An iconic building in the history of engineering and architecture for its red brick facade, the Bauakademie was designed by German architect Karl Friedrich Schinkel between 1832 and 1836. Its red brick façade was considered an early basis for modernist architectural styles. In 1945, the building was destroyed during W ...

Siemens Family
The ''Siemens family'' is the name of a German nobility, German noble family, family of technology and telecommunications industrialists, whose members were founders and to the present day the largest shareholders of Siemens AG. The family had a wealth of over €8 billion, that made them the 5th richest family in Germany, according to Handelsblatt History Origin The Siemens family was first documented in 1384 with Henning Symons, a farmer of the Free imperial city of Goslar in Lower Saxony, Germany.

Tenant Farmer
A tenant farmer is a farmer or farmworker who resides and works on land owned by a landlord, while tenant farming is an agricultural production system in which landowners contribute their land and often a measure of operating capital and management, while tenant farmers contribute their labor along with at times varying amounts of capital and management. Depending on the terms of their contract, tenants may make payments to the owner either of a fixed portion of the product, in cash or in a combination. The rights the tenant has over the land, the form, and measures of payment vary across systems (geographically and chronologically). In some systems, the tenant could be evicted at whim ( tenancy at will); in others, the landowner and tenant sign a contract for a fixed number of years ( tenancy for years or indenture). In most developed countries today, at least some restrictions are placed on the rights of landlords to evict tenants under normal circumstances. England and ...
