John A. Roebling's Sons Company
John Augustus Roebling (born Johann August Röbling; June 12, 1806 – July 22, 1869) was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark. Education John Röbling was born to Friederike Dorothea Röbling (née Muelleren) and Christoph Polykarpus Röbling. Recognizing his intelligence at a young age, Roebling's mother arranged for him to be tutored in mathematics and science at Erfurt by Ephraim Salomon Unger. He went to Erfurt when he was 15. In 1824 he passed his Surveyor's examination and returned home for a year.

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prussia
Prussia, , Old Prussian: ''Prūsa'' or ''Prūsija'' was a German state on the southeast coast of the Baltic Sea. It formed the German Empire under Prussian rule when it united the German states in 1871. It was ''de facto'' dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and ''de jure'' by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. In 1871, Prussian Minister-President Otto von Bismarck united most German principalities into the German Empire under his leadership, although this was considered to be a "Lesser Germany" because Austria and Switzerland were not included. In November 1918, the monarchies were abolished and the nobility lost its political power during the Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napoleonic Wars
The Napoleonic Wars (1803–1815) were a series of major global conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European states formed into various coalitions.

The wars stemmed from the unresolved disputes associated with the French Revolution and the French Revolutionary Wars consisting of the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). The Napoleonic Wars are often described as five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1803–1806), the Fourth (1806–1807), the Fifth (1809), the Sixth (1813–1814), and the Seventh (1815) plus the Peninsular War (1807–1814) and the French invasion of Russia (1812).

Utopia
A utopia ( ) typically describes an imaginary community or society that possesses highly desirable or nearly perfect qualities for its members. It was coined by Sir Thomas More for his 1516 book ''Utopia (book), Utopia'', describing a fictional island society in the New World. However, it may also denote an intentional community. In common parlance, the word or its adjectival form may be used synonymously with "impossible", "far-fetched" or "deluded". Hypothetical utopias focus on—amongst other things—equality, in such categories as economics, government and justice, with the method and structure of proposed implementation varying based on ideology. Lyman Tower Sargent argues that the nature of a utopia is inherently contradictory because societies are not homogeneous and have desires which conflict and therefore cannot simultaneously be satisfied. To quote: The opposite of a utopia is a dystopia or cacotopia. Utopian and dystopian fiction has become a popular literary catego ...

Johann Adolphus Etzler
John Adolphus Etzler (1791–1846?) was a German engineer and inventor who immigrated to the United States in 1831 with a vision of creating a technological utopia. He was traveling with a group from Prussia, who included younger engineers John A. Roebling and his brother Carl. Because of disagreements, the group broke up. Etzler and most of the group first settled near Pittsburgh, Pennsylvania. In the early 1840s Etzler and several dozen of his followers moved to the tropics, to set up utopian communities to use his inventions in Venezuela and Trinidad. He believed his inventions could work off natural forces and avoid human labor. Their efforts failed and many people died. Etzler survived but disappeared from the record. Time in the US In 1833 in Pittsburgh, Etzler published his best-known work, a prospectus titled ''The Paradise within the Reach of all Men''. It outlined detailed, visionary plans to harness the energy of wind, water and sun to benefit mankind. This followed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
