Théophile Seyrig
François Gustave Théophile Seyrig (19 February 1843 to 5 July 1923) was a German engineer, best known for designing bridges. On 6 October 1868, he founded ''Eiffel and Company'' with Gustave Eiffel. Seyrig contributed to the Eiffel and Company project to build the Maria Pia Bridge in Porto, Portugal, which was finished in 1877. Seyrig presented a paper on the bridge to the Société des Ingénieurs Civils in 1878. Later he worked for the Belgian firm Société Willebroeck in Brussels, and won the competition to build the Dom LuÃs I Bridge (also in Porto), beating the Eiffel proposal. He began construction in 1881 and the bridge was finished in 1886. Works * Maria Pia Bridge * Dom LuÃs I Bridge * Neuvial Viaduct * Rouzat Viaduct File:PonteMariaPia.jpg , Maria Pia Bridge (1877).

Berlin
Berlin is Capital of Germany, the capital and largest city of Germany, both by area and List of cities in Germany by population, by population. Its more than 3.85 million inhabitants make it the European Union's List of cities in the European Union by population within city limits, most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, Brexit, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the List of German states by area, third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin/Brandenburg Metropolitan Region, Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan reg ...

Germany
Germany, officially the Federal Republic of Germany (FRG),, is a country in Central Europe. It is the most populous member state of the European Union. Germany lies between the Baltic and North Sea to the north and the Alps to the south. Its 16 constituent states have a total population of over 84 million in an area of . It borders Denmark to the north, Poland and Czechia to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in what is now Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
École Centrale Paris
École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name ''École Centrale des Arts et Manufactures''. In 2015, École Centrale Paris merged with Supélec to form CentraleSupélec, a constituent college of the University of Paris-Saclay. Founded in 1829, it was among the most prestigious and selective grandes écoles. Rooted in rich entrepreneurial tradition since the industrial revolution era, it served as the cradle for top-level engineers and executives who continue to constitute a major part of the industry leadership in France. Since the 19th century, its model of education for training generalist engineers inspired the establishment of several engineering institutes around the world, such as the École Polytechnique Fédérale de Lausanne in Switzerland, Faculté polytechnique de Mons in Belgium, as well as other member schools of the Ecole Centrales Group alliance ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year Bachelor of Engineering, bachelor's degree in an engineering discipline, or in some jurisdictions, a Master of Engineering, master's degree in an engineering discipline plus ...

Bridge
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Gustave Eiffel
Alexandre Gustave Eiffel (born Bonickhausen dit Eiffel; ; ; 15 December 1832 – 27 December 1923) was a French civil engineer. A graduate of École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit Viaduct. He is best known for the world-famous Eiffel Tower, designed by his company and built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields. Early life Alexandre Gustave Eiffel was born in France, in the Côte-d'Or, the first child of Catherine-Mélanie (née Moneuse) and Alexandre Bonickhausen dit Eiffel. He was a descendant of Marguerite Frédérique (née Lideriz) and Jean-René Bönickhausen and who had emigrated from the German town of Marmagen and settled in Paris at the beginni ...

Maria Pia Bridge
The Maria Pia Bridge (in Portuguese ''Ponte de D. Maria Pia'', commonly known as ''Ponte de Dona Maria Pia'') is a railway bridge built in 1877, and attributed to Gustave Eiffel, situated over the Portuguese northern municipalities of Porto and Vila Nova de Gaia. Part of the Linha Norte system of the national railway, the wrought iron, double-hinged, crescent arch spans , over the Douro River. At the time of its construction, it was the longest single-arch span in the world; today, it is no longer used for rail transport and was replaced by a modern structure in 1991. It is often confused with the D. LuÃs Bridge, which was built nine years later and is located to the west, but resembles the structure, albeit with two decks. History In 1875, the Royal Portuguese Railway Company announced a competition for a bridge to carry the Lisbon to Porto railway across the river Douro. This was very technically demanding: the river was fast-flowing, its depth could be as much as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dom LuÃs I Bridge
The Dom LuÃs I Bridge ( pt, Ponte de Dom LuÃs I), or LuÃs I Bridge, is a double-deck metal arch bridge that spans the River Douro between the cities of Porto and Vila Nova de Gaia in Portugal. At its construction, its span was the longest of its type in the world. It has been confused with the nearby Maria Pia Bridge, a railway bridge that was built 9 years earlier (and is located to the east), which is similar in aspect to the LuÃs I bridge. History In 1879, Gustave Eiffel presented a project to construct a new bridge over the Douro, with a high single deck in order to facilitate ship navigation. This project was rejected due to dramatic growth of the urban population, which required a re-thinking of the limits of a single-deck platform. A competition was initiated in November 1880, in order to construct a double-deck metal bridge, which included projects by Compagnie de Fives-Lille, Cail & C., Schneider & Co., Gustave Eiffel, Lecoq & Co., Société de Braine-le-Co ...
