Document 2: Garabit viaduct: The Garabit Viaduct ("Viaduc de Garabit" in French) is a railway arch bridge spanning the River Truyère near Ruynes-en-Margeride (), Cantal, France, in the mountainous Massif Central region. The bridge was constructed between 1882 and 1884 by Gustave Eiffel, with structural engineering by Maurice Koechlin, and was opened in 1885. It is 565 m in length and has a principal arch of 165 m span.
Document 3: Jiujiang Yangtze River Bridge: The Jiujiang Yangtze River Bridge is a combined road-rail bridge over the Yangtze River near the city of Jiujiang, Jiangxi Province in eastern China. It links Xunyang District of Jiujiang, south of the river, with Xiaochi Town in Huangmei County, Hubei Province, to the north. The central section of the bridge uses a combined arch and truss structure and the bridge is one of the longest continuous truss bridges in the world, with a longest span of 216 m and a total truss length of 1314 m =3x162+180+216+180+2x126. The double deck bridge carries four vehicular lanes and two sidewalks on the top deck and two railway tracks on the bottom deck.
Document 4: Léon Foucault: Jean Bernard Léon Foucault (] ; 18 September 1819 – 11 February 1868) was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of the Earth's rotation. He also made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
Document 5: Railway Bridge, Kaunas: Railway Bridge in Kaunas crosses Nemunas river to connect Central Kaunas and lower Freda of Aleksotas district. Because of its green paint, it is often called "Green" (Lithuanian: "Žaliasis" ). Construction of the bridge started in 1859 and ended in 1862. The exploitation of the bridge started on the 4 February 1862. Together with central Kaunas Railway Station and Kaunas Railway Tunnel, it forms an important Kaunas railway hub in Lithuania. However, during World War I parts of the bridge were destroyed, but soon afterwards were rebuilt as well as the standard gauge was laid by Germans during World War I. Paul von Hindenburg was among the guests who participated in the opening ceremony of the reconstructed bridge. During World War II, the bridge was blown up several times, but was rebuilt later. Kaunas Railway Bridge was included into the Registry of Immovable Cultural Heritage Sites of the Republic of Lithuania in 1996.
Document 6: Octave Chanute: Octave Chanute (February 18, 1832, Paris – November 23, 1910, Chicago, Illinois) was an American civil engineer and aviation pioneer, born in France. He provided many budding enthusiasts, including the Wright brothers, with help and advice, and helped to publicize their flying experiments. At his death he was hailed as the father of aviation and the heavier-than-air flying machine.
Document 7: Gustave Eiffel: Alexandre Gustave Eiffel (born Bönickhausen; ; ] ; 25 December 1832 – 27 December 1923) was a French civil engineer and architect. A graduate of École Centrale Paris, 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, 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.
Document 8: Émile Nouguier: Émile Nouguier (17 February 1840 – 23 November 1897) was a French civil engineer and architect. He is famous for co-designing the Eiffel Tower, built 1887–1889 for the 1889 Universal Exposition in Paris, France, the Garabit viaduct, the highest in the world at the time, near Ruynes-en-Margeride, Cantal, France, and the Faidherbe Bridge over the Sénégal River in Senegal.
Document 9: London Bridge – Greenwich Railway Viaduct: The London Bridge – Greenwich Railway Viaduct consists of a series of nineteen brick railway viaducts linked by road bridges between London Bridge railway station and Deptford Creek, which together make a single structure 3.45 mi in length. The structure carries the former London and Greenwich Railway line and consists of 851 semi-circular arches and 27 skew arches or road bridges. It is the longest run of arches in Britain, It is also one of the oldest railway viaducts in the world, and the earliest example of an entirely elevated railway line. It was built between 1834 and 1836. The original viaduct had been widened for 1.95 mi of its length between Corbett's Lane and London Bridge on the south side to accommodate the trains of the London and Croydon Railway and London and Brighton Railway, in 1842 and also for 2.65 mi on the north side to accommodate the South Eastern Railway main line in 1850. It is a Grade II listed structure.
Document 10: John Alexander Low Waddell: John Alexander Low Waddell (1854 – March 3, 1938, often shortened to J.A.L. Waddell and sometimes known as John Alexander Waddell) was an American civil engineer and prolific bridge designer, with more than a thousand structures to his credit in the United States, Canada, as well as Mexico, Russia, China, Japan, and New Zealand. Waddell’s work set standards for elevated railroad systems and helped develop materials suitable for large span bridges. His most important contribution was the development of the steam-powered high-lift bridge. His design was first used in 1893 for Chicago's South Halsted Street Lift-Bridge over the Chicago River; he went on to design more than 100 other movable bridges, and the company he founded continues to make movable bridges of various types. Waddell was a widely respected writer on bridge design, and an advocate of quality training of engineers. Many of Waddell's surviving bridges are now considered historic landmarks.
Document 11: George Washington Gale Ferris Jr.: George Washington Gale Ferris Jr. (February 14, 1859 – November 22, 1896) was an American engineer. He is mostly known for creating the original Ferris Wheel for the 1893 Chicago World's Columbian Exposition.
Document 12: Conservation-restoration of the Statue of Liberty: The conservation-restoration of the Statue of Liberty spanned from 1984 to 1986. The Statue of Liberty ("Liberty Enlightening the World" by Frédéric Auguste Bartholdi) is a colossal monument on Liberty Island in New York Harbor and is a part of the Statue of Liberty National Monument. Much of the restoration effort was based on unprecedented restorative methods, owing largely to the fact that metallurgical repair work on such a scale had never been attempted before. Many professional scientists and engineers, government organizations and various consultants were called in to evaluate and deal with the various problems and tasks facing the restoration effort.
Document 13: Germain Sommeiller: Germain Sommeiller (February 15, 1815 – July 11, 1871) was a civil engineer from Savoy. He directed the construction of the Fréjus Rail Tunnel between France and Italy, also known as the Mont Cenis Tunnel. This was the first of a series of major tunnels built in the late 19th century to connect northern and southern Europe through the Alps. Sommeiller pioneered the use of pneumatic drilling and dynamite to achieve record-breaking excavation speeds. This 12.8-km tunnel was completed on December 26, 1870, 11 years ahead of schedule. It remained the longest tunnel in the world until the opening of the Gotthard Rail Tunnel in 1882.
Document 14: Louis Le Chatelier: Louis Le Chatelier (20 February 1815 – 10 November 1873) was a French chemist and industrialist who developed a method for producing aluminium from bauxite in 1855. His son was the well known chemist Henri Louis Le Chatelier. His name is inscribed on the Eiffel tower.
Document 15: Niagara Falls Suspension Bridge: The Niagara Falls Suspension Bridge, which stood from 1855 to 1897 across the Niagara River, was the world's first working railway suspension bridge. It spanned 825 ft and stood 2.5 mi downstream of Niagara Falls, where it connected Niagara Falls, Ontario, to Niagara Falls, New York. Trains used the upper of its two decks, pedestrians and carriages the lower. The brainchild of Canadian politicians, the bridge was built by one American and one Canadian company. It was most commonly called the Suspension Bridge; other names included Niagara Railway Suspension Bridge, Niagara Suspension Bridge, and its official American name, the International Suspension Bridge.
