Anghel Saligny


Anghel Saligny was a Romanian engineer, most famous for designing the Fetești-Cernavodă railway bridge over the Danube, the longest bridge in Europe at that time. He also designed the storage facilities in Constanța seaport, one of the earliest examples of reinforced concrete architecture in Europe.

Biography

Saligny was born in Șerbănești, Tecuci County. His father, Alfred Saligny, an educator of French descent, was an immigrant to Moldavia, coming from Prussia. He started his studies at the boarding school founded by his father in Focșani, then went on to high school, initially also in Focșani and then in Potsdam, Germany. He pursued engineering studies at the Royal Technical Higher School in Charlottenburg, and then contributed to the construction of railways in Saxony. He was a founding member of the Bucharest Polytechnic Society and was even appointed Minister of Public Works. In 1892, he was elected a member of the Romanian Academy, and he served as its president between 1907 and 1910.
Anghel Saligny's brother Alfons Oscar Saligny was a chemist and educator who was also elected a member of the Romanian Academy.

Works

In all of his works, new elements are to be found. Some of them were considered great technological advances at the time.
Saligny drew the plans for the Adjud–Târgu Ocna railway, which included the first mixed-use bridges in Romania. He was also involved in the construction of numerous other metallic bridges, such as the one at Cosmești over the Siret river, which measured 430 m in length.
Between 1884 and 1889, Saligny planned and built the first silos in the world made of reinforced concrete, which are preserved today in Constanţa, Brăila, and Galați. In the port of Constanța, he designed a special pool to allow oil export and two silos for grain export.
Saligny's most important work was the King Carol I Bridge over the Danube at Cernavodă. Although a public offer had been held by the Romanian government for the erection of a bridge in that location, all projects were found to be subpar and subsequently rejected. Taking Saligny's previous experience into account, the Romanian government hired him and gave him the daunting task to draw up the plans for the new structure. Construction work for the bridge started 26 November 1890, in the presence of King Carol I of Romania. The bridge has five openings, with four being 140 m wide, and the central one spanning 190 m. To allow ships to pass under the bridge, it was raised 30 m above the water. The endurance test was performed on the official opening day, when a convoy of locomotives drove on it at 85 km/h. The bridge at Cernavodă measures 4,037 m in length, with 1,662 m over the Danube, and 920 m over the Borcea Arm. At the time, it was the longest bridge in Europe, and the second longest bridge in the world. The structure was famous for its era, competing with Gustave Eiffel's engineering works in France — the Garabit viaduct and the Eiffel Tower in Paris.
