French civil engineers

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.
In 1861 he attended and graduated the École Polytechnique in Paris, in 1862 he joined the École nationale supérieure des mines de Paris from which he graduated in 1865 with the title of mining construction engineer.

Paul Séjourné (21 December 1851; Orléans – 19 January 1939; Paris) was a French engineer who specialized in the construction of large bridges from masonry, a domain in which he made some important innovations.

François Hennebique (26 April 1842 – 7 March 1921) was a French engineer and self-educated builder who patented his pioneering reinforced-concrete construction system in 1892, integrating separate elements of construction, such as the column and the beam, into a single monolithic element. The Hennebique system was one of the first appearances of the modern reinforced-concrete method of construction.

Hennebique had first worked as a stonemason, later becoming a builder, with a particular interest in restoration of old churches. Hennebique's Béton Armé system started out by using concrete as a fireproof protection for wrought iron beams, on a house project in Belgium in 1879. He realised however, that the floor system would be more economic if the iron were used only where the slab was in tension, relying on the concrete in the compression areas. His solution was reinforced concrete – a concrete slab with steel bars in its bottom face.
His business developed rapidly, expanding from five employees in Brussels in 1896, to twenty-five two years later when he moved to Paris. In addition, he had a rapidly expanding network of firms acting as agents for his system. These included L.G. Mouchel and F.A. Macdonald & Partners in Britain, and Eduard Zublin in Germany. He was asked in 1896 by Hector Guimard for the terrace of the armory Coutolleau in Angers.

Alain Lipietz (born September 19, 1947 as Alain Guy Lipiec) is a French engineer, economist and politician, a former Member of the European Parliament, and a member of the French Green Party. He has, however, been suspended from the party since 25 March 2014 and is an elected local politician in Val de Bièvre, Paris, France.

Maurice Koechlin (8 March 1856 – 14 January 1946) was a Franco-Swiss structural engineer from the Koechlin family.

Albert Irénée Caquot (1 July 1881 – 28 November 1976) was a French engineer. He received the “Croix de Guerre 1914–1918 (France)” (military honor) and was Grand-croix of the Légion d’Honneur (1951). In 1962, he was awarded the Wilhelm Exner Medal. He was a member of the French Academy of Sciences from 1934 until his death in 1976.

Fulgence Bienvenüe (French pronunciation: [fylʒɑ̃s bjɛ̃v(ə)ny]; 27 January 1852 – 3 August 1936) was a French civil engineer, best known for his role in the construction of the Paris Métro, and has been called "Le Père du Métro" (Father of the Metro).: 162 A native of Uzel in Brittany, and the son of a notary, in 1872 Bienvenüe graduated from the École Polytechnique as a civil engineer: 150  and the same year he began working for the Department of Bridges and Roads at Alençon.: 150  His first assignment was the construction of new railway lines in the Mayenne area, in the course of which his left arm had to be amputated after being crushed in a construction accident.
In 1886, Bienvenüe moved on to Paris to design and supervise the construction of aqueducts for the city, drawing water from the rivers Aube and Loire.: 151  Next, he built a cable railway near the Place de la République and created the park of Buttes-Chaumont.: 151  In 1891, he was appointed as Engineer-in-Chief for Bridges and Roads, the most prestigious engineering job in France.: 151 Paris city officials selected Bienvenüe to become chief engineer for the Paris Métro in 1896. He designed a special way of building new tunnels which allowed the swift repaving of the roads above; this involved (among other things) building the crown of the tunnel first and the floor last, the reverse of the usual method at that time.: 151, 162  Bienvenüe has the credit for the mostly swift and relatively uneventful construction of the Métro through the difficult and heterogenous Parisian soils and rocks.: 150–1, 162  He came up with the idea of freezing wet and unstable soil in order to permit the drilling of tunnels. He was to supervise the Paris Metro construction for more than three decades, finally retiring on 6 December 1932.
Bienvenüe's construction of the Métro was widely praised and has been described admiringly as a work "worthy of the Romans".: 160, 162  He eventually accumulated many honors for his engineering accomplishments, including the Grand Prix Berger of the Academy of Arts and Sciences (1909) and the Grand Cross of the Legion of Honor (1929).: 160 On 30 June 1933, the Avenue du Maine station on the Metro was renamed Bienvenüe in his honor. The naming ceremony took place in his presence; there was a last-minute scramble to repaint the station's new nameboards when it was discovered that the unusual diaeresis in his name had been omitted, making it the French word for "welcome". In 1942 the station was linked to the adjacent Montparnasse station, forming a single station named Montparnasse-Bienvenüe.
Bienvenüe was buried in 1936 at the Père Lachaise Cemetery, Paris.
Lycée Fulgence Bienvenüe  high school in Loudéac, Brittany is named after Bienvenüe.

Jean-Charles Adolphe Alphand (French pronunciation: [ʒɑ̃ ʃaʁl adɔlf alfɑ̃]; 26 October 1817 – 6 December 1891) was a French engineer of the Corps of Bridges and Roads. As a close associate of Baron Haussmann and later as Director of Public Works at Paris City Hall from 1871, he was instrumental in the large-scale renovation of Paris in the second half of the 19th century. In 1889, Alphand was elevated to the rank of Grand Cross of the Legion of Honour. In 1891, shortly before his death, he succeeded Haussmann as a member of the Académie des Beaux-Arts.

Paul Andreu (10 July 1938 – 11 October 2018) was a French architect, known for his designs of multiple airports such as Charles de Gaulle Airport in Paris, and multiple prestigious projects in China, including the National Centre for the Performing Arts in Beijing.

Jacques Antoine Charles Bresse (9 October 1822, in Vienne, Isère – 22 May 1883) was a French civil engineer who specialized in the design and use of hydraulic motors.
Bresse graduated from the École Polytechnique in 1843 and received his formal education in engineering at the École des Ponts et Chaussées. He returned to the École des Ponts et Chaussées in 1848 as an instructor for applied mechanics courses and in 1853 gained his professorship in applied mechanics, after which he taught at the school until his death in 1883.His name is one of the 72 names inscribed on the Eiffel Tower.
