Edmond Coignet
Edmond Coignet (born July 4, 1856 in Ville-d'Avray , † March 29, 1915 in Paris ) was a French civil engineer who erected the first reinforced concrete structures in Paris.
Edmond Coignet was the son of the reinforced concrete pioneer and entrepreneur François Coignet (where the reinforced concrete was called Béton agglomérés ). He studied at the École centrale des arts et manufactures , which he graduated in 1879. In the 1890s he developed with Napoléon de Tédesco (1848-1922) design rules for reinforced concrete, which they presented in 1894 to the Académie des sciences et la Société des ingénieurs civils. Around the same time, Gustav Adolf Wayss and Mathias Koenen ( Zentralblatt der Bauverwaltung 1886, Monier brochure with Wayß 1887) in Germany and Paul Neumann (1890) in Austria presented calculation approaches . They also made experiments on reinforced concrete.
Coignet converted his family business to building construction and reinforced concrete prefabricated components (the company Constructions Edmond Coignet ). Coignet its calculation method turned first in the construction of the aqueduct of Achères and was then reinforced concrete parts in the dome of the station of Antwerp , the Adolphe Bridge in Luxembourg and the casino in Biarritz involved. In Paris he erected some of the first reinforced concrete buildings with the architect Jacques Hermant (1855-1930), the Magasin aux Classes Laborieuses in the Rue Saint-Martin in 1899 and the Salle Gaveau in the Rue Saint-Honoré. Until his death he was President of the Chamber of Commerce in Lyon .
