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.
