F. Hennebique was born in France, in the family of a farmer. Already in his childhood he became fond of natural sciences and spent his free time on reading books on natural sciences. At the age of 18 he became an apprentice of a builder and at the same time he continued his studies of theoretical technology. At the age of 25 years Hennebique specialized in restoring churches. He travelled all over the country visiting cathedrals and examining their architecture and construction.
As years passed by, he grew interested in railway works, including bridges and viaducts. In 1844 he designed a house for a client and, to prevent damage by fire, combined good-quality steel with concrete in compression. In this way he realized a new idea to put steel rods in the bottom of the slab in order to prevent any damage by fire. That building with its fire resistance guarantee was completed in 1880 and stood until destroyed during the First World War.
From that time on, F. Hennebique concentrated on the development and production of reinforced concrete constructions. One of his reinforced concrete buildings of that time, a single-storey structure in Paris, had a concrete and glass roof.
