He attended the prestigious Lycée Louis-le-Grand (school) a few hundred meters to the south of the city centre, and then relocated to London where he began a business career, working for a banker.
In 1826 he took over his father's book dealership, installing himself and his business in an imposing town house back in Paris.
The marriage produced a son, Léopold Renouard (1833-1910) who in due course would become a leading Paris banker.
[3] His second marriage was to Amélie Talabot (1810-1869)) and took place on 27 October 1837, producing in due course five recorded children including Georges Renouard (1843-1897) who much later would marry a daughter of Baron Haussmann, France's most famous city planner.
[3] Renuard was a founder member of the Cercle de la librairie (Book dealers' association) founded in 1847, and himself delivered an important paper to the association in 1851 under the title "Progrès de la contrefaçon, dénonciation et protestation", protesting against the unfair trading practices of foreign competitors.
