Gaspard de Chabrol

[1] Graduating from the École Polytechnique, Chabrol was designated ingénieur des ponts et chaussées (18 April 1796), but was soon after sent to Egypt as part of the scientific commission which followed Napoleon's campaign.

[6][2] Despite the calls for dismissal of some ultra-loyalists after the Bourbon Restoration, Louis XVIII refused to depose him, claiming that "M. de Chabrol married the city of Paris, and I abolished the divorce".

[9] Under his supervision the first statistical research of the city of Paris was undertaken beginning with 1821, which marked a transition to a more scientific approach to urban planning.

[2] Chabrol was the recipient of the Légion d'honneur in 1811, under Napoleon, and continued to be decorated under the restored monarchy as well, finally being given the highest rank, the Grand Cross of the Legion of Honour, in 1829, by Charles X.

He is credited with originating the phrase "Hundred Days" - les cent jours, in his speech welcoming the returning Louis XVIII.
