Paul-Adrien Bourdaloue
Paul-Adrien Bourdaloue (* 1798 in Bourges ; † 1868 ibid) was a French engineer and surveyor who founded the French surveying network .
He initially worked in the Corps des ingénieurs des ponts et chaussées ( Corps of bridge and road construction administration ), later an engineer at the railway of the Gard department ( Chemins de fer du Gard ) founded by Paulin Talabot in 1836 .
On behalf of the Société d'Études du Canal de Suez or its member Paulin Talabot, he carried out the surveying of the Isthmus of Suez in 1847 with the support of Linant de Bellefonds, who is active in the Egyptian building administration . In doing so, he refuted the theory that had prevailed until then, which was based on the survey work carried out by Jacques-Marie Le Père during Napoléon's Egyptian expedition , that there was a level difference of more than 9 m between the Mediterranean and the Red Sea .
In 1857 he was commissioned to survey France. Between 1857 and 1863 he created a trigonometric network with 15,000 cast-iron, numbered fixed points and thus the basis of the French national survey.
In the last years of his life he became deputy mayor of Bourges.
He is buried in the Capuchin Cemetery ( cimetière des Capucins ) in Bourges. A surveying point was attached to his grave.
Paul-Adrien Bourdaloue is probably not related to the preacher Louis Bourdaloue (1632–1704), who is also better known to the general public and also from Bourges.
