Louis-Léger Vauthier


Louis-Léger Vauthier

Born Bergerac in the Dordogne on 06 April, 1815, Louis-Léger Vauthier was an engineer who designed bridges and roadways and was elected to the French Assemblee nationale in May, 1849 [http://www.assemblee-nationale.fr/histoire/biographies/1789-1889/Tome_5/VAUDREY_VERDOLIN.pdf] , as a member for the departement of Cher.

Although deported for his revolutionary ideas, he became a civil engineer in Spain and then Switzerland before returning to Paris in 1861. He also spent several years in Recife, Brazil.

He is known to have proposed an early idea for a 'Chemin de fer circulaire interieur' in 1865 [Metropoliain by M Passion, Office Technique Graphique, Bibliotheque historique de la ville de Paris, 1988] - which would have formed an early Paris Metro. And again in 1872, 1886 and 1887 he put forward more ideas for an urban transit system in the capital.

In cartography, he is also credited with one of the earliest (if not the first) thematic map to use isolinesto display a non-geographic variable on map--- a contour map of the population of Paris in 1874.
