Description

French mathematician, engineer, and economist (1784-1873) who discovered the geometric concepts now known as the Dupin cyclide and Dupin indicatrix, and developed the first thematic choropleth (color-shaded) map. ALS in French, signed “Ch. Dupin,” one page both sides, 8 x 10, September 27, 1817. Written from Glasgow, a letter to Archibald Constable, a bookseller in Edinburgh, thanking him for his kindness and the introductions to engineers, and for his description of the Caledonian Canal, mentioning also the new lights and works which are much to the credit of "Monsieur Stevenson" [George Stephenson]. In very good to fine condition, with creasing, intersecting folds, and trimming to the integral address leaf. Accompanied by an engraved portrait bearing a facsimile signature.

Traveling to the British Isles, Dupin made a study of the naval defenses, political institutions, and commercial prosperity of the United Kingdom. In one of his books on this subject, Memoires sur la Marine et les Ponts et Chaussees de la France et de l'Angleterre, he describes the mechanics' institutes he found in Glasgow, suggesting that similar ones could be introduced in France.
