Английская Википедия:Charles Dupin
Шаблон:Short description Шаблон:Expand French Шаблон:Infobox scientist Baron Pierre Charles François Dupin (6 October 1784, Varzy, Nièvre – 18 January 1873, Paris, France) was a French Catholic mathematician, engineer, economist[1] and politician, particularly known for work in the field of mathematics, where the Dupin cyclide and Dupin indicatrix are named after him; and for his work in the field of statistical and thematic mapping.[2] In 1826 he created the earliest known choropleth map.[3]
Life and work
He was born in Varzy in France, the son of Charles Andre Dupin, a lawyer, and Catherine Agnes Dupin.[4] His elder brother is André Marie Jean Jacques Dupin.
Dupin studied geometry with Monge at the École Polytechnique and then became a naval engineer (ENSTA). His mathematical work was in descriptive and differential geometry. He was the discoverer of conjugate tangents to a point on a surface and of the Dupin indicatrix.[5] Dupin participated in the Greek science revival by teaching mathematics and mechanics lessons in Corfu in 1808. One of his students was Giovanni Carandino, who would go on to be the founder of the Greek Mathematics School in the 1820s.
From 1807 Dupin was responsible for the restoration of the damaged port and arsenal at Corfu. He founded the Toulon Maritime Museum in 1813.
In 1818, Dupin was elected to the body of the French Academy of Sciences, one of the Institut de France's five Academies.[6]
He was appointed professor at the Conservatoire des Arts et Métiers in 1819; he kept this post until 1854. In 1822, Dupin was elected a foreign member of the Royal Swedish Academy of Sciences. He was made a baron in 1824. In 1826 he published a thematic map showing the distribution of illiteracy in France, using shadings (from black to white), the first known instance of what is called a choropleth map today.[3] Dupin had been inspired by the work of the German statisticians Georg Hassel and August Friedrich Wilhelm Crome.[2] Dupin was named rapporteur for the central jury of the Exposition des produits de l'industrie française en 1834. For each branch of industry he noted the quantities and value of French exports and imports, with comparative figures for 1823, 1827 and 1834.[7]
Dupin also had a political career and was appointed to the Senate in 1852.[6]
