Jean-André Deluc

Jean-André Deluc (also: Jean-André de Luc ; born February 8, 1727 in Geneva ; † November 7, 1817 in Clewer near Windsor ) was a Swiss geologist and meteorologist . He was a pioneer of stratigraphy in geology.

Life

Deluc was the son of the wealthy watchmaker and writer Jacques-François Deluc. He should become a businessman, studied science and mathematics and began to be interested in geology and palaeontology and collected minerals, rocks and fossils in the Alps and the Swiss Jura. He became famous for improvements to the thermometer (using mercury instead of alcohol), invented a hygrometer made of ivory and built barometers . He improved the barometric height formula of Edmond Halley .

He was a member of the Geneva People's Party and in 1770 became a member of the Grand Council (Council of Two Hundred). In 1768 he was ambassador to Bern and Paris. In 1774 he went to London , where he was a reader of the Queen of England Sophie Charlotte of Mecklenburg-Strelitz . In 1798 he was appointed honorary professor of philosophy and geology in Göttingen , but never lived there, but alternated between Berlin , Hanover , Braunschweig and London.

He was involved in scientific disputes with Horace Bénédict de Saussure (on barometry) and James Hutton (on erosion ). The latter controversy was u. a. determined by the opposing positions of the two scholars on geological history. While Hutton was one of the trailblazers of actualism , Deluc took an explicitly catastrophic point of view in geological terms , assuming repeated geological revolutions ( cataclysmic upheavals).

He was a Fellow of the Royal Society , a member of the Académie des Sciences and, since 1808, a foreign member of the Bavarian Academy of Sciences . In 1815 he was elected a foreign member of the Göttingen Academy of Sciences .

The lunar crater Deluc is named after him.
