Alexandre Félix Gustave Achille Leymérie
Alexandre Félix Gustave Achille Leymérie (born January 23, 1801 in Paris , † October 5, 1878 in Toulouse ) was a French professor at the Faculty of Mineralogy and Geology at the University of Toulouse and a corresponding member of the Académie des Sciences .
Leymerie had studied at the École Polytechnique and taught geometry and applied mechanics at the Collège in Troyes from 1827. He also studied geology and mineralogy. In 1833 he became a mathematics professor at the École Industrielle de la Martinière in Lyon. In 1837 he was in Paris and heard lectures from the most famous French geologist Élie de Beaumont , who wanted to establish geology as an independent discipline in France. In 1840 he received his doctorate and became a professor in Toulouse.
Leymérie specialized in his work on the geology of the Pyrenees and Aquitaine , more precisely the Aquitaine basin . Among other things, he is considered to be the first to describe the minerals iodargyrite and ranciéit .
He saw the Pyrenees as a model for studying mountain formation (before any other mountain range in the world) and had a very practical, almost "physical" relationship to them. His powers of observation in his field studies were praised by Leopold von Buch , among others .
In 1853 he was involved in a scientific dispute with the director of the observatory in Toulouse Frédéric Petit (1810-1865), when he claimed the Pyrenees were hollow, which he concluded from pendulum observations that had shown no gravity influence of the mountain range.
