Auguste Jaccard

Auguste Jaccard (6 July 1833, in Culliairy near Sainte-Croix – 5 January 1895, in Le Locle) was a Swiss geologist and paleontologist.

In around 1845, he moved with his father to Le Locle, where the elder Jaccard opened a guilloché workshop that was later managed by his son.

As a geologist, Auguste Jaccard was self-taught, having Oswald Heer and Pierre Jean Édouard Desor as important influences to his career.

In 1856 he released his first publication, a treatise on fossils found in the basin of Le Locle.

He is credited with creating a geological map that extended to the western part of Switzerland (Neuchâtel, Jura and Vaud).
