Louis Rollier
Louis Rollier (born May 19, 1859 in Nods BE ; † June 3, 1931 in Zurich ) was a Swiss geologist and paleontologist .
Rollier came from a family of farmers and craftsmen. He grew up in La Neuveville and attended the Collège in St-Imier . From 1876 he studied geology in Porrentruy and then at the ETH Zurich with Albert Heim , Oswald Heer and Karl Mayer-Eymar . In 1880 he received his diploma with a thesis on the geology around Besançon and graduated as a specialist in natural sciences. He taught at the secondary school in St-Imier and also dealt with geological and palaeontological research in the Swiss Jura . In 1899 he received an honorary doctorate from the University of Bern and was commissioned by the Swiss Geological Commission to revise the geological map in the Bernese Jura.
In 1902 he became an assistant at the Geological Collection in Zurich and after the death of Karl Mayer-Eymar in 1908 he became his successor as curator of the collection. From 1903 he was a private lecturer in stratigraphy and paleontology at the University of Zurich and the ETH. In 1911 he became an adjunct professor at the ETH.
He put on a geological-paleontological collection several times. He sold the first collection to the Schwab Museum in Biel ; the later ones went to the ETH collection.
Rollier played an important role in building a stratigraphy of the Swiss Jura. As a paleontologist, he mainly dealt with Jura and Tertiary invertebrates .
At times, like many other Swiss geologists, he worked as an engineering geologist, for example at the Lötschberg tunnel . In 1906 he expressed his skepticism about an older geological report from 1900 and feared that alluvial sediments in the Gastern Valley could reach deeper than assumed in the old report and that tunneling there would be dangerous. On July 24, 1908, his fears came true when water and sediment ingress in the tunnel, killing 25 Italian tunnel workers. Rollier then turned away from engineering geology.
He remained a bachelor throughout his life.
