Santiago Roth  Santiago Roth (14 June 1850 – 4 August 1924) was a Swiss Argentine paleontologist. Kaspar Jakob (Spanish: Santiago) was born and raised in Herisau, Canton Appenzell Ausserrhoden, Switzerland, as the oldest of 12 children. He attended school in the nearby town of St. Gallen, where his teacher Bernhard Wartmann raised his interest in the science of nature. Wartmann was a well known botanist and director of the Museum of History of Nature in St. Gallen. For economic reasons the Roth family emigrated to Argentina in 1866, where they initially settled in the Colonia Baradero (Buenos Aires Province). There, Roth started a small business with leather goods. In his sparetime he collected plants, butterflies and rocks. He married Elisabeth Schuetz, a teacher educated in Switzerland, who emigrated with her family to Argentina in 1872 as well. After finding the first fossils he became an ardent explorer and collector of extinct mammals. Already in 1878 he was able to sell a collection of fossils to Dr. Laussen, a Dane, who gave these bones to the Museum of Zoology in Copenhagen. Roth was encouraged to continue finding and collecting rare prehistoric mammals as a profession. He contacted Prof. Carl Vogt at the University of Geneva, who was interested to buy a further collection from Roth. The transport arrived in Geneva heavily damaged. Therefore, Roth traveled to Switzerland in 1880 to repair the skeletons in the laboratories of the university. There, he had the additional benefit of being able to attend lectures on geology, zoology and osteology. After his return to Argentina, he continued his search in the basin of the Paraná River and in the Entre Ríos Province belonging to the Pampas. He published his findings in his mother tongue, German. Roth was continuously looking for buyers to generate income for his large family. Such an opportunity arose in 1887 when he traveled to Switzerland with his family. The Swiss geologist Prof. Albert Heim, ETH Zurich had recommended that the Swiss authorities should buy his collection nr. Today, this collection is held by the Museum of Zoology at the University of Zurich and includes a huge, extinct ground sloth (Megatherium) as well as a large armored mammal (Glyptodon). A special exhibition including the Roth collection was organized in 2000. During his stay in Switzerland he joined Albert Heim on his hydrogeological excursions to study subterranean water flows.
