Louis Bertrand (1731-1812), was a Swiss geologist and mathematician. Bertrand was a pupil of the famous Swiss mathematician and scientist Leonhard Euler and became his close friend. In addition to writing a text on geometry Bertrand also wrote on geology. In "Renouvellemens périodiques des continens terrestres" he discusses the evolution of the Earth’s continents and their renewal, the geological processes that formed mountain ranges, stratigraphic layers, caves and fossils (animal and mineral).
