Trajetória intelectual de Frederico Waldemar Lange (1911-1988) como elemento de conexão entre a ciência, a região e um projeto nacional

The person of Frederico Waldemar Lange (1911-1988) is at the center of considerable information from the collection of the Paleontology and Stratigraphy Lab of Ponta Grossa State University – UEPG (Brazil). Lange gathered, in an organized, detailed and meticulous way, a rich material which embraces a group of relations in different levels, such as geographical, biological, historical, territorial and regional references. The collection itself and the relationships among the different types of documentation from the History of Geoscience reveal part of the intellectual trajectory of this paleontologist and its role in the development of science in the country.
