Ramón Lista
He was the explorer who lived with the Aonikenk people, learning their language and their customs.
Due to lack of scientific studies about this Patagonian ethnic group before their acculturation and extinction, his writings are an important source for the study of this culture.
Lista wrote: The Tewelche Indians; Buenos Aires (1896); My Explorations and Discoveries in Patagonia. 1877- 1880. Marymar Editions, Buenos Aires (1975).
