Arthur Posnansky

Arthur Posnansky (1873–1946), often called "Arturo", was an Austrian engineer, explorer, ship’s navigator, entrepreneur, La Paz city council member, and amateur archaeologist. During his lifetime, Posnansky was known as a prolific writer and researcher and for his active participation in the defense and development of Bolivia. He is well known for his books, including ''Tihuanacu, the Cradle of American Man'', ''Campana de Acre, La Lancha "Iris"'', ''Die Osterinsel und ihre praehistorischen Monumente'', and ''Razas y Monumentos Prehistóricos del Altiplano Andino''. Many, if not most, of his theories have been rejected by modern scholars. Provided by Wikipedia
