Fr. Bernhard Havestadt (1714-1778), a German Jesuit, was the author of one of the two 18th century grammars of Mapudungun. A native of Köln, he left the Westphalia monastery of Horst-Maria for the ‘Indies’ in 1746, taking up his post in the region of La Frontera in March of 1748. Here he remained for twenty-two years, leaving a lively record of his evangelisation work and travels.
His grammar,though apparently available in a Spanish-language manuscript in the mid-1750’s, was published — in Latin — only in 1777 as Chilidúģu: Sive Tractatus Linguæ Chilensis.
