Henry Koster (c. 1793 – 15 May 1820), also known in Portuguese as Henrique da Costa, was an English coffee-grower, explorer and author who spent most of his short adult life in Brazil, writing about his travels, slavery, and other subjects.
[2] He sailed from Liverpool in a ship called Lucy on 2 November 1809, travelling with a family friend, and arrived in Recife, Brazil, on 7 December.
In 1812 he rented an estate at Jaguaribe, where he slept in a hammock in an unfinished church until he could get possession of the big house, bought slaves, and established himself as a fazendeiro, growing and exporting coffee.
While in Brazil, he pursued a particular study of the institution of slavery there, travelling widely, and began to write books about his experiences that were published in London.
[8] Southey mentions the sad loss of his young friend Koster in his Sir Thomas Marc (1831).
