Theodor Koch-Grunberg

Theodor Koch-Grünberg (April 9, 1872, in Grünberg, Hesse, German Empire – October 8, 1924, in Caracaraí, Brazil) was a German ethnologist and explorer who travelled and studied the Indigenous peoples in South America, in particular the Pemon of Venezuela and other indigenous peoples in the Amazon region extending South-Western Brazil and a large part of the Vaupés region in Colombia. The 2015 film ''El abrazo de la serpiente'' (''Embrace of the Serpent'') fictionalizes his illness and final days based on his journals. Provided by Wikipedia
