Darrell Posey: an engaged researcher

Visionary scientist (idealistic for some), engaged citizen (activist for others), Darrell Posey (1947-2001) impacted for a long time with his passage in indigenous territory. He had the merit of opening a needed debate on the border between cultures, sciences and development involving the Kayapó Indian to his thoughts and actions. He also allowed them to make their voices heard and to defend their rights on a national and international stage.
