Sydney Ferreira Possuelo, is a Brazilian explorer, social activist and ethnographer who is considered the leading authority on Brazil's remaining isolated Indigenous Peoples.

Life and work

Sydney Possuelo started his career assisting the famous Villas Boas brothers with their work among indigenous peoples of the Xingu River area. Later he became the Director of the Department of Indigenous in Isolation at the FUNAI, doubling the surface size of officially designated Indigenous land in Brazil in only two years.
Working in the most isolated areas in the Amazon region, Possuelo has led many expeditions, getting in contact with isolated tribes in Brazil, with the aim to protect them from other threats. He was responsible, among others, for the restoration of peaceful contact with the Korubo Indians, who had previously killed some FUNAI officials.
For his many efforts Sydney has received many prizes, including honors from the National Geographic Society, Bartolomeu de las Casas in 1998, a gold medal from the Royal Geographical Society, the title of "Hero of the Planet" by Time Kids Magazine, as well as "Hero of the year" 2001 by United Nations.
Until January 24, 2006 he was head of the FUNAI Department of Unknown Tribes, a governmental bureau responsible for protecting the land and lifestyle of isolated tribes from encroaching settlers. Days earlier, he had criticized FUNAI director Mercio Pereira Gomes for suggesting that Brazilian Indians held too much land, comparing Gomes to "ranchers, land-grabbers, miners, and loggers." Soon afterwards, Possuelo was dismissed from his position.
Possuelo is still continuing his efforts at defending isolated tribes through the non-governmential Instituto Indigenista Interamericano.
Possuelo is the main protagonist in the book The Unconquered: In Search of the Amazon's Last Uncontacted Tribes by National Geographic writer Scott Wallace. It details a 76-day expedition in 2002 led by Possuelo to find the status of the "Arrow People", an uncontacted tribe in the Vale do Javari Indigenous Land.
