Man of the Hole
It is not known what language the Man of the Hole spoke, what his people called themselves, or what his name was. He was the last surviving member of his people after Brazilian settlers killed the other people of his group in  a  genocide   in the 1970s–1990s. The Man of the hole lived alone from the mid-1990s until his death in 2022. From 1996, the Brazilian Fundação Nacional do Índio (FUNAI) monitored and occasionally interacted with him from a distance, but he otherwise chose to remain isolated. Living primarily by hunting and gathering and moving frequently, he left behind a deep hole of unknown purpose in each of his homes. This was the reason for his nickname. The Man of the Hole survived another attack by an armed rancher in 2009. In 2018, his case attracted international attention when FUNAI released a video of him to raise awareness about the threats uncontacted peoples  faced in Brazil. He was found dead in one of his homes in August 2022.
