American hermits

Theodore John Kaczynski, also known as the Unabomber, was an American mathematician and domestic terrorist. A mathematics prodigy, he abandoned his academic career in 1969 to pursue a reclusive primitive lifestyle and lone wolf terrorism campaign.

Edward Theodore Gein, also known as the Butcher of Plainfield and the Plainfield Ghoul, was an American murderer and body snatcher. His crimes, committed around his hometown of Plainfield, Wisconsin, gathered widespread notoriety in 1957 after authorities discovered that he stole corpses from local graveyards and fashioned keepsakes from their bones and skin. He also confessed to killing two women: tavern owner Mary Hogan in 1954 and hardware store owner Bernice Worden in 1957.

Ishi ( – March 25, 1916) was the last known member of the Native American Yahi people from the present-day state of California in the United States. The rest of the Yahi (as well as many members of their parent tribe, the Yana) were killed in the California genocide in the 19th century. Widely described as the "last wild Indian" in the United States, Ishi lived most of his life isolated from modern North American culture, and was the last known Native manufacturer of stone arrowheads. In 1911, aged 50, he emerged at a barn and corral, from downtown Oroville, California.
