Carlos Castaneda was most likely born Carlos César Salvador Arana Castaneda on 25 December 1925 in Cajamarca, Peru — though he consistently claimed to have been born in São Paulo, Brazil in 1931. He emigrated to the United States in 1951 and eventually settled in Los Angeles, becoming a US citizen in 1957. He studied sculpture and painting at the Fine Arts School in Lima before emigrating, and later enrolled at UCLA, where he completed a BA in anthropology in 1962 and a PhD in 1973.
The story that made him famous: in 1960, while collecting information on medicinal plants in Arizona for his anthropology studies, he encountered a Yaqui Indian elder named Juan Matus — don Juan — who became his teacher in a shamanic tradition he called the Toltec sorcery lineage. Over the following decade Castaneda underwent an intensive apprenticeship involving peyote, jimsonweed, psilocybin mushrooms and — later — techniques that required no plants. He documented this apprenticeship in a series of books that sold tens of millions of copies worldwide.
Castaneda lived in deliberate obscurity in the final decades of his life — no photographs were permitted, no verifiable biographical information was released. He gathered a group of close female associates known as the witches and developed a movement around his late teachings called Tensegrity — a series of physical movements he claimed to have adapted from don Juan's tradition. He died of liver cancer in Los Angeles on 27 April 1998. His death was not announced publicly for two months.
