In 1911, a mysterious Native American man called Ishi emerged from the North Californian forest after more than three decades in hiding. He is thought to be the last survivor from the Yahi tribe. Ishi became a tourist attraction in San Francisco and many recordings were made of his stories and music.
In 2012, Louise Hidalgo retraced his story. She spoke to the author Ursula Le Guin and filmmaker Jed Riffe.
