In 1970, Gallimard published a novel that landed like a bomb: The Schizophrenic Sensorial Epileptic and Foreign Languages. Its author? Louis Wolfson, an American and a schizophrenic. The radical newness, the blinding energy of his writing fascinated the era's biggest names: Deleuze, Queneau, Sartre, Beauvoir, Foucault, Auster, and even Nobel laureate J.M.G. Le Clézio. All of them greeted the book as an extraordinary masterpiece. But shortly after this first book was published, Wolfson vanished from the scene, appearing only on rare occasions. The wildest rumors made the rounds about him. Étienne Fabre has set out to tell his story.
