In 1941, the Jewish American writer and avant-garde icon Gertrude Stein embarked on one of the strangest intellectual projects of her life: translating for an American audience the speeches of Marshal Philippe Pétain, head of state for the collaborationist Vichy government. From 1941 to 1943, Stein translated thirty-two of Pétain's speeches, in which he outlined the Vichy policy barring Jews and other "foreign elements" from the public sphere while calling for France to reconcile with Nazi occupiers. Unlikely Collaboration pursues troubling questions: Why and under what circumstances would Stein undertake this project? The answers lie in Stein's link to the man at the core of this controversy: Bernard Faÿ, Stein's apparent Vichy protector.
