Roger Caillois
After living in the French unoccupied zone, Bénichou could leave in 1942 with his family to Argentina, where he had been offered a teaching position in the university of Mendoza; afterwards, he taught in Buenos Aires, at the Institut Français (co-founded by Roger Caillois). While in the Argentine capital he participated in literary circles and met Jorge Luis Borges, whom he and his daughter, Sylvia Roubaud, would later translate; he also developed a scholarly interest in medieval Spanish literature and published groundbreaking work on the Spanish "romancero".
