The tatú, or armadillo in English, is a charming mammal equipped with a dorsal shell that protects it when it curls up on itself. On a transoceanic flight, somewhere between reading about Argentine wildlife and reflecting on the little lamp above his seat—whose beam of light didn’t disturb his wife’s sleep—André Ricard conceived this lamp, which would go on to become a pop-art icon in Europe. A rotatable body to direct the light, with adjustable intensity and a focal lens to widen or concentrate the beam.
