Jean Huber, portraitiste et peintre de silhouette suisse est connu pour ses portraits du célèbre philosophe des Lumières François-Marie Arouet dit Voltaire. Le peintre sera même surnommé Huber-Voltaire grâce à son amitié avec le philosophe. Il fut le seul peintre à réaliser des portraits du  philosophe de son vivant.  Par l’intermédiaire de Friedrich Melchior Grimm, Catherine II de Russie lui commanda un cycle de peinture présentant Voltaire dans son environnement privé à Ferney. L’artiste nomma cet ensemble composé de neuf toiles « la Voltairiade ».
