Berthe Girardet, the daughter of a rich Swiss merchant and an American daughter of a Naples based merchant, exhibited under her maiden name Imer until her marriage to Swiss painter and engraver Paul Girardet. She often appeared in the Salon of the Societe des Artistes Français. Initially produced under her maiden name, her work consisted mainly of portraits and types as well as genre scenes. After World War I, when her son was killed in action, she concentrated her work on the victims of the conflict and religious motifs. Her 1928 entry Nageuse is shown in the art catalog.
