It was long believed that one of the three women in a large portrait of Emma Olivier, Olivia Olivier, and their sister-in-law, Zulmé, was an artist. A recent donation to The Historic New Orleans Collection of three portraits of the Olivier women included a circa-1853 oval portrait signed discreetly with a small letter “Z,” revealing Zulmé Maspero as the painter. The source of Maspero’s training is unknown, but her skill and technical proficiency are comparable with male painters of the same period.
