In 1862, amateur photographer William H. Mumler of Boston took a self-portrait in his studio, unaware of a ghostly apparition lurking directly behind him. It wasn’t until he viewed the resulting image of a pellucid arm draped casually across his shoulder that he realized the camera must have exposed the lingering spirit of his deceased cousin. With this eerie, novel image, Mumler, a jewelry engraver by trade, became the first of many photographers to claim having photographed a spirit. Photographs like Mumler’s provided timely evidence that spirits of the deceased freely interacted with the world of the living–a discovery he would milk for profit within the framework of the Spiritualist movement.
