My dissertation considers the relationship between the nineteenth century U.S. spiritualist movement, women’s writing, and material media. Spiritualist mediums, many of whom were women, claimed to be able to communicate with the spirits of the dead. Yet, not all spiritualists worked as mediums. I claim in this dissertation that several nineteenth century women writers— Emma Hardinge Britten, Kate Field, Elizabeth Stoddard, Elizabeth Stuart Phelps, Elizabeth Oakes Prince Smith, and Elizabeth Keckley—used spiritualist concepts to articulate their embodied experiences. This project examines the multiple forms of writing, from historical accounts to fiction, through which these authors communicated. Written from 1850-1880, the materials I examine show how women negotiated the contours of the spiritualist movement during the height of its popularity. In order to survey how spiritualist women’s writing operated as a site of embodied religious theorizing, I also examine the material media that these authors took up. Writing and communication media were incredibly influential on the spiritualist movement as markers of progress and potential. I argue that, as a movement inspired by innovations in mediation, it is necessary to consider not just what spiritualist women were writing, but also the media that they used to communicate. Therefore, I show how both conventional and unconventional material media (such as pens, planchettes, the five senses, and sewing needles) appear in these authors’ writings as powerful objects, as literary metaphors, and as bridges between the living and the dead.
