The struggle of the National Women’s History Museum (NWHM) to make space for women’s history in the United States is in important ways emblematic of the struggle for recognition and status of American women as a whole. Working at the intersections of digital-material memory production and using the NWHM as a focus, this dissertation examines the significance of the varied strategies used by and contexts among which the NWHM and entities like it negotiate for digital, material, and rhetorical space within U.S. public memory production. As a “cybermuseum,” the NWHM functions within national public memory production at the intersections of material and digital culture; yet as an activist institution in search of a permanent, physical “home” for women’s history, the NWHM also counterproductively reifies existing gendered norms that make such an achievement difficult. By examining selected aspects of this complexly situated entity, this dissertation makes visible the gendered nature of public memory production, the digital and material components of that production, and the hybrid nature of emerging public memory entities which operate simultaneously in multiple spheres. Adopting an interdisciplinary approach and guided by Carole Blair’s work on rhetorical materiality, this dissertation explores key aspects of the NWHM’s process of becoming, including an examination of the centrality of the interpellation of publics to the rhetorical materiality of public discourse; an analysis of the material state of public memory production in national history museums in the U.S.; and an exploration of the embodied engagement that undergirds all interaction with and presentation of historical artifacts and narratives, whether digital, physical or both at once. In a synthesis of findings, this dissertation describes a set of key characteristics through which certain hybrid digital-material entities (including the NWHM) enact increasingly complex variations of rhetorical agency. These characteristics suggest a need for a more flexible analytic framework, described in the final chapter. This framework takes shape as an heuristic of functions across which digital-material entities always already enact a situated, active, embodied, and simultaneous agency, one that can account fully for the rhetorical processes through which space is “made” for women in U.S. public memory.
