The first collection of essays published on trailblazing nineteenth-century Black feminist, activist, journal, and educator, Mary Ann Shadd Cary Mary Ann Shadd Cary (1823–1893) was a trailblazing Black feminist, activist, journalist, and educator whose achievements can be traced across Canada and the United States. Born in a border state in the antebellum era, Shadd Cary taught in schools in New York, New Jersey, and Pennsylvania before becoming a strong advocate for immigration to Canada in her early adulthood. Once she moved to Ontario in the mid-1850s, she dove headfirst into early Black Canadian debates. She fought to integrate schools in the States and Canada and became, as the editor of the Provincial Freeman , the first Black woman to edit a newspaper in North America. Despite her achievements and impact on Black life in North America, Shadd Cary is a relatively little-known figure outside of the continent. Insensible of Boundaries is the first collection of essays published on this thinker. With this volume, editor Kristin Moriah brings together eleven essays from a broad range of perspectives, including historical, literary, gender, ecological, bibliographical, visual, sound, and performance studies, on nineteenth-century Black feminist inquiry in North America. The volume focuses particularly on three main topics: Shadd Cary’s relationship to immigration, nation, and colonization; the Black creative and nation-building work that Shadd Cary has inspired; and contemporary research methodologies like digital humanities as they can be used to better understand Shadd Cary’s moment, impacts, and life. Through a multi- and interdisciplinary lens, the collection celebrates Shadd Cary’s cultural significance and intellectual contributions, as well as their reverberations in her time and in ours.
