Since the 1960s, Deanna Petherbridge's practice has moved between making drawings and writing critically about art and architecture. She has designed murals and stage-sets, curated exhibitions, taught in the studio and lectured internationally - a career trajectory that has anticipated the multiple practices of younger conceptual artists. Drawing is her primary concern, both as an artist and as a historian of practice. Her book, The Primacy of Drawing: Histories and Theories of Practice is the preeminent study in the field; and her drawings are to be found in many major collections. This monograph, first published to coincide with a retrospective at the Whitworth Art Gallery, celebrates the vitality and originality of an extraordinary body of work.
